What's New in Version 1.5.2 This update improves data sync and fixes several bugs for a smoother experience. • Faster sync: Your data syncs to iCloud immediately after saving • Recent measurements protected: Latest readings won't be overwritten by older data • Deleted tanks stay deleted: Removed tanks won't reappear after syncing • No duplicate dosing schedules: Editing a dose updates the existing schedule • Delete maintenance tasks: Remove tasks directly from the Maintenance screen • Better iCloud sign-in: More reliable sign-in across all your devices Thank you for using Reef Trak!

This update focuses on safety, accuracy, and reliability where it matters most. We fixed critical dosing calculation issues affecting several products to ensure maintenance doses are safe and accurate, even on large systems. Dosing schedules now behave correctly when edited or deleted, preventing duplicate reminders and leftover tasks. Cleanup and sync handling were improved to keep your data consistent across devices. These changes make Reef Trak more dependable for daily reef management and long term stability.

We are back with our biggest update since September. We have spent the last few months rebuilding our core data infrastructure to bring you massive improvements in performance and stability. NEW: AI Insight Export We have retired the internal on-device chatbot to give you more power and flexibility. We want you to have access to the smartest models available without being limited by an internal tool. We have introduced the AI Insight Export wizard. This feature compiles a comprehensive snapshot of your tank, including: • Current water parameters and 7-day trends (rising, falling, or stable) • Active dosing regimens and product schedules • Complete livestock lists, including recent additions and removals • Activity logs and maintenance history The app formats this data into a structured "Perfect Prompt" that you can copy and paste into your preferred external AI tool or Large Language Model. This allows you to get husbandry advice, troubleshooting help, and compatibility assessments based on your specific tank data. Unified Catalog We have completely rebuilt our biological database to ensure data integrity. • The catalog now contains 1,026 verified fish, 271 corals, and 81 invertebrates. • We resolved specific data conflicts where different fish shared duplicate identifiers. • Every species now has a unique ID that will sync correctly across your devices. Visual Overhaul We have significantly improved the browsing experience for the reference library. • Added 334 new high-quality images for corals and invertebrates. • Replaced generic animated placeholders with real photography in the Asset Catalog. • Improved image loading logic to ensure faster scrolling performance. Performance and Stability • Rewrote the database seeding infrastructure to prevent conflicts during large data updates. • Improved CloudKit syncing logic to handle bulk data operations more safely. • Fixed an issue that could cause infinite saving loops during the initial database seed. • Optimized the export format to ensure better readability when sharing reports. Thank you for your continued support as we continue to improve the Reef Trak experience.

What’s New in Version 1.4.1 This release brings the biggest upgrade yet to BlenAI, the built-in reefing assistant designed to work hand in hand with your tank data. BlenAI is now fully connected with all of the information you store in ReefTrak, giving you personalized guidance that matches your reef’s actual conditions. Whether you are asking about your water parameters, dosing, or livestock compatibility, BlenAI now draws directly from your saved logs and history to provide answers that are accurate, relevant, and actionable. A major part of this update comes from the feedback submitted by ReefTrak users through the reporting tool. That feedback has helped refine how BlenAI processes tank data, making it significantly more powerful and precise. Highlights of this update: • Full data integration – BlenAI can now access your parameters, livestock, dosing logs, and maintenance history to tailor its answers to your reef. • On-device processing – BlenAI continues to run entirely on your device, keeping your data private and never transmitting it to the internet. • Improved accuracy – Refined responses based on real-world user feedback from the built-in reporting tool. • Smarter insights – Advice that considers your unique history rather than generic recommendations. • Faster performance – Optimizations across the app to make BlenAI respond more quickly and reliably. • UI refinements – Cleaner navigation, streamlined dashboards, and performance improvements throughout the app. Examples of what BlenAI can now do in 1.4.1: • Evaluate your phosphate, nitrate, or alkalinity levels against your own custom ranges. • Suggest adjustments to dosing schedules using the products you have already logged. • Provide compatibility checks between new livestock and your existing inhabitants. • Reference your ICP test results to point out long-term nutrient or trace element trends. • Remind you of missed or upcoming maintenance tasks and explain their impact on stability. This version marks a turning point for ReefTrak. Your logs are no longer just stored records, but a living knowledge base that BlenAI can use to guide you with clarity and confidence. As always, ReefTrak remains focused on privacy, accuracy, and practical reef keeping. With version 1.4.1, your reef’s story becomes more than data. It becomes advice you can trust, right at your fingertips. Love Your Reef. Trak It.

What’s New in Version 1.4 This major update merges everything planned for 1.3.3 and adds a wave of new improvements. ReefTrak is now faster, smarter, and more connected to your reef than ever. BlenAI – Your Reef’s AI Buddy BlenAI is now fully integrated into ReefTrak. It connects directly with your tanks, parameters, and maintenance history to give advice tailored to your reef. The more you log, the smarter it becomes, offering insights, explanations, and suggestions that match your exact setup. Premium Tier ReefTrak Premium is here.

