Pros: * best performance on large amounts of math * extensive library of symbols * intuitive and fast to use Cons: * can't create tables inside of tables * Doesn't adapt properly to the screen size on an LG G7. If you run it in full screen mode, the edit button at the top doesn't display, so you can't open saved files. If you run it in compatibility mode, the bottom buttons are squished into a few pixels, making them unusable.

Overall, this is an excellent app. However, I would greatly appreciate the addition of the Cambria Math font for equations, as it provides a more professional look. Also, some key features are missing, such as customized root symbols (e.g., \sqrt[x]{x}). I kindly request the developer to consider adding these improvements in future updates to enhance functionality and user experience.

Realy this app was very useful and helpful but geometric and physics circuit diagrams have removed. So this app is not so useful as it was. I expect, the problem should be fixed soon.
