Install Blink. Verify everything.
No app-store account required. The build is signed with our own key and hashed — compare the SHA-256 below before you trust it.
Already on v1.2.x? Just install over it — same identity, no re-pair needed. v1.4.0 adds end-to-end encrypted group chats (same encryption as your 1:1 chats). Want to use groups? Everyone in the group must be on v1.4.0+ — the group message format is new, so friends on older versions can't join a group. Send them this page. Coming from v1.1.x or older? New identity format — after updating, re-add your contacts via QR.

Don't trust us. Reproduce us.
Blink is open-source — the full source is public on GitHub under AGPL-3.0. Every build ships with a SHA-256 you can verify against the file you downloaded. Next: reproducible builds, so you can rebuild the exact APK yourself and confirm the hash byte-for-byte. We'd rather you check than take our word.
- SHA-256 published for every build
- Public source repository
- Reproducible, deterministic builds — soon

Leave a star rating and a note. Honest reviews only — we don't moderate for vibes.
Fund the work, not the surveillance.
Blink takes no money from ads, trackers, or investors who want your data. It runs on people who believe private communication is infrastructure. Donations are optional and never required to use anything.
Monero only — no card processor, no Sponsors page. Those would tie every donor to a legal name, which is the exact thing this app exists to avoid. We'd rather take less money than keep a list.
Tap to open in a wallet, or copy it by hand. Donations are anonymous to us too — we can't thank you personally, and that's the point.
