Finn is the best dog, and Cowwy is his world-traveling friend and almost-chew-toy. This app provides stickers of both. You can send them from inside the app, and they're also made available in the sticker pane for Gboard, the default keyboard on many phones!
Once you've installed this app, open it and click the "Download" button for the sticker packs you'd like to use. That's all it takes!
When you send a sticker in-app, you're able to decorate it with text and emojis before sending!
This app also includes an Augmented Reality (AR) mode, letting you place these stickers or 3D models of Finn & Cowwy in the world around you. (Hey, this is a hobby project---features doesn't have to fit in, they just have to sound fun!)
On older versions of Android, you may be asked to grant this app access to your camera, microphone, and device storage when you install it. That's used in the Augmented Reality mode only. More recent Android versions won't request these permissions unless you use AR mode.
