What's New in Lab Research Hub 6.5.2 This update delivers a complete milestone monitoring and reporting system, giving supervisors full visibility into every student's progress — and giving students a clear, structured path to completion. Live Milestone Progress Tracking Students can now update their progress (0–100%) on every supervisor-assigned milestone. A live progress bar appears on the supervisor's Lab Milestones list, updating in real time. No more guessing where a student stands. Progress History Timeline Every progress update is logged with a date, time, and optional student note — creating a permanent, auditable timeline of effort. Supervisors can see exactly when a student moved from 30% to 75%. Supervisor Comments on Progress Supervisors can leave feedback directly on any progress entry. Students receive an immediate push notification and see the comment inline in their history timeline. Auto-Achieve at 100% When a student sets progress to 100%, the app prompts them to officially mark the milestone as achieved — closing the loop in a single tap. Progress Chart on Student Profile Tap any student in Progress Overview and select a milestone to view a date vs % line chart. Achieved milestones are shown with a green checkmark badge for a complete historical view. Bulk PDF Export A single "Export All" button on the student profile generates a professional PDF covering every milestone, its progress bar, full history timeline, and all supervisor comments — ready to share or archive. Meeting Minutes — Live Archive & Auto-Backup The Previous tab now reads directly from the live database — always current, no backup file needed. Every time minutes are endorsed, a full lab backup is automatically pushed to Google Drive. Browse Backups entries now show the exact backup date, time, and file size.

What's New in Lab Research Hub 6.1.0 This release is the largest update to Lab Research Hub since launch - bringing a fully redesigned meeting minutes system, a live archive, automatic Google Drive backup, and deep security hardening across every feature. Meeting Minutes - Complete Overhaul All lab members can now create, draft, and submit meeting minutes - not just supervisors. A new two-button flow (Save Draft / Submit to Supervisor) mirrors the logbook workflow, keeping work private until it is ready. Endorsed minutes now require a second confirmation before deletion, protecting official records. Live Minutes Archive The Previous tab now shows all lab minutes in real time, directly from the database. No backup file needed. Records are always current, always accurate, and always isolated to your lab. Auto-Backup to Google Drive on Endorse Every time minutes are endorsed, a full lab backup is automatically pushed to your connected Google Drive — silently, in the background. Your Drive stays in sync without any manual action. Browse Backups - Backup Date & Size The Browse Backups tab now shows the exact date, time, and file size of every Drive backup, so you can immediately identify which snapshot to inspect. Logbook PDF - Fully On-Device The logbook PDF is now generated entirely on your device using native print. No server URL, no authentication required. Share directly to WhatsApp, Email, Files, or AirDrop from the native iOS share sheet. Student Pledges for Supervisors Supervisors can now browse all shared monthly pledges from their students - view task lists with progress bars, and add or edit inline comments directly from the app. Unified Milestones Screen Milestones and Personal Reviews are now a single screen with role-based tabs. Supervisors see Lab Milestones and Personal Reviews awaiting endorsement. Students see Supervisor-assigned and Personal milestones side by side. Stability & Bug Fixes Fixed PDF unauthorised error in emailed links (signed JWT token). Fixed Drive photo attachments not rendering in logbook. Fixed redirect URI mismatch in Google OAuth. Fixed admin accounts being incorrectly frozen. Fixed new member notifications being sent to all labs instead of the registering lab only. Fixed Add Event keyboard overlap on attendees and description fields.

This release focuses entirely on security hardening and quality assurance. No new features have been added; all changes are under the hood. Security Every data access path in the app has been audited and hardened. Users can no longer access records, documents, or data belonging to other research labs, even by guessing internal record IDs. This applies to logbook entries, tasks, meeting minutes, inventory, instrument bookings, milestones, publications, announcements, and PDF exports. Background notifications (inventory expiry reminders, new member alerts) are now strictly scoped to each lab.

Lab Research Hub 5.7.5 A Master Isolation Guard centrally enforces that every data read, write, and export is strictly scoped to the requesting lab - with automatic audit logging of any cross-lab access attempts. The Google Drive connection status indicator on the home dashboard has been restored.

