Best Summer Ever

There was no guessing with this app and the test strips! I tested it each week took the picture with app and followed the instructions. It was perfect 1 2 3 done. Least amount of stress, money and headache- you have to use this if you have a pool!

Takes the quess work out.

I’m a bit colorblind, especially when the hues are faint. The app scan feature makes it easy. Just make sure you scan it as close to 20 seconds as possible.
