We'd love to hear from you
We're always looking to improve Skill Builder. Please reach out if you have:
Found something not working correctly? Let us know which app, browser, and what went wrong.
Have an idea for a new training app or improvement to an existing one? We'd love to hear it.
Tell us what you like, what you don't, or how Skill Builder has helped you improve.
Yes! All our training apps are completely free to use with no sign-up required.
Your progress is saved locally in your browser. It stays on your device and isn't uploaded anywhere.
Most apps work on mobile browsers, though some (like typing practice) work best with a physical keyboard.
