pool test strip scanner

Although the AquaChek 7 bottle clearly states to not shake off the excess water from the strip, the water droplets will cause the camera to get a false reading. I recommend shaking off the water at around 12 seconds of the 15 min countdown so that you can capture the image at the right time.

Cyanuric acid shows 0, even on retest, results differ each time.

Would be great to attach a name to the saved strip reading

To make it work with AquaCheck7 strip you need to take the test strip out of the water colored side up with water staying on the strip and wait 15 seconds per instructions. After I started doing it right I completely agree with strip reading of the app. Even if you disagree, it gives the baseline. Super! Add the reading visualization with charts and developer can start charging for it.

I always have trouble identifying which color is closest to the one on the chart. The app quickly matches the color and gives you the appropriate results. You can also save the results which is very useful. I wish I knew about this app sooner. It’s well worth the $1.99.

The developer fixed the save/crash issue about a year ago. I use this app all the time. Whatever accuracy issues it may have I blame on the test strips themselves—I always re-test my ph and sanitizer levels with a liquid kit and find that while the app is right on with the strip colors, the strip colors often vary from the liquid kit results. Perhaps when the strips get old they lose accuracy. But the app is great, much easier than trying to eyeball stuff from a color chart.

Primarily on the Cyanuric acid. No matter the color, it scans as brown or ‘0’.

I bought this app because I have a hard time deciding between 2 options on the test strips but this scanner read it way off and rescanning the same strip gave way different results.

Would be good to have a choice of type of pool: vinyl, fiberglass, gunite. So far I like it, how accurate it is , I'm not sure. Probably better than MY eye.

Maybe with practice it will get better. I will update after longer use.
