Lottery-Style Mining: Mobile devices produce very low hashrates. Do not expect meaningful profit — treat it as lottery-style mining. OverMobile is built for the Rusty Kaspa Stratum Bridge and will only produce valid shares on pools that support low difficulty and the Rust bridge protocol. The OverBuild Labs Solo Mining Pool is fully compatible.
Distribution Note: OverMobile is distributed via direct APK, F-Droid, and Obtainium. The Google Play Store prohibits on-device cryptocurrency mining, so OverMobile will never be available there.

Features

True Mobile Mining

Native kHeavyHash miner ported from KASDeck ESP32, compiled for arm64-v8a, armeabi-v7a, and x86_64. Real mining, not simulated.

Thermal Aware

Automatic throttling pauses mining at critical temperatures. Monitors CPU temp, battery level, and thermal state in real time.

OverManager Ready

Pair with OverManager using a 6-digit code for remote telemetry and command execution from your desktop.

    Set a worker name.

    Use a short label like phone1 — no spaces or special characters.

  4. 4

    Set the thread count.

    Start with half your CPU cores. Increase for more hashrate, decrease if the device runs too hot.

  5. 5

    Tap Save at the bottom of the Settings screen.

  6. 6

    Go back to the Dashboard.

  7. 7

    Tap Start Mining.

    The dashboard will show your hashrate, temperature, battery, and share count.

Optional: pair with OverManager for remote monitoring and control from your desktop — see the OverManager Integration section below for the step-by-step and screenshot.
