Common questions

How does the test strip scanner work?

Hold a freshly-used wet strip in the camera frame. We send the photo to Anthropic's Claude vision API, which reads the color pads against the brand's reference chart and returns numeric values for each parameter. You see the AI's reading plus a confidence score — you can override any value before saving. The photo is auto-purged from our servers after 30 days.

Which test strips are supported?

API 5-in-1, API 6-in-1, Tetra EasyStrips, Red Sea Reef Foundation Pro, JNW Direct, and Sera 6-in-1 are tested and known to work well. Other paper strips usually still work — the model handles them generically. Liquid test kits (drop-based) are not supported.

What does Pro unlock?

• Up to 50 AI scans per calendar month (free tier is 5 strip + 2 tank-health scans)
• PDF reports you can share with your local fish store or vet
• Long-range parameter trend charts (30-day, 90-day, 1-year)
• Family Sharing — one Pro subscription covers up to 6 household members

Pro is $4.99/month or $39.99/year. Both auto-renew until cancelled in Settings → Apple ID → Subscriptions.

How do I cancel my subscription?

Open the iOS Settings app → tap your name at the top → Subscriptions → tap Aquarium Coach Pro → Cancel Subscription. Your Pro features stay active until the end of the current billing period. Apple — not Aquarium Coach — handles the cancellation and any refund eligibility.

I bought Pro but my other device still says "Free"

Open the Aquarium Coach app, tap the sparkle icon on the Home tab, then tap Restore Purchases at the bottom of the paywall. Make sure both devices are signed into the same Apple ID. Family Sharing members need to enable it for the subscription in Settings → Family.

How accurate is the AI scan?

Strip scans are typically within one color-pad step on common brands in good lighting. Tank-health scans are guidance, not diagnosis. We always show a confidence score with each reading — if it's low, the lighting, focus, or strip orientation is probably the cause. Aquarium Coach is informational; for serious fish-health issues, please consult a vet or experienced fishkeeper.
