Latest reviews, Japan App Store.
For some reason they decided to change the reaction time test from an instant color change (from red to green) to a gradual fade to green, which results in much less accurate reaction times. (Went from average 230ms to 300-330ms) Weird change to make to an app that otherwise worked well. Will change review once this is fixed.
why pay monthly
i accidentally clicked i didnt like the app in the app, so you can mark one of them down as false, i love you sooo much
Low the simplicity seems like theres more modes now awesome
Pretty good but I don’t like that you have to pay money to get the full experience.
