Bring the World’s Largest Watch Face Catalog to Your RTOS Smartwatch

Custom watch faces are one of the most loved features in premium smartwatches. But for manufacturers building on RTOS or bare-metal systems, that kind of user personalization has been hard to reach until now. With LVGL’s lightweight UI engine and tooling, and Facer’s 500,000+ face catalog, OEMs can deliver a premium, customizable watch-face experience on resource-constrained devices without building a full platform from scratch.

Together with Facer, we provide a complete solution:

• LVGL Runtime + Watchface Loader: Lightweight graphics and data binding engine for RTOS devices
• Facer Converter Tools: Convert Facer watchfaces to LVGL-compatible assets
• Distribution & Sync Support: Load faces via mobile or OEM-specific channels
• Flexible Licensing Options: Commercial runtime available via LVGL Pro licensing tiers

This integration is part of LVGL Pro. Commercial licensing enables:

• Runtime deployment on customer devices (RTOS / bare metal)
• Custom integration and branding support
• Volume-based pricing with per-device royalty models

We're already speaking with launch partners and wearable brands interested in adopting the full stack. If you'd like to explore integration: Reach us at lvgl@lvgl.io
