Hey r/ATAK — I've been building **OmniTAK Mobile**, an open-source ATAK-compatible client for iPhone, iPad, and Android. It's been on iOS TestFlight and the App Store for a while; the Android build just landed on Play Store closed testing, so I'm opening up beta slots on Android to get the minimum 12 closed beta testers needed to submit my app for official playstore distribution.
Bring your own TAK Server or OpenTAKServer — TCP, TLS, or mTLS. Native UI on each platform (SwiftUI on iOS, Jetpack Compose on Android) with a shared Rust core handling the CoT protocol layer.
**What's in it:**
- ATAK-style tactical map — satellite / hybrid / standard layers, MapLibre
- Multi-server — connect to several TAK servers at once
- Cert import (.p12 / .pfx), keychain-backed storage, enrollment support
- Real-time CoT messaging — position updates, team tracking
- Drawing tools (circles, lines, polygons), saved locally, synced when online
- Plugin system on both platforms — Swift packages on iOS, Kotlin modules on Android, sandboxed
**Join the beta:**
- Both platforms linked from https://omni.engindearing.soy
- iOS — TestFlight invite on the page
- Android — opt in on the web (one tap), then install from Play Store
- Source: iOS https://github.com/engindearing-projects/OmniTAK-iOS · Android https://github.com/engindearing-projects/OmniTAK-Android
Apache 2.0. No subscriptions, no telemetry, no account required.
**What I want from testers:** push it on real hardware against your real TAK server and tell me what breaks — cert flows, network drops, map performance under load, anything that doesn't match the ATAK behavior you expect. Issues on GitHub or DM me here.
Happy to answer questions in the thread.
