The only reef app fully built for SPS, LPS, and mixed reef keepers worldwide. WHAT MAKES CORALYTIC DIFFERENT Most aquarium apps are clunky spreadsheets. Coralytic is built like a 2026 iOS app should be — beautiful dark interface, native Swift, instant sync across iPhone and iPad.

Track every coral, catch water swings early, and never miss a treatment. Acro Reef is a private, offline reef tank tracker built for serious coral keepers. Follow growth with photo timelines, monitor alkalinity and other water parameters, schedule recurring care, and track treatment outcomes in one place. Every Acropora, Stylophora, and Montipora gets its own record — not a line in a spreadsheet. Track where you got it, what you paid, and how it's growing. Compare today's photo against last month's, mark affected tissue directly on photos, and follow treatments, outcomes, and recurrences in a unified case timeline. WATER TRENDS THAT MATTER Daily alkalinity, calcium, magnesium, nitrate, phosphate, salinity, temperature, and pH readings stop being numbers and start being a line. Customize targets and swing thresholds, add parameters such as ORP or potassium, enter a batch of tests at once, and see tank events directly on the chart. REEF CARE, ON SCHEDULE Create recurring water tests, water changes, dosing, cleaning, and equipment tasks with local reminders. Estimate 14-day ALK, calcium, and magnesium consumption, calculate a dose, and keep a chronological tank-event log. TREATMENT SCHEDULING, DONE RIGHT Built-in protocols for the dips and tank treatments serious SPS keepers actually use — Bayer Dip (AEFW), Interceptor (Red Bugs), Levamisole (AEFW), Peroxide Dip (algae/cyano), Fluconazole (Bryopsis). Dose-progress pips track which doses you actually completed, not just what was scheduled. Today-screen reminders surface what's due. ON-DEVICE, NO ACCOUNTS Your reef data lives on your device. No cloud account to sign up for, no analytics, no telemetry, no tracking. Create a complete backup containing tanks, corals, photos, readings, care schedules, and preferences, then restore it when needed. Acro adapts to both iPhone and iPad. FREE TO TRY Free tier: track up to 2 corals, keep 30 days of water history, and store up to 3 photos per coral. Treatment logging is unlimited so new SPS keepers can get help with the protocols immediately. ACRO PRO — ONE-TIME PURCHASE Unlock unlimited corals, full water history, unlimited photos per coral, and CSV export. Buy once. Yours forever. No subscription, no recurring charge. IMPORTANT — TREATMENT DISCLAIMER Treatment protocols, dosages, and durations shown in Acro are hobbyist references compiled from public reefkeeping sources. They are not veterinary advice. Always verify dosing with the chemical's product label and your own research before use; some compounds (e.g. levamisole, fluconazole, imidacloprid-based dips) are hazardous to invertebrates, pets, and humans if misused. Acro runs on iPhone and iPad. Requires iOS / iPadOS 17 or later.
