Aquarium Coach: Test Strip AI
Scan strips. Save your fish.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Point your camera at a test strip for instant pH, ammonia & nitrate readings. Pick your tank type in one tap, then scan. No setup forms. Free to start.
Aquarium Coach turns your iPhone camera into the two tools every aquarist
actually needs:
• Test Strip Reader — Hold a wet strip in the camera frame. The app reads
pH, ammonia, nitrite, nitrate, GH, KH, alkalinity and other parameters.
It is calibrated for API, Tetra EasyStrips and Red Sea test strips, and
auto-detects other brands. You see the AI's reading and confidence —
adjust if it's off, then save with one tap. No more squinting at color
charts in bad light.
• Tank Health Scan — Snap a photo of your tank. AI flags algae types
(green, BBA, hair, cyano), fish stress signs, plant deficiencies, and
equipment issues. You get a short summary and concrete action items, not
generic advice.
Free for everyone:
• 3 test-strip scans + 2 tank-health scans per calendar month
• Multi-tank support — freshwater, planted, saltwater, reef, brackish
• Livestock and equipment logs
• Water-change, filter-cleaning, and dosing reminders
• Your tanks and test history sync through your iCloud account across
iPhone and iPad
Aquarium Coach Pro ($4.99/mo or $39.99/yr) adds:
• Up to 50 AI scans per calendar month, test-strip and tank-health
combined, with a maximum of 10 scans per day. Scans already used earlier
in the month count toward the 50.
• 30-day and 90-day trend charts for every parameter
• PDF reports to share with your local fish store or vet
• Family Sharing — share your Pro subscription with up to five family
members

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Smoother scans and more dependable reminders.
• First scan asks one question: freshwater, saltwater or reef, so your readings are judged against the right ranges.
• Your AI result is safe: closing the review screen now asks before discarding a scan you've already used.
• Clearer scan limits: Pro shows its 10-a-day and 50-a-month allowance, and the remaining-scans count updates after every scan.
• Scans on slow connections get more time before giving up, and a scan that can't read your strip no longer counts against your free scans.
• Reminders keep firing on schedule even if you don't open the app.
• Saved tank-health scans keep their findings in your Log and no longer hide your latest strip readings.
• Trend charts show KH and GH in the same units as their target range.
• If something can't be saved, you now see a message instead of losing the change.
• Restore Purchases tells you when you need to sign in first.
• Better VoiceOver labels on reading fields, and the camera works in iPad landscape.
