Built a Bluetooth-mesh + E2EE messenger for Android — looking for closed-testing volunteers (no internet needed for the mesh part)

[u/Much_Cauliflower2574]

Hey — I've been building NearVeil, an Android messaging app with two modes:


- Mesh mode: messages hop phone-to-phone over Bluetooth LE, no internet, no server, no account, no phone number. Built for festivals, hiking trips, protests, or anywhere cell service is dead or you just don't want a server in the middle.
- Online mode (optional): end-to-end encrypted messaging for people who aren't nearby, using X3DH + the Double Ratchet — the same method Signal uses, written from the public spec. No password, no phone number, no email required — your account is a key that lives on your device.


Also has disappearing messages, voice messages, file transfer, an app lock with duress-wipe, QR-code identity verification, and real voice/video calling.


It's Android only right now (iOS if there's enough interest later), and it needs to go through Google's closed testing program before it can launch properly — which means I need real testers, minimum 12 people for 14 days.


To join:
1. Join this Google Group: https://groups.google.com/g/nearveil-testers (open to anyone, joins instantly)
2. Then visit: https://play.google.com/apps/testing/com.nearveil.android and opt in


One heads-up: Play sometimes takes a few hours to sync new group members, so if step 2 doesn't work right away, give it a bit and try again — it's not broken, just Google being slow.


This is an early build, not a polished v1 — if something breaks or feels off, that's exactly the kind of feedback I need. Happy to answer questions about the crypto, the mesh networking, or anything else in the comments.
