Apps for tape!
A tapp is an app that runs on tape!, loaded from the SD card. Each one is a utility (a game or tool — found under setup → utils), a source the tapedecks can record (found in the input source picker: hold PLAY on the first main-menu cell), or a standalone app that replaces the tape engine (hold PLAY on setup).
To install one: download the .tapp, connect tape! to your computer in disk mode, and drop the file
into the apps folder. tape! lists it where its role says — see Starting an app in the manual.

Make your own
The SDK is a header, a build script and a handful of examples. There is also an API reference, and a browser builder that compiles and runs your app - no toolchain to install, and you can hear it before you own a device.
Submit yours to awesome_tapps: just open issue and fill template form. It gets built from source, checked against the device’s loader, automatically screenshotted and published here.
