Mental calculation

Great app, but why do you need access to the user name and pictures? This app rises major confidentiality concerns.

Very good Thank you

worst app

хорошее приложение, но я прошел все примеры за два дня, хотелось бы больше уровней. Жду обновленний

useful app.

Good

A really good app, I use it daily. In each level, you have 60 seconds to perform 10 calculations. I appreciate the fact that you have to type your answer and select the good answer among given possibilities. Things that could be improved in my opinion: 1. When the player doesn't have time to finish the 10 calculations, give him the result of the last calculation he was doing (even if he didn't submit a number). 2. I don't like the fact that you can pass a level with 3 wrong answers. You'd rather type "000" than to spend time to calculate something like 23*47. I think the conditions to pass a level should be 10 correct answers, and not at least 7 good answers out of 10 questions. 3. In the same idea, I don't think you should stop the player when the chrono reaches 60 seconds, but rather let him know that he failed but let him finish if he wants to. I'd rather know that I finished a level in 63 seconds (and thus failed) than seeing the results tab showing up with an incomplete list.

I like the 😎😎

I like 👍 this app

I like how you suggest skipping five levels if it is too easy.