ReefTrak 1.2.2 Changelog: The Great Sync Surge WHAT'S NEW FULL iCLOUD SYNC IS HERE (AND FREE!) After weeks of rebuilding from the ground up, ReefTrak now supports full iCloud syncing for Tanks, Parameters, Coral, and Fish. Whether you're logging your test results at home or checking in from work, your reef data stays perfectly in sync across devices. It's fast, reliable, and included at no extra cost in the free version of the app. We've designed sync to be smart. It processes your data in stages, skips over anything that looks off instead of crashing, and keeps everything intact even during complex merges. It's handled under the hood, so you don't have to think about it—just track your reef with confidence. ROCK SOLID STABILITY This release puts a massive emphasis on one thing: STABILITY. We've tackled a long list of bugs and rare crash scenarios to make the app smoother, faster, and more resilient than ever. If you've experienced unexpected crashes or sync issues in the past, this update is for you. The app now handles bad data more gracefully, avoids race conditions in sync, and makes smarter decisions when resolving data conflicts. The result? A much more stable, much more predictable experience. If anything feels fishy, reach out through the built-in support form—we read everything. SMARTER PROGRESS + SYNC FEEDBACK The sync engine now includes real-time progress reporting, detailed error logs (behind the scenes), and safer batch processing. It won’t hang at 2% anymore, and you’ll see clear messages when uploads and downloads complete. Even if one record fails, the rest will continue. Think of it as “bulletproof syncing,” now with visible feedback. PREPARING FOR JUNE: FREE & PAID TIERS Starting in June, ReefTrak will switch to a paid model—but not for everything. The core tracking experience will **always** remain free. The FREE tier will continue to include: - Unlimited Tanks - Unlimited Water Parameter Logging - Interactive Charts & Logs - iCloud Sync The PAID tier will unlock advanced features and premium tools to support serious reefers and future expansions. As part of the launch, we’ll be offering a **limited-time $9.99 lifetime license** for early supporters. CLOSING THOUGHTS This update represents a massive leap forward. Dozens of internal improvements. Cleaner code. Smarter syncing. Fewer crashes. Faster logging. If ReefTrak has helped you on your reefing journey, we’d love to hear from you. And if anything breaks or acts weird, we want to fix it—just tap the support button in the app and let us know. Thank you for helping make ReefTrak the tool we always wished we had. We’re just getting started. - Joe

ReefTrak Patch Notes – April 1 to April 16, 2025 A steady tide of progress Major Improvements to Cloud Sync Stability Over the past few weeks, we’ve focused heavily on improving the iCloud sync system. Syncing parameters and tanks is now working more reliably across devices. Fish, corals, and maintenance data are syncing in most cases, but we are still working through a few edge cases where data may not download correctly. All data is still securely stored in your personal iCloud account, and we’re continuing to improve how consistently it’s retrieved. To help ensure your data syncs correctly, we’ve added a manual sync option in the toolbar—though in most cases, you shouldn’t need it. Visual Maintenance Overhaul The Maintenance tab has received a lot of love: Green checkmarks now appear next to completed tasks Calendar view displays daily, weekly, monthly, and quarterly tasks accurately Progress bars now show completion ratios correctly Task counts include completed entries for better tracking Custom task support improved with smarter filtering and debug logging Sync Progress Bars + Robust Logging Syncing now shows percentage-based progress bars throughout the process, including: Visual sync tracking from 1% to 100% Progress reporting for each step of the parameter sync More accurate failure messages and retry mechanisms for CloudKit errors Resolved issues with duplicate records causing sync to hang Smarter Sync Logic & Concurrency Fixes We refactored large parts of the sync engine: Smarter batch processing for parameters, with reduced race conditions Improved actor isolation and concurrency handling for smoother operations Better error handling and retry logic for all CloudKit interactions Conflict resolution and deduplication systems now better preserve data integrity across multiple devices Calendar Task Display Improvements Custom, daily, and recurring maintenance tasks now show up reliably on their assigned days, with better logic for task recurrence and display. Whether you run weekly water changes or quarterly equipment checks, the app is now better at keeping them visible and organized. Additional Changes ICP date handling and result display refined Improved UI feedback for task completions and errors Tank image syncing bugs resolved Detailed logging added for all key sync functions Performance optimizations across the board New: Submit Feedback Directly From the App Have an issue or suggestion? You can now send feedback straight to me using the new “Submit Feedback” button in the main toolbar. This sends an email that includes basic device information to help troubleshoot—but nothing personally identifiable is collected or stored. Coming Soon: Subscription & Lifetime Unlock ReefTrak will remain free for the next month while we finalize and test subscription handling. On or around June 1st, we’ll re-enable purchasing options: Lifetime unlock: $19 Monthly subscription: $2.99 This helps support ongoing development and server costs, especially as features continue to expand. Thanks for sticking with ReefTrak as we improve reliability and usability. Your feedback makes all the difference. – Joe

Temporary full access to Premium features While subscriptions are still propagating in the live App Store environment, all users will temporarily receive Premium access by default.
