About
Tankwell is a fast, fully offline aquarium water change reminder for anyone keeping one tank or a whole fish room. No accounts, no cloud sync, no clutter — just a clean list of your tanks and exactly when each one needs attention. Most tank-tracking apps bury the one thing you actually open them for — "is it time yet?" — under logs, journals, and social feeds. Tankwell strips that away: add a tank in two taps, set a water-change interval, and get a local reminder when it's due. Logging a completed change takes one tap and instantly resets the countdown. WHY TANKWELL • One-tap logging — no forms, no friction • Fully offline — your tank data never leaves your phone • No account, no sign-in, no ads • Built for aquarists managing multiple tanks at once INCLUDED • Track up to 2 tanks with water-change reminders • One-tap logging with automatic countdown reset • Local notifications so you never forget • Full change history per tank TANKWELL PRO (one-time purchase) • Unlimited tanks • Filter change, water test, and fertilizer dosing reminders • Custom reminder time per task • Export full history as CSV Whether you run a single betta bowl or a fish room full of reef and cichlid tanks, Tankwell keeps every water change on schedule without ever asking for your data.
