Very good but…

To the developer – thank you for your response and your hard work on the app. The update with the shorter time makes it spot on terrific. Five stars to you!

My kids like playing this game but the time is too long. They want to shorten it to two or three seconds. This would be a simple add into the settings. Please add this feature. The time on the multiplication one is too short. Please make adjustable for kids of all ages.

Having said that this is a terrific app. With that one feature I think I would give it a four or a five star. Keep up the good work.

The latest release of Newton now allows this! After playing a few games, you'll be able to chose the time mode that you want, which includes 2, 3, 5, and 10 second games. I hope you try out the new update! 😇

Can’t adjust the time

Can’t seem to adjust the time as is featured in the screenshot in the AppStore. I’m using iPhone X, iOS 11.2.

A second the other reviewers request for a more adjustable timer (though would settle for at least the options advertised).

Developer Response ,

Sorry for the misunderstanding! You actually can adjust the time as featured in the screenshot. However this is only accessible once you've played a few games, as features in the game are progressively 'unlocked' the more you play. You can change the time of the game by going to the Settings 'cog' once it is shown on the home screen of the game.
This is intended to help players get straight into the game as fast as possible. I hope that helps!
