Everyone types on a phone differently: speed, pauses, where thumbs land, how mistakes get fixed. This test records how you type, so it can be replayed and studied.
How it works
You'll write 2 short texts (up to 200 characters) for the same prompt.
Text 1: hold your phone however is comfortable. Text 2: use only the thumb of your non-dominant hand.
Type as you normally would, typos and all, then tap Send. There's no autocorrect.
At the end, tap Share recording to send it to the researcher.
Only your texts and taps are recorded, with no personal or device information. Don't write anything private.
