Keycap Keyring is a custom app that allows you to decorate and press keycap rings that resemble small keyboard merchandise.
Starting with a basic 4x1 layout, you can select switches and keycaps for each slot. Pressing a keycap plays animations, sounds, and vibrations that simulate pressing a real keyboard.
The Photo Keycap feature allows you to register your desired images as keycaps, while the Record Sound feature allows you to apply short sounds you have recorded yourself as switch sounds.
Purchasing the Premium plan removes ads and grants access to premium layouts, keycaps, and photo/recording extensions.
Keycap Keyring operates without a login or server, and photos and recording files are stored in your device's local storage.
