Quick intro for those wondering how it works:

1. It does ask for an email first thing, but it's presented as just an optional backup for your account.

2. Then comes the explanation I was looking for in my other comment.

Your Social Battery - Drag the dial to set how social you're feeling — from drained to fully charged. Your friends see this in real time.

Share Your Invite Link - Tap "Share your link" and send it to friends. When they join via your link you're connected automatically. https: //socialbattery. space/?ref={username}

See Friends' Levels - Once connected, you both appear in each other's friends list with live battery updates.

Then you're plopped on this screen:

Settings lets you select a profile picture, nickname (so you can show your real or gamer name presumably, but since your username is part of the link you share it doesn't do anything for security or privacy), and light or dark mode. ETA: I think the nickname feature should also be on a per-friend level, not global.

I think that should be sufficient to give people an idea what to expect when deciding whether to give it a try.

ETA: I am curious what happens when you don't have the PWA open. Do your friends just perpetually see what you last selected, or is there a timeout where it'll just say "offline" (and what is that timeout)?

I've made several edits/additions to this throughout, so you may want to scan it for those if you've already read this.
