Store description excerpt

Stablereef is a fast, offline-first water log for saltwater and reef aquariums. Unlimited logging, reminders, trends, export — and CSV import to bring in years of history from a spreadsheet or another app. All free. No account, no cloud, and no paywall in your core loop, ever. SWITCHING APPS? BRING YOUR DATA (FREE CSV IMPORT) Tired of loggers that lock basic features behind a subscription — or of hand-typing into a spreadsheet? Import your existing history from any CSV: column mapping with automatic detection, unit conversion (dKH/meq-L, °F/°C, SG/ppt), a preview before anything is written, and a clear report of exactly what came in. Import is free forever — walking in with your own data should never cost money. THE ANTI-SWING WARNING Corals don't die from a number — they die from the swing. The moment you save a reading, Stablereef compares it to your last value and flags any change that jumps outside your safe band: "Alk up 0.8 dKH since last test." You see the risky swing immediately, while you're still standing at the tank — not three charts later. (Reference only; stability bands are tunable, and husbandry decisions are yours.) LOG A FULL TEST IN ABOUT 30 SECONDS Big number pad, last-value prefill, and a grid you control — pin your most-used parameters on top and hide the ones you don't track. Track Alkalinity, Calcium, Magnesium, Nitrate, Phosphate, Salinity, pH and Temperature, in the units you actually use: dKH or meq/L, °C or °F, ppt or specific gravity. No spreadsheet. No second job. SEE THE TREND, NOT JUST THE NUMBER 7 / 30 / 90-day trend graphs with a shaded stability band, so you can tell drift from noise at a glance and catch a problem before it becomes a crash. YOUR DATA IS YOURS — WE DON'T HOLD IT HOSTAGE Free CSV and JSON export, anytime, no paywall. Automatic local backups. Everything works 100% offline. No account to create, no cloud to depend on. Your readings stay on your device; anonymous usage stats help us improve, and you can turn them off anytime in Settings. If you ever want your years of history out, it's one tap. QUIET REMINDERS Local notifications for dosing and testing — so you don't drift on the days you forget. Reminders are free, never behind a paywall. THE "LESS" PHILOSOPHY No livestock encyclopedia. No marketplace. No social feed. No clutter. Stablereef does one thing — watch your tank's stability — and tries to do it better than apps that do ten things. If you've ever felt your aquarium app was more interested in selling you fish than keeping your reef alive, this is the opposite. FREE FOREVER, CORE LOOP INTACT Unlimited logging, anti-swing warnings, trend graphs, reminders, import, and export are free. No subscription, and no paywall in the middle of your core loop — ever. PRIVACY No account. No cloud. No ads, no cross-app tracking. Your reef data never leaves your device — the only thing we collect is anonymous usage counts, with no account, no personal data and no IP address, and you can switch tha
