## What is Aquarium Coach?

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 from common API, Tetra, Red Sea, JNW, and Sera test strips. 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.
    
  Plus all the basics:
  • Multi-tank support — freshwater, planted, saltwater, reef, brackish
  • Livestock and equipment logs
  • Water-change, filter-cleaning, and dosing reminders
  • 30-day and 90-day trend charts for every parameter
  • PDF export to share with your local fish store or vet
  • Sign in with Apple syncs across iPhone and iPad
  • Family Sharing — one Pro subscription covers up to 6 household members
  
  Free tier: 3 test-strip scans + 2 tank-health scans per calendar month. Pro ($4.99/mo or $39.99/yr) raises the cap to 50 AI scans per month and unlocks PDF reports, long-range trend charts, and Family Sharing. 
  
  Privacy: photos transit through our servers for the AI scan only and are never stored beyond a short-lived diagnostic log (auto-purged after 30 days). We don't run ads, don't track you, and don't sell your data to anyone. 
  
  Aquarium Coach is informational and not a substitute for veterinary care. For complex fish-health issues, please consult a vet or experienced fishkeeper.
  
  Built by an aquarist for aquarists.

## Version history (last 5 releases)

### 1.4.0 — 2026-08-11

Get to your first reading faster.

  • Scan straight away — tap "Scan a test strip" the moment you open the app.
    There's no tank to set up first; we'll start one for you, and you can name
    it once you've seen your readings.
  • A shorter welcome — one screen instead of three, and you only sign in when
    you save your first scan.
  • Free tier is now 3 test-strip scans a month (tank-health scans stay at 2).
    Pro raises the cap to 50 AI scans a month.

### 1.3.0 — 2026-07-07

• Alerts you'll actually see — out-of-range readings and recurring reminders now fire dependably, so you never miss a water change.
  • Sharper test-strip reading — upgraded AI, with carbonate hardness (KH) now included in alerts.
  • Smoother sign-in — no more surprise sign-outs on shaky Wi-Fi.
  • Cleaner goodbyes — deleting your account now fully removes your data.

### 1.2.0 — 2026-06-16

### 1.1.0 — 2026-06-03
