xFormula - Equation Editor

I really liked this app and thought it was a good buy, and I guess it’s not my fault for not fully looking at each plan but why is it set up that you can only use u dear 10 characters for the $5 plan. For the $9 plan is it just the app and not the keyboard? That’s just wild to me because what math/scientific equation is under 10 characters?

the addition of making a selection to copy or cut introduces a bug. The blue selection bars cannot be adjusted and the app locks up. You can only select one character and you have to close the app to get it working again. This bug was fixed with the latest update. 👍👍👏👏 Thanks.

As a mathematics instructor, I would recommend this application to anyone
