User reviews

Broken

I just told the app that I took five shots of hard liquor. 30 minutes later, it reported my BAC as 0.004. Other sources indicate my level would be far higher, 0.09. I trusted this app for a long time, but this version is broken.

Does exactly what it should

Great app that’s simple to use. Easy to enter drinks, volumes and abv. Easy to check history of entries and edit or delete them.

What happened?

This app was great for years. I found it to be highly accurate and easy to use. This is within reason of course because there are several variables at play from person to person.
I used this while ordered to carry a state calibrated breathalyzer. And it was accurate within an hour.
However, after the newest update, the app no longer recognizes drinks after midnight as being in the same “graph”. Actually, for some reason; it now moves it to the previous day as future dates aren’t available which makes absolutely no sense. It didn’t used to do this.
Proceed with caution.

Fell off -unusable

Worked great for years but they’ve stopped updating and it’s no longer useable

No Longer Works

Perhaps the latest iOS is what finally broke this long-abandoned app.
