Meh

Has to be open. Not in background. Just not functional in my world.

Doesn’t work

Update: app is charging my bank account even though I canceled my subscription and removed the app. I am going to have to contact my bank now. FURIOUS

I paid and ended up canceling after about a week. Only a tiny beeping sound happens after setting the alarm. Yes I knew how it works and how to set the alarm tone and volume. Total waste of my money I would like my money back, please…
