Offline aquarium log

TankTrace

Know what changed, what is due, and whether every tank is staying steady — entirely offline.

Keep aquarium water readings, safe ranges, maintenance, livestock, and care history together in a private offline log.

iPhone, iPad

Local-first

Water quality at a glance

Record custom parameters and safe ranges, then see clear in-range, below-range, or above-range status with trends.

Schedule recurring water changes, tests, and filter care with due dates and a complete history.

Aquariums, livestock, and notes stay on your device; export standards-compliant CSV only when you choose.
