No more updates but no export feature!

The latest version of this app tells us that there will be no more updates, but you can’t export your data only ‘migrate it’ to another one of HENNGE’s proprietary apps.

Ok at best

It’s ok. I got it for the watch app but moved to Authy. Authy has a watch app and it’s better than this.

Adequate?

Works ok, but I got it for the watch integration which kinda sorta almost works if you hold it right.

If you change the configuration, you have to reinstall the watch app to see the updates. Sometimes it works and it's magical when it does... but I wish it was less magical and more consistent.

new version crashes instantly

Made the mistake of updating without a backup. App now crashes instantly on launch, every time.

Slick design, Solid App

Does just what it needs to, and has a Watch extension to boot! Thanks! My only request would be that the Watch component include a Complication for quick from-the-watch-face access.
