Simplenote uses Simperium to store and sync notes across multiple app platforms. The Simperium libraries handle all the networking so developers can focus on building a great user experience.

Third Party Applications

We are not supporting additional third-party Simplenote applications at this time. This could change though, so please stay tuned!

Some older applications may still be using the legacy Simplenote API at https://simple-note.appspot.com. Note that this API has been deprecated and will no longer function after October 1, 2018.
