WearOS: Extended Long-Range (ELR) Calculator

Full Ballistics Power, Decoupled from Your Smartphone

The Only Native WearOS ELR Solver

ONESHOT Ballistics for WearOS is not a remote display; it is a full-featured trajectory engine that executes 10,000 Monte Carlo iterations locally on the watch hardware. By utilizing the wrist-worn device's barometric sensors and magnetometer, it provides real-time ELR solutions for Coriolis, Eötvös, and Density Altitude without requiring a smartphone connection.

Hardware-Level Integration

3-Axis

Magnetometer

Calculates firing azimuth for real-time Coriolis horizontal deflection and Eötvös vertical correction.

Baro

Pressure Sensor

Ingests station pressure directly for offline Density Altitude (DA) computation at the shooter's exact position.

BLE

Sensor Feed

Pairs directly with Bluetooth chronographs and wind meters for low-latency telemetry updates on your wrist.

Why Choose WearOS for ELR?

In high-stakes ELR competitions and remote hunts, the smartphone is often a liability due to battery drain, bulk, and environmental fragility. The ONESHOT WearOS engine allows you to:
