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.

Waste of money

Can't import QR codes exported from google authenticator app. Only gives option to type secrets manually, cant import mass accounts at once - don't bother using this if you need to transfer from another device

Developer Response ,

Hello, Roasty_Mako. Sorry to hear the app is not working as your expected. Currently, auth. doesn't support transfer from another app. But your suggestion will be considered in the future roadmap of the app. Thanks for your understanding.
