It's very early. It's only the first release of a live test version (0.2.0) so there be dragons, but it's surprisingly stable. Though don't sent more than you're okay with losing and periodically transfer out to another wallet.

garnet is forked from an Amethyst version just before Vitor went with the gossip model and there are little bugs that Amethyst already fixed. The biggest bug I've found over the past couple days of testing is trying to edit a draft deletes the draft.

Also, it does not install if amethyst is already installed due to conflicting signature but same app details. However, some have used apk editor to install both alongside each other.

Personally, I nuked Amethyst because I accept the risk of this alpha/beta release and know I going to daily drive it so I can help the dev with fb.

If you're good with the above, give it a spin. It's awesome!
