Web timer vs desktop app: when to use which

  • Use a web timer on Chromebooks, library/school computers, or locked-down work laptops where you can’t install software.
  • Use a desktop app on your own computer: it works offline, floats always-on-top of your work, and won’t get buried among browser tabs. Pomotroid is free and open-source.

Most focused people end up with both: Pomotroid on the main machine, Pomofocus bookmarked for everywhere else.
