Scarlet

Now with support for iOS 26 and Liquid Glass!

Let's face it, there are a lot of developers who like the idea of an issue tracker, but find it too much effort to use & maintain for solo, indie or hobby projects.

Enter Scarlet. Scarlet is a personal issue tracker that saves to a file that you can include in your project directory, or anywhere you prefer. No accounts, no cloud services, no syncing, no third-party integration. Just a simple place to file away your project's to-dos and close them when they're complete.

Add tags to an issue to help organize things, and that's it — it really couldn't be simpler.
