New update sucks

The new update is a massive downgrade.

Everything is too small, making it harder to play comfortably.

The transition between questions is too long, breaking the flow, and since each round only lasts one minute, those delays significantly reduce the number of problems you can solve.

On top of that, you can no longer choose your keyboard size, making typos more frequent.

Please bring back these features.

nice app with no ads

Wonderful learning game

My daughter has learned to be faster with her multiplication and she loves this app.

Хорошее приложение

Меня порадовало, удобно можно практиковать устный счет практически всего, хотя я скачал по сути только иза таблицы рейтинга, не хватает только соревнований с другими и решения более сложных задач такие как квадратные уравнения и другие

Very user-friendly - just 2 suggestions!

Great app that offers a user-friendly interface to improve mental math skills. The daily goal and trainer make it easy to commit to improving your skills. It is also visually appealing and provides good customization options.

(1) One suggestion is to allow further customization under Trainer > Times tables. It would be great to be able to select within the column which rows to keep. For example, if I only select column 12, it would be nice to be able to unselect, 12x1, 12x2, etc. and focus on the exact equations I’d like to work on.

(2) For the custom trainings, it would be useful to be able to select any numbers over, less than, or between a certain number. For example, if say I wanted to work on addition equations that include the number 9, it would nice to be able to have Number B as greater than or equal to 7 or between 7 and 19.

Overall, great app!