Google Drive Integration - Fully Overhauled Lab admins no longer need to enter any credentials. Simply tap Connect Google Drive in Lab Settings and sign in with your Gmail - that's it. All uploaded files (photos, logbook attachments, vault documents) go directly to each lab's own Google Drive. Drive Status Indicator A small green/red dot appears beside the notification bell on the home dashboard (admin only). Green = Drive connected. Red = not connected. At-a-glance visibility without entering settings. Bug Fixes - Fixed Error 400: redirect_uri_mismatch that blocked Google sign-in - Fixed logbook photo attachments showing as blank black boxes Privacy & Isolation - Every lab's data, files, and Drive tokens are completely isolated. No lab can access another lab's data. No files are stored on developer/Manus server space.

Version 5.3.1 - Your Lab. Your Drive. Your Data. This release brings Google Drive cloud backup fully to life - with complete lab isolation, a built-in setup guide, and a suite of smart admin tools. Google Drive - Fully Lab-Isolated Each lab connects its own Google account. Your backups go to your Drive only - no other lab can ever see or access your data. Isolation is enforced at the database level. Built-In Setup Guide A step-by-step Google Drive setup walkthrough lives directly in Lab Settings - tap to copy your redirect URI, open Google Cloud Console in one tap, and get connected in minutes. Includes a clear "App not verified" guide so nothing blocks you. Test Your Connection Verify your Drive token is live and see exactly how many backup files exist - right from Lab Settings, no guessing. Backup Status at a Glance See "Last backed up X days ago" with a green tick when recent and an orange warning when overdue. Always know your lab's backup health. Invite Code Housekeeping One tap removes all expired and revoked invite codes. Active codes are always kept safe. Leave Lab Members can now cleanly leave a lab from the More screen, with a confirmation step before any change is made. Smart Notification Deep-Links Tapping any notification takes you directly to the exact record - log entry, task, event, meeting minutes, milestone, or leave application. Lab Research Hub - built for real research workflows.

Version 4.15.1 New users and anyone evaluating Lab Research Hub can now experience the full app immediately, without entering a single piece of real data. The moment a new lab administrator opens the app for the first time, the system automatically populates every module with realistic, clearly labelled [DEMO] sample data drawn from a real research context. • Rich text formatting (bold, italic, underline, bullets, numbered lists) now renders visually on log entry, meeting minutes, task, and announcement detail screens. • Document Vault: documents now open in a secure in-app viewer with screen-capture prevention. • Document Vault: admins and lab managers can view a per-document access log showing who viewed it and when. • Document Vault: optional expiry date on uploaded documents — expired documents are automatically hidden from members and flagged for admins. • Meeting minutes now capture all fields (discussions, decisions, next meeting date) and auto-email an HTML copy to all lab members upon endorsement. • Event details now correctly display attendees and description/notes. • Event creation supports selecting attendees directly from the members list. • Bug fixes and performance improvements.

What's New in Lab Research Hub 4.3.2 Monthly Pledge — Milestone Linkage Link your monthly goals directly to research milestones. Completing a linked goal automatically marks the milestone as achieved. Student Performance Report Supervisors can now view a full yearly performance summary per student, including task outcomes, monthly achievement breakdown, and a PDF export for annual appraisals. Monthly Pledge Supervisor Overview Supervisors can browse all students' shared monthly pledges side-by-side and leave written feedback. Non-Compliance Notifications Students are immediately notified when a supervisor closes a task as non-compliance, with the reason included. Bug Fixes & Improvements - Leave applications now correctly appear in supervisor notification centre - Multi-event creation is significantly faster - Logbook photo thumbnails can be tapped to view full-screen

