Everything in the logbook
Eight pieces of one loop: log the reading, get reminded before the next task is overdue, then read the trend instead of the number.
Water Test Log Free
pH, ammonia, nitrite, nitrate, temperature and any custom reading — attached to the tank it came from, dated, and searchable.
Learn more →Maintenance Reminders Free
Water changes, filter cleaning, siphoning, top-offs and dosing — scheduled per tank, with overdue work surfaced on the Today screen.
Learn more →Feeding Log Free
One-tap feeding entries per tank, so “did I already feed them?” stops being a guess — and so does overfeeding.
Learn more →Multi-Tank Dashboard Pro
Track multiple tanks with separate logs, schedules and parameters — plus an All Tanks overview of what needs attention today.
Learn more →Water Trends Pro
7, 30 and 90-day charts for pH, nitrate, temperature and every other parameter you log — one line per tank.
Learn more →CSV Export Pro
Export water tests and maintenance history to CSV at any time — for backup, spreadsheets, or your own analysis.
Learn more →Turtle Tank Log Free
Turtle tanks are messy, heavily filtered and water-changed far more often. Log water parameters, siphoning and basking setup in the same place.
Learn more →Offline & Account-Free Free
Every log is written to your device. No sign-up, no email, no analytics — the App Store privacy label says data not collected.
Learn more →One log, every tank, no subscription
Free for one tank. Pro is $3.99 once — multi-tank, trends and CSV export, forever.
