Update Issue

The app was working ok until two days ago after I updated it. Now all of my info is sitting in the pending area and it will not go through and I keep getting errors. I also am not able to use the “contact us” section on the app for the reporting the issue as I am getting errors .

Very Buggy/Unusable

This app is a great idea and comes from a book supposedly written by the app creator, that has some really good ideas and concepts. The app, however, doesn't generate reports. You get error codes instead.

There's also no way to access or download the data. Hence, no workaround. On top of that, about 60 days worth of data just got deleted, going by my "streak" which just reset to 0, despite my using the app daily for about half a year.

You'd think the doctor might spend a fraction of his royalties on getting a proper app made.

Glitchy

Recorded all info for 15 day baseline and it was unable to upload information - will be moving on to something else. Do appreciate the blog info but the app doesn’t function.
