The app was wonderful last year. Worked great, despite the high price. It’s useless though, on an iPhone XS. You open the app, and the screen goes black. All the settings at correct. There’s no trouble shooting, and no way to get in touch with the creator, just a useless faq on the website. If you don’t have an old phone, don’t waste the money.

I used this app for several years and liked it. I recently went from an iPhone 7 to 8. I am no longer able to the app because it does not appear to be accessing the phone’s camera. I only see blackness overlaid with the usual countdown timer.The same thing happens when I try to use the app on my iPad.

This app has too many bugs. For example, on iPhone X the capture timer is erratic and starts counting down twice or more and gets stuck in a loop taking pics and firing off the shutter sound in a loop and I have to stop the app. Also, doesn’t appear to list 5 way test strips, so the results are flaky. I’d like a refund... $9.99 is not worth it.

I always had to have my daughter help me Visually match the colors when testing my spa. This app makes the process so easy. I like the reminder too. Thanks AquaScan! :-)
