How it works
- Dip your test strip, hold horizontal for 15 seconds.
- Lay flat on a white surface and photograph from straight above.
- Upload above. We detect the strip, sample each pad, and match colour swatches.
- Get a directional read on 7 chemicals + the order to dose and wait.
Honest note: photo-based strip readings are directional. They tell you what's off and roughly how much to add — great for routine pool care. They are not a substitute for lab testing if you suspect a serious water-balance issue. We refund if it doesn't help — reply to your receipt.
