TankRoutine: Aquarium Care

Know what's due, log what you did, and follow your water tests. Aquarium reminders, tank photos and Home Screen widgets, with no account required.

Know when your aquarium needs attention and keep a clear record of what you did. TankRoutine brings water tests, maintenance reminders and tank history together on iPhone and iPad.

KEEP UP WITH TANK CARE See what is due now and what is scheduled next. Set reminders for water changes, glass cleaning, filter cleaning and plant trimming. Reschedule a task or skip an occurrence without recording maintenance you did not do.

RECORD ONLY WHAT YOU TESTED Enter pH, total ammonia nitrogen (TAN), nitrite, nitrate and temperature in one session. Leave untested values blank. Switch between Celsius and Fahrenheit while entering temperature, and review your results after saving.

MAKE YOUR HISTORY EASIER TO READ Add a photo and details for each tank. Follow water test trends, review past maintenance and compare readings with target ranges you set. Color indicators help you see which recorded values fall outside your targets.

CHECK YOUR HOME SCREEN Medium widgets show your most recently active tank, its photo and recent readings. Large widgets also show due maintenance or upcoming plans. Widget readings are saved records, not live water measurements.

KEEP YOUR RECORDS WITH YOU Record tests and maintenance offline without creating an account. Export a full backup to iCloud Drive using Files, then select that backup to restore it on a device. Backups are manual; records do not sync automatically. Choose liters or US gallons and Celsius or Fahrenheit.

START WITH ONE TANK Start free with one active tank, including water test logging, single-tank maintenance, reminders, trends and full backups.

MORE TANKS, LESS REPEATED WORK An optional TankRoutine Pro one-time purchase unlocks unlimited active tanks, maintenance rounds across tanks, custom layouts for the five supported test fields, tank trend comparisons and CSV export. No subscription.

Built for everyday aquarium record keeping. Target ranges are user controlled and should suit the animals you keep. TankRoutine records your observations; it does not measure water or diagnose fish health.
