### 5/5 — Great app; want dozenal

*2022-09-11, version 1.0.2*

This is a great app; I would like to see this work in dozenal (base 12)!!

### 1/5 — Can never open it!?!

*2021-10-15, version 1.0.1*

The app looks cool from the pictures above but after down loading it, all it does is shutdown. I am running OS 15.1(it is a beta software version)

My process of trying to open it, click on the icon on my phone and the screen goes black, the icon gets bigger like it is trying to open, then it goes back to the phone screen and never opens.
