I use Pass on both the desktop and Android and have done for a few years now. It works really, really well. I couldn't imagine using anything else at this point.

The only "issue" I've had is formatting my phone, but forgetting to first back up the GPG key I used. The solution is just to create a new key and (from my desktop) reencrypt all the passes. It's not hard, but it does take about 10 minutes.
