So helpful 🙌🏼

I am a true coffee addict, especially because I live in the Pacific Northwest. This app has helped me explore all the different ways to enjoy that special morning cup. It also helps me keep track of what I have enjoyed the most so I can recreate that magical moment accurately every time.

Oh my LANTA!!! This app is better than sliced gluten free toast with vegan butter!!! I can’t even. Like how did I make coffee before this FANTASTIC AND REVOLUTIONARY APP?!? Please make one for toast in a toaster and butter churning; I would legit die! So the best!!!!!!!

Useless - And unusable

No alarm. And the timer pauses as soon as the screen goes to sleep mode or the app is in the background. A total waste of good 90 cents.

Developer Response ,

Hi. Sorry that this was missing. The app is now updated and will continue the timer in the background as well as display timer notifications when the app is closed or the screen is locked. Please give us another try after the update and let us know if everything is working as it should.
