Your Worst Characters

The 5 characters missed most often this session.

Practice a few characters to populate this list.

Car Mode

Listen only — nothing to type. Each character plays five times, with two seconds after each play to say it out loud, then the next one. Keeps playing if the screen turns off. Uses this page’s tone and volume.

Car Mode for a walk or hike. Each character plays five times, with two seconds after each play to say it; after the fifth, a voice says the character so you know if you got it. It keeps playing with the screen off and the phone in your pocket. Earbuds recommended.