Task Management • Reassign with Date & Time — When reassigning a task to another member, you can now update the due date and time directly in the reassign modal. The new date is pre-filled from the existing due date for convenience. • Return with Comment — Keyboard Fix — The comment box in the Return with Comment modal no longer gets covered by the keyboard on iOS. The modal now scrolls up automatically when the keyboard appears. Inventory & Stock • Chemical Naming Standard (IUPAC) — Stock item names now follow Modified Sentence Case per IUPAC convention (e.g., Iron(II) sulfate, Hydrochloric acid 37%). An info button next to the name field opens a quick IUPAC naming guide. • Maker / Manufacturer Field — A new Maker field has been added to all stock items, available in both the Add Item form and the inline edit view. • Edit by Advisor & Lab Manager — Advisors and lab managers can now edit stock item fields (name, location, supplier, maker, notes) for any registered item, not just items they originally added. • Export to Instrument List — Equipment items can now be exported directly to the Instruments list with a single tap. Available to lab managers and admins only. • Instrument Edit by Lab Manager — Lab managers can now edit instrument details, in addition to admins. Notifications • Overdue Task Reminders — Students receive a direct, serious push notification when a task becomes overdue: "Task Overdue!! Your task '[title]' was due on [date]. Please update your progress or reach out to your supervisor — timely communication is key in research." • Snooze 3 Days — Advisors can snooze an overdue reminder for 3 days from the task detail screen. The student will be re-notified after the snooze expires. The snooze-until date is shown in the confirmation alert. • Milestone Achieved → Advisor Notified — When a student marks a supervisor-assigned milestone as achieved, the advisor now receives a push and in-app notification for review. • Leave Result → In-App Notification — When a leave application is approved or rejected, the student now receives both a push notification and an in-app notification. • Registration Notifications Cleaned Up — Admin registration notifications are no longer sent for advisor or admin self-registrations. Only student/member registrations that require approval trigger the notification. Student Progress & Statistics • Persistent Student Statistics — The per-student statistics panel (tasks assigned, completed, logs recorded, milestones, leave days) now loads directly from the database and persists even if a student's membership is archived or their lab code is cleared. Personal Milestones • Share with Supervisor — Students can share personal milestones with their supervisor for endorsement. A "Share with Supervisor" button appears on each personal milestone card. • Supervisor Endorse / Return — Advisors can endorse or return shared personal milestones from the student's progress screen, with an optional comment on endorsement and a required comment on return. • Endorsed Milestones Stay Visible — After endorsement, personal milestones remain in the student's Personal tab with a green "Supervisor Endorsed" badge. The progress bar remains fully editable so students can continue updating their progress. • Progress Bar in Advisor Panel — The advisor's student progress screen now shows a visual progress bar and percentage for each shared personal milestone, alongside the title and advisor status badge.

Version 2.0.7 — What's New Improved Logbook Review Cycle The formal review process is now clearer and more robust. After an advisor returns a log entry with comments, the student can submit a written response. The advisor is immediately notified and can review again — endorsing or returning as many times as needed until fully satisfied. Each review round is recorded in a dedicated Formal Review Cycle section, clearly separated from the general Discussion Thread. Once endorsed, the log entry is permanently sealed. First-Time Lab Setup Wizard New advisors are guided through a 3-step setup wizard on first login: name your lab, generate an invite code, and start inviting members. The wizard reappears until the lab name is saved, ensuring no advisor is left with an unconfigured lab. Bug Fixes & Stability Resolved a background task error related to task reminder processing. General database and server stability improvements.

Version 2.0.6 What's New Independent Lab Support Each advisor who registers now gets their own isolated lab. Lab members, logbooks, tasks, announcements, inventory, and all other data are fully separated between labs. Advisors from different institutions can now use the app independently without any data overlap. Improved Logbook Review Cycle The formal review process between advisor and student is now clearer and more robust. After an advisor returns a log entry with comments, the student can submit a written response. The advisor is then immediately notified and can review again — endorsing or returning as many times as needed until fully satisfied. Each review round is recorded in a dedicated Formal Review Cycle section, clearly separated from the general Discussion Thread. Once endorsed, the log is permanently sealed with a visible endorsement record. Bug Fixes & Performance Resolved a background task error that occurred when processing task reminders. General stability improvements and database optimisations.

Version — What's New This update brings important reliability and compatibility improvements for all users. Bug Fixes & Improvements - Fixed an issue where users on iPad and iPhone could not sign in due to a network connectivity error - Sign-in now works correctly regardless of uppercase or lowercase letters in your email address (e.g. GS74322@student.upm.edu.my and gs74322@student.upm.edu.my are now treated the same) - Fixed an issue in Lab Settings where OAuth redirect URIs displayed an incorrect server address - Improved stability of the Google Drive integration for admin users on real devices - A timezone conversion bug caused event start and end times to shift by 8 hours when created on devices set to GMT+8 (Malaysia Standard Time). - Events created in version 1.0 with incorrect times should be deleted and recreated. All new events are stored and displayed correctly in local time.

