### 1/5 — App needs some work

*2026-04-02*

This does not work on an IPad. It also needs work when it comes to salt tubs.

### 3/5 — Great until..

*2026-01-07*

Had this for almost a year. One day woke up and it said the PH was low, added soda ash waited, says it went lower. Kept on going the wrong way. Brought a water sample to Leslie’s to test, PH at 8.5. Something is definitely wrong.
