A stability and data safety update. -Fixed a rare problem where the app could fail to open. It now recovers on its own instead of leaving you stuck. -Fixed an issue that could delete photos attached to your records while the app was recovering. Your photos are now protected. -Import Preview no longer changes your real tasks and timer presets when you tap Cancel. -Fixed crashes in the Cell Seeding and Hydrogel calculators, and when opening certain cultures. -Reagent concentrations typed with a comma, like 0,5, now save correctly. -Deleting or renaming a procedure category no longer hides the protocols inside it. Anything already affected reappears under "Other". -Fixes to backup restore, Apple Watch task reminders, and the interactive guides.

Learn the app with interactive guides Not sure how something works? Tap "How the app works" on the Reference tab and pick a walkthrough. The app then guides you step by step on the real screens: it highlights the actual button to tap and follows along as you move from screen to screen. 16 walkthroughs cover the everyday workflows, including adding cell lines, reagents and freezer vials; creating and linking experiments; feeding, splitting and freezing cultures; building and running timed protocols; plate layouts; the lab notebook; lab timers; the Today board; the calculators; search; and backup and iCloud sync. Also new: A short first-run tour shows where the guides live, so help is always one tap away. The old one-time pop-up tips are replaced by these interactive guides.

The biggest update yet. iCloud Sync is here! Cultures, experiments, reagents, freezer items, notebook entries, plate layouts, tasks, recipes, protocols, equipment, photos: all sync automatically across your iPhone, iPad, and Mac. Pick up where you left off, wherever you are. WHAT YOU'LL NOTICE FIRST - Sync just works. No accounts, no setup, no extra taps. Sign in to iCloud and you're good. - Photos sync too. Attach a gel image on iPad, see it on iPhone moments later. - The full freezer hierarchy syncs (Tank, Rack, Box), every vial in its right slot. PRIVATE BY DESIGN Your data lives in your private iCloud database. Only your signed-in Apple devices can read it. The developer never sees it. No tracking, no analytics, no accounts. PEACE OF MIND If iCloud sync ever stalls, a clear banner explains the situation and the Delete All Data button gets gated, so a single tap can't accidentally wipe data that hasn't reached the cloud yet. PLUS A LOT MORE - Hundreds of polish fixes across freezer, cultures, notebook, notifications, Spotlight, and the audit log. - Major reagent detail navigation freeze, fixed. - MOI calculator now covers lentivirus (TU/mL), AAV (VG/mL), and IU/mL alongside PFU/mL and TCID50/mL. - Dates display DD/MM/YYYY everywhere, regardless of system locale. App preferences (Lab Identity, alert toggles, theme) intentionally stay per device. Set them once on each. Thanks for the bug reports and feedback. Many of them landed in this release.

New features are built from your feedback. Have more ideas? Tap 'Send Feedback' in App or leave a review in AppStore. v1.8.1 connects the dots: -Cultures, cell lines, experiments, reagents, equipment, virus stocks, frozen vials, and plate layouts now show up in iOS Spotlight. Swipe down on your home screen, type a name, tap straight to the record. -Tasks finally know what they belong to. When you create one, link it to a culture, experiment, reagent, equipment, or any other lab item. Open that record later and the task is right there. Same for notebook procedures (pin one to a culture and it appears in that culture's history). -Six calculators (Hemocytometer, Viability, Freezing, Seeding, MOI, Transfection) can save their result straight to a culture or experiment. Frozen vials remember the culture they came from. -Three new Siri shortcuts: "add culture observation", "log feed", "check equipment". Hands-free at the bench. -Apple Watch gains a Today's Tasks tab with tap-to-complete sync. The Lab Notebook lets you swipe right on auto-recorded entries to keep them as your own quick notes, plus the row design is cleaner (chevrons only on rows that expand).

