Can’t Delete Entries

Not a bad app but has a limited database. You can add your own caffeine drinks however.

Biggest issue is you can’t delete an entry once added. So if you make a mistake your are stuck. 😕

Response from developer

Hey I'm glad you tried my app. I am working on making the drink selection more expansive. To delete an entry scroll down on the main dashboard to the drink in the 'Today's activity' section and tap on the entry. Tap 'delete' to delete the entry. I am working on some UI improvements that will make deleting easier. Thank you for giving me feedback on my app.

Useless

There’s nothing useful about the app. Bad UI. Developer is spamming Reddit subs that have nothing to do with this content.
