🟧⚡ TWENTY ONE Companion v1.7.0 is out! 🎉
🔔🟠 Chat notifications — without Goolag.
v1.7.0 is out — the EINUNDZWANZIG app for Bitcoin meetups, events, courses and places:
💬 Your phone now tells you when there are new messages in your chat rooms. No Goolag Play Services, no second app, no push server that knows who you talk to — your phone asks the relay itself.
🔑 Works with the signer you already use: Amber on the same phone (NIP-55) or a remote bunker (NIP-46). Both sign in the background, without asking you every time.
🔋 Easy on the battery: it only looks while the app is closed, never while you are using it, and backs off on its own when your signer is away.
🤫 Off by default — you decide, in Settings › Chat notifications.
📜 Plus: the chat loads older messages again when you scroll up, and photo uploads now reliably land on blossom.einundzwanzig.space.
Onward — stacking sats and shipping. ⚡🟠
