## Auth. Reviews in Vereinigte Staaten

### ***** "Easy to use"
Nice
-- ThisIsAmirV, 2021-09-23

### ****- "Good App. Solid Devs."
I have never written a review before, but I think this app has potential to really be great.

Right now, it is just *good* but the cross device synchronization and aesthetics of the app are great.

Emailed the developer a feature request and they responded within 24 hours saying they will add it to the next release!

Once this app lets you add custom labels, and re-arrange the order, it will be 5 stars for sure.
