1Smart - One for All

1Smart - One for All is the essential companion app for Wear OS users looking to unlock the full potential of their smartwatch. Compatible with Wear OS 4 and earlier, it offers fully customizable digital watch faces with extensive personalization. For Wear OS 5 users, 1Smart operates as a foreground service, restoring advanced functionality and enabling interactive complications that integrate seamlessly with third-party watch faces.

Alongside watch customization, 1Smart provides powerful phone features, including five unique widgets for your home screen, real-time watch telemetry syncing, and weather updates from three providers with dedicated widgets. An exclusive feature, 1Smart Emergency, lets you remotely lock your phone if it is lost or stolen, putting security at your fingertips. Free and continuously developed, 1Smart is more than just a watch face — it's a comprehensive Wear OS companion designed for smart, programmable features and better connectivity between your watch and phone.
