AquaLog: Aquarium Water Tests
Fish Tank Log & Reminders
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
See at a glance which tank needs attention. Log a water test in seconds and spot problems before your fish do. Your first tank is free, with every feature.
AquaLog shows you which tank needs attention — and what to do about it.
Log water tests in seconds, see every reading against its safe range, and get reminded before a water change is overdue. Freshwater, planted, saltwater or reef.
SEE WHAT NEEDS YOU
• One home screen for all your tanks: problems first, then what's due, then the stable ones
• Out-of-range readings come with a plain explanation and a suggested next step
LOG A TEST IN SECONDS
• Tap a value instead of typing — your last result is right there
• pH, ammonia, nitrite, nitrate, temperature, KH, GH, salinity, calcium, magnesium and phosphate
SPOT PROBLEMS EARLY
• Every chart shows the safe range as a band of water, so a bad trend stands out
• Water changes are marked on the chart, so you can see what they did
STAY ON SCHEDULE
• Reminders for water changes, feeding and cleaning
• Keep track of livestock, equipment, food and maintenance for each tank
BUILT FOR KEEPERS
• Dark mode first, with a light mode
• iPhone and iPad, synced with iCloud
• No ads, no account
