# Free tools

Small things we made while building Desktamer, free to use. They run in your browser: nothing you give them is uploaded, and there's nothing to sign up for.

- [Codex pet checker](https://desktamer.com/tools/codex-pet-checker/)

  Drop in a Codex pet to watch every row play, check it the way Desktamer imports pets, fix rows that run backwards, and save a GIF. It takes a .codex-pet.zip, a pet folder, a pet.json with its spritesheet, or the sheet alone. It's Desktamer's own importer, rewritten for the browser and tested against the app's, so if it says Desktamer will take a pet, Desktamer will.

- [Focus timer with a pet](https://desktamer.com/tools/focus-timer/)

  Work in 25-minute rounds with a 5-minute break between. Luck and Pati nap while you focus and cheer when the break comes. Every fourth break is a longer one, of 15 minutes. Set your own lengths, such as 50 and 10 for deep work, press Space to start or pause, and see how many rounds you've done today.
