Free aquarium maintenance app for Android and iPhone
App-aquatic runs the same app on Google Play (Android) and the App Store (iPhone & iPad). Use it to log water tests from strip scans, browse fish and plants, and (with a trial) run tank dashboards and care reminders. The strip scanner and database stay free forever; premium tools are optional after a free trial.
What you get
A serious freshwater toolkit — with strip scanning and species lookup you keep for good.
Included forever
Strip scanner + fish & plant database
Free for life: offline test strip scanning, logging from scans, kit calibration you own, and the complete fish & plant reference library. Use them after trial ends, after cancel — still free. Still no ads on these features.
Why hobbyists stay
One subscription unlocks dashboards, trends, AI scans, simulator, and Caretaker — without ad spam. Built for people who actually keep tanks, not for data harvesters.
Who it is for
Anyone running freshwater who wants reads they can trust, IDs they can verify, and a place that does not bait-and-switch the basics behind a paywall.
After the trial
Seven days to stress-test the premium layer. Then subscribe to keep dashboards, history, scans, simulator, reminders, and multi-tank. The strip scanner and fish & plant database do not disappear when the trial ends.
