Ratings and reviews

A satisfactory app, it let me write the equations needed. But it lost stars because I couldn't find any settings to enable haptic feedback which is a big downside. I also couldn't find a way to change the size of the keyboard. On an pixel XL it is half the size of the Google keyboard, this made it much harder to adjust to. I had to consciously aim my thumb for each key, instead of using muscle memory.

Minus three stars for not being able to swap keyboards without having to close everything and go into settings to switch back to Gboard. I can switch to it from other keyboards but it doesn't have the functionality to do the same. This makes it horribly inconvenient to use as this keyboard is not great for conversation. Would be 5 stars if it wasn't such a pain to switch. No updates in three years means it'll probably never happen though.

This keyboard REALLY helps...so much better than trying to construct symbols from scratch using graphics/icons etc. What's really cool as well is that you are not inundated with eleventy-leven ads when using it👍. One request (not a criticism), some symbols still need to be added such as diameter, parallel, arc etc. Then again they may be there and I'm just being blind.
