Postr 1.1.1 lets you speak a note without leaving the composer: tap the microphone, then choose Cancel, Paste, or Post from the same bottom action area. Mention search follows the caret through the middle of a draft, and a selected profile gains distinct styling so you can see which `@name` will become a real Nostr reference before Amber signs anything.

Introducing Postr, a deliberately small Nostr composer for Android.
Post. That's all.
A durable outbox survives airplane mode, process death, and unreliable relays. Once Amber signs a note, Postr keeps working until it can verify that exact event on your relays.
Private keys stay in Amber. Postr requests only two signing capabilities: kind-1 notes and file-scoped Blossom upload authorizations. It cannot read DMs, sign unrelated event kinds, or publish a relay list.
Postr also includes verified Blossom attachments, mention search, opt-in link previews, and a zero-blue night theme you can retint end to end.