This update brings major improvements to inventory management, instrument tracking, GLP compliance reporting, and app stability. INVENTORY — PER-UNIT TRACKING Each unit in your chemical stock now has its own expandable card showing current balance, amount used, batch number, expiry date, and full usage history. Multiple lab members can log usage against the same unit simultaneously. Balance After is auto-calculated when logging usage. A low-balance warning badge appears on any unit below your configured threshold. You can set a custom alert threshold per item (5%–25%). Multi-batch registration lets you add several batches in one session, each with its own batch number and expiry date. Expiry dates now use a native date picker. INVENTORY — AUTOMATED EXPIRY ALERTS The app now sends push notifications automatically when any sealed unit is 30 days and 7 days from expiry, listing the item name, unit number, batch, expiry date, and storage location. All lab members receive these alerts. INVENTORY — STATUS & AUDIT Inventory status (Available, In Use, Low Stock, Out of Stock) is now fully automatic — derived from actual unit counts in real time. Each item shows who registered the stock and when. The Last Used By field updates automatically every time usage is logged. INSTRUMENTS — BOOKING IMPROVEMENTS Instrument bookings are now auto-confirmed immediately with no approval step. If your requested time slot conflicts with an existing booking, you will see an alert with the conflicting details and a prompt to choose a different time. Each booking card now has Complete and Cancel buttons. Completing a booking automatically marks the instrument as Available and records who used it last. Booking history older than 30 days is cleared automatically. Booking history can be exported as a CSV file and shared via email or saved to Files. INSTRUMENTS — LAST USED DISPLAY The instrument detail card now shows "Last used by: [Name] on [Date]" — giving the lab manager a quick audit trail without opening the full booking history. GLP COMPLIANCE — EXPORT REPORT The Export GLP Report button is now active on every inventory item detail screen. Tapping it generates a complete plain-text audit trail with two sections: Section 1 — Inventory Usage Log: every withdrawal for that item (user, unit, amount, balance, purpose, date and time). Section 2 — Instrument Booking History: the full booking record across all lab instruments (instrument, user, start and end time, status, purpose). The report can be emailed, saved to Files, or printed via the system share sheet. BUG FIXES Fixed a crash that occurred immediately when tapping Edit on a unit card (caused by an internal date format mismatch). Fixed the Log Usage form not submitting in some scroll positions. Removed the manual status picker — status is now a read-only auto-derived value. Zero errors confirmed across the entire codebase. Thank you for using Lab Research Hub.

This update brings major improvements to instrument management, sign-in, member roles, and privacy. Instrument Photos and QR Codes Each instrument in your lab now has its own photo — upload a picture so members can identify equipment at a glance. Admins can replace or remove the photo at any time. Every instrument also gets a unique QR code: print it, stick it on the physical instrument, and any lab member can scan it with their phone camera to open the booking screen instantly — no searching required. Compact Instrument Filters The All / Available / In Use / Booked / Maintenance filter buttons are now compact, scrollable chips that fit neatly in a single row. Role Change Requests Lab members can now formally request a role upgrade (for example, from Master to PhD) directly from their Settings screen. The advisor reviews all pending requests from the Members screen and approves or rejects with one tap. Both parties are notified instantly. The member's account stays fully active throughout the review — no disruption to their work. Improved Sign-In for Everyone The SSO (Single Sign-On) button now validates your invite code before opening the sign-in portal — no more silent failures. After sign-in, your selected role is applied correctly. Advisors registering via SSO for the first time are greeted with a welcome guide explaining how to set up the lab, generate invite codes, and invite members. Privacy Policy A full privacy policy is now available at https://hydrochemistry.my/privacy, covering all data practices in plain language. Bug Fixes Fixed SSO redirect errors on some devices. Fixed advisor registration incorrectly requiring an invite code.

Version 1.0.2 — Stability & Security Update • Fixed a crash that could occur on the registration screen on some iPhone models • Improved app security: unauthenticated access to lab screens is now fully blocked • Fixed an issue where certain icons did not display correctly on iOS • Improved publications screen to correctly reference Scopus (Elsevier API) • Removed debug logging for improved performance and privacy • General stability improvements and bug fixes
