Your Watchface Engine | 1Smart

Your Watchface Engine: widgets, insights, security, weather. You'd be surprised what your watch can do.

I built this app for myself — because I couldn't find one that actually worked the way I wanted. Now I'm sharing it with you, completely free.

1Smart Core: Ultimate Smartwatch & Phone Companion for Wear OS

Unlock the full potential of your Wear OS watch and phone with 1Smart — the free engine that powers advanced watch faces, real-time telemetry, and smart widgets. No subscriptions. Just smart features, your way.

Seamless Integration

• Works with modern Wear OS watches — Samsung Galaxy Watch, Google Pixel Watch, and more.

Battery-Friendly

• Lightweight design keeps your watch running all day without unnecessary drain.

For New Wear OS Smartwatches

Break free from the latest Wear OS restrictions. 1Smart Core runs as a foreground service, restoring advanced functionality:

- Interactive Complications — add large, tap-to-control elements to any compatible watch face
- Ecosystem Sync — pair with 1Smart WFF Watch Face or 1Smart Classic for a unified experience (guided installation inside the app)
- Programmable Features — smart, customizable tools that go far beyond basic XML watch faces

Powerful Phone Features

1Smart Core supercharges your phone too:

★ Dynamic Widgets — customize your home screen with glanceable, interactive widgets for weather, pressure, steps, and more
★ Real-Time Watch Telemetry — sync and monitor heart rate, steps, and battery status directly on your phone
★ Weather Feed — instant updates from three trusted providers. Get forecasts, temperature, and conditions at a glance — on both your phone and watch
★ 1Smart Emergency — a discreet remote phone lock feature. Lost your phone? Lock it instantly from your watch
