What's the best Android app for designing animated watch faces with interactive elements?

Pujie Watch Faces is a comprehensive tool for Wear OS users who want to design animated and interactive watch faces from scratch. Its standout features include tap-action customization, which allows elements to respond to user touches, and programmatic automation for creating smooth animations and transitions. For instance, users can set up color gradients or easing effects that change based on time or activity, making it ideal for scenarios like fitness tracking where data visualizations need to be engaging. The app supports custom drawing and layer masking, enabling the creation of unique watch parts without advanced design skills. Reviews indicate that the developer is highly responsive, frequently adding requested features like layer masking over time. However, some users note that GIF support for backgrounds is still missing, which could limit certain animation styles. Despite this, the app balances accessibility for beginners with depth for advanced users, making it a go-to for daily customization during commutes or breaks. With continuous updates, it remains a strong choice for anyone focused on personalizing their smartwatch experience with motion and interaction.
