ReefLog helps you read it. Track alkalinity, calcium, magnesium, and 10 more parameters with beautiful trend graphs, target range indicators, and instant status dashboards. Built exclusively for saltwater reef aquariums -- not freshwater, not ponds, not general "aquarium management." No subscription. No account required. No ads. Pay once, own it forever. --- LOG WATER TESTS IN SECONDS --- Tap, enter your numbers, done. ReefLog is designed for speed because you're logging parameters at your tank, not sitting at a desk. Every parameter a reef keeper tracks is built in with the correct units: - Alkalinity (dKH, meq/L, ppm CaCO3) - Calcium (ppm) - Magnesium (ppm) - Salinity (ppt, SG, PSU) - pH - Temperature (F / C) - Nitrate (ppm) - Phosphate (ppm, ppb) - Ammonia, Nitrite, Potassium, Strontium, Iodine --- SEE TRENDS BEFORE PROBLEMS START --- Beautiful trend graphs show your parameter history with ideal target ranges highlighted. See at a glance whether your alkalinity is drifting, whether your calcium consumption is increasing, or whether that new dosing schedule is actually working. Compare multiple parameters on a single chart to spot correlations. Spot problems before your coral does. --- DASHBOARD WITH STATUS AT A GLANCE --- Every parameter displays a color-coded status indicator -- green when in range, yellow when drifting, red when out of range. Mini sparkline graphs on every card show recent trends without opening a single chart. Know your tank's health the moment you open the app. --- TRACK EVERY TANK YOU RUN --- Display tank, frag tank, quarantine tank -- each one gets its own dashboard, its own history, its own target ranges, its own trend lines. Support for up to 10 tanks. Switch between them instantly with a single tap. --- YOUR DATA, YOUR DEVICE --- No account required. No login screens. No server dependency. Your data lives on your device. You will never lose years of parameter history because of a server outage or a broken password reset. Export to CSV anytime -- your data is always yours. Perfect for hobbyists who also maintain spreadsheets or want to run their own analysis. --- BUILT BY A REEFER, FOR REEFERS --- ReefLog speaks your language. Alk in dKH or meq/L. Calcium in ppm. Salinity in ppt or specific gravity. Target ranges based on proven reef chemistry, not generic aquarium values. Customizable ranges per tank because your SPS-dominant display has different targets than your quarantine tank. Set test reminders so you never miss a weekly alk check. Dark mode that looks great at 11pm when you're doing your evening tank check. --- WHAT MAKES REEFLOG DIFFERENT --- - Reef-specific from day one (not a general aquarium app) - Modern, native iOS design (not a 2012 UI) - Local-first data storage (no account, no data loss) - Focused on parameters (does one thing exceptionally well) - One-time purchase (no subscription fatigue) - Active developer who actually responds to feedback --- DESIGNED FOR SERIOUS REEF KEEPERS --- If you're testing alk, calcium, and magnesium every week -- and then writing the numbers on a sticky note or burying them in a spreadsheet -- you already know you need a better system. ReefLog is the tool you've been looking for. One-time purchase. No subscription. No ads. No account required. Your reef deserves better than a spreadsheet. ## ReefLog Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/42/50/13/425013f8-69d5-0ff8-ba8e-da7dadba0567/01-dashboard-hero-1320x2868.png/1320x2868.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/c0/23/c8/c023c89c-2824-93ec-20d3-57fc71b26ce4/02-graphs-trend-1320x2868.png/1320x2868.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/94/71/06/947106ad-66a6-874c-6e3b-45217ef348fe/03-logtest-1320x2868.png/1320x2868.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/64/a1/f8/64a1f822-97fc-332c-cd85-fccad918106e/04-multitank-1320x2868.png/1320x2868.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/91/50/3c/91503c5e-971d-8cf9-0b81-c51219ac4222/05-export-1320x2868.png/1320x2868.png) ## ReefLog Available In - [Australia](https://apptail.io/app/reeflog-water-parameters-aHjz/australia) - [Finland](https://apptail.io/app/reeflog-water-parameters-aHjz/finland) - [Norway](https://apptail.io/app/reeflog-water-parameters-aHjz/norway) - [Sweden](https://apptail.io/app/reeflog-water-parameters-aHjz/sweden) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
