NEVER LOSE YOUR REEF DATA AGAIN. Reef Tank Log is the offline-first journal built for saltwater reef keepers. Log your parameters, schedule your dosing, and track your corals - all on your device. No account. No ads. No subscription just to write down a test result. Tired of apps that crash and wipe months of data, or suddenly lock basic logging behind a paywall? This one doesn't. Logging your parameters and backing up your data are free, forever. - TRACK EVERY PARAMETER - Salinity, alkalinity, calcium, magnesium, potassium, nitrate, phosphate, pH and temperature, logged with the exact precision reefers need (yes, salinity to 1.0255). Tag each result with the kit you used - Hanna, Salifert, Red Sea or API. - FIX A BAD READING - Fat-fingered 85 instead of 8.5? Open the reading history from the chart and edit or delete any single point. Your trend line is never stuck with a typo. - SEE THE TREND, NOT JUST THE NUMBER - Clean trend charts with your target range shaded in, so you instantly see when alkalinity is drifting. View 30 days, 90 days, a year, or all of it, with a stability readout for the window. - DOSING DONE RIGHT (Pro) - Schedule alk, calcium, magnesium and trace doses daily, every N days, or on a chosen weekday, with local reminders that fire offline. Tick a dose off in one tap. - IMPORT YOUR ICP LAB RESULTS (Pro) - Your ICP analysis comes back with twenty numbers on it. Import the whole report instead of typing any of them: a PDF, a photo of the printout, or a CSV from Oceamo or Fauna Marin. The app reads the table, converts the units, dates the readings to the day you took the sample, and shows you every value to confirm before a single one is saved. Tested with Oceamo and Fauna Marin. - A REEF-FOCUSED LIVESTOCK JOURNAL - Add corals, fish and inverts by common and scientific name, sorted into SPS, LPS, softies, fish and inverts. Keep a tagged written journal per animal to follow growth, colour and health, and mark anything fragged, sold or lost. - MAINTENANCE AND EQUIPMENT - Log water changes with percentage and cost, skimmer services, glass cleans and media swaps. Keep a list of your lights, pumps, heaters and dosers with install dates and warranty notes. - YOUR DATA STAYS YOURS - Everything is stored locally on your device. Export a full backup to Files, iCloud or Drive anytime, and restore it in one tap. No login that can lock you out. No tracking. No ads. FREE forever: • 1 tank • Unlimited parameter readings • Trend charts and stability • Livestock journal, maintenance and equipment • Full backup and restore Reef Tank Log Pro: • Unlimited tanks • Dose schedules with offline reminders • ICP lab report import - PDF, photo or CSV Logging and backup are always free. Pro is a one-time option too - because we know reefers are done with subscriptions. Built for the hobbyist who treats their reef like the living investment it is.
