I tried Primal in the browser on PC and didn't like it: Very simple indeed to get started (integrated wallet is cool stuff for beginners), but possibly to simple for all that Nostr has to offer (personalized emoji likes, content warnings, delete option, just to name a few)... Maybe the app on phones is better, but can't say since I haven't tested it.

On PC I use nostrudel.ninja in the browser with the Alby extension to manage my key for signing events. Alby connects my cashu.me wallet via NWC (cashu.me installs as a web-app so that you don't risk loosing your funds if you only use it in the browser and erase your history)

On Android I use Amethyst with Minibits.cash wallet and works great as well. Minibits recently integrated NWC which I haven't tried out yet, but with it, apps on the PC should be able to send zaps via the phone!

On Android I also use Nostrudel even though it's not recommended to enter your nsec key directly into the browser.

I'm trying out running a local version of Nostrudel on my server to access it with my phone & PC via Tor and zapping via Minibits/ NWC on my phone via Tor as well, but haven't quite made it that far yet.

Let us know what works for you ;-)