New features are built from your feedback. Have more ideas? Tap 'Send Feedback' in App or leave a review. Freezer Manager: Tank > Rack > Box hierarchy with custom geometry, 15 freezer item types (antibody, plasmid, lysate, RNA, cDNA, DNA, primer, siRNA, bacterial stock, tissue, serum, protein, peptide, buffer, other), unified map, Print Box Label PDF, mass-freeze flow, barcode scanner. ELISA 4PL Standard Curve calculator: Levenberg-Marquardt nonlinear fit with multi-sample input, named samples, per-row dilution, and a log-axis standard-curve chart. MOI calculator now plate-aware: pick a 6/12/24/48/96-well format and the calculator splits virus + media per well, scales totals across wells, adds an optional master-mix overage, and warns when the titer is too low for your MOI. Lab Handover Pack: multi-page A4 PDF with cover + freezers + cell lines + reagents + protocols + active experiments + plate layouts. One tap to share or print. Voice dictation now stops cleanly during a call or Siri interruption, and clears its draft after a swipe-to-dismiss. Today board respects iOS notification permission with a clear in-app banner if you have notifications turned off. Calculator Log button now captures every input field across the catalogue: TCID50 dilution rows, ELISA replicate mode and asymptote overrides, primer Tm sequence, Bradford standards, Hemocytometer per-quadrant counts, and 9 more.

New features are built from your feedback. Have more ideas? Tap 'Send Feedback' in App or leave a review. v1.7.2 is a quality release: Voice notes are stable. Long voice-to-notebook sessions no longer get stuck or drain the battery. Sessions auto-stop after 90 seconds of silence. Photo Editor: Revert to Original. A new button in the editor toolbar restores the original photo if you don't like an edit. Equipment list: swipe to delete. Plus the status dot is now an icon shape (not just a colour) so it's readable for colourblind users at a glance. Spotlight search is a lot smarter. Notebook entries are now indexed and searchable. Tapping a Spotlight result opens the entity's detail view (not just the parent list). Cold-launching the app from a Spotlight result now reliably navigates to the right place. Hydrogel calculator clarity. The "Stock volume" field is renamed "Stock on hand" with a live caption that tells you immediately whether you have enough. Reagent units cleaned up. The free-text Unit field is replaced with a 13-unit picker. Existing free-text units are normalised on first launch so the Reagent Dosing calculator can find them. Calendar performance. The Today calendar paints instantly even with months of history. Tasks are auto-recorded. Creating, completing, editing, deleting, or bulk-clearing tasks now writes to your auto-recorded Logbook. Apple Watch complication. Fixed a sandbox bug where the watch face complication could freeze on the first timer it ever saw. Dark mode polish. Status pills, accent colours, and the Photo Editor canvas now meet WCAG AA contrast. iPad layout. Reference card grids now use 4/5 columns on iPad instead of 2/3. Accessibility. Sliders are now VoiceOver-adjustable. Calendar reads event types aloud. Many icon-only buttons gained explicit labels. Hardcoded small fonts now scale with Dynamic Type. Virus Stock now supports IU/mL (qPCR) and genome copies/mL titer units. Reliability hardening. Notification permission is rearmed on cold launch, equipment maintenance reminders are bounded, the iCloud-vs-legacy migration no longer wedges silently

One new screen, lots of invisible safety under the hood. NEW: PREVIEW BEFORE IMPORT When you pick a backup, a new screen shows exactly what will happen before anything changes: • How many new cultures, reagents, experiments, and other items would be added • Which existing records would be updated, and what fields would change • How many same-name duplicates would be skipped • Any parse errors or oversized lists Toggle "On duplicate: Skip / Update" and the preview refreshes instantly. Nothing touches your data until you tap Confirm. SAFER DEFAULT FOR SAME-NAME RECORDS A backup containing a "HeLa" row will no longer silently overwrite your real HeLa with someone else's medium or BSL. The default is now Skip, across cell lines, reagents, equipment, virus stocks, protocols, plate layouts, culture templates, recipes, and experiments. Your own round-tripped edits for cultures, vials, lots, and notebook entries continue to apply as before. ALL-OR-NOTHING IMPORTS An import either completes fully or doesn't touch your database at all. If something fails partway through, everything rolls back automatically. No more half-imported state where reagents landed but experiments didn't. ERRORS YOU CAN SEE Now every failure is logged, counted, and shown in the Import Result alert so you can trust what it says. SAFER FILE ROUTING The import picker now checks what's actually inside a file instead of just its name. A script renamed to .zip is rejected with a clear message. A single CSV bigger than 150 MB is refused so the app can't run out of memory mid-import. Thanks for using Cell Culture and Lab Assistant.

New features are built from your feedback. Have more ideas? Tap 'Send Feedback' in App or leave a review. REAGENT LOTS Multiple lots per reagent with lot number, vendor, catalog number, open date, expiry date, remaining fraction, price, and performance notes.
