When answering a short questionnaire, options can be selected by tapping a number on the keyboard, but when you confirm with that number after that and go to the next question, you cannot confirm it with Enter. Well then, when it comes to whether you can quickly move to the send button by pressing the tab key, you can't move until you press it a few times. Also, the time until the screen transitions to the next question is too long (it takes close to 1s after pressing send). Even though it claims to be “short,” the motivation to answer questionnaires is extremely low due to the time-consuming specifications.
