User Reviews

Users praise Numboard for its math symbol library and potential, but major drawbacks are heavy paywall gating, perceived poor value for money, missing advanced notation, limited customization, and occasional reliability issues. Improvements in pricing, feature parity, and bug fixes would broaden its appeal.

Pros

Wide set of math symbols and notation accessible from the keyboard
Pro version unlocks extra features and is valued by users who upgrade
Helpful for math education and algebra communication

Cons

Pro paywall: most symbols and features require the Pro version; free version is very limited
Concerns about value for money and price being high for what is offered
Missing advanced notation (superscripts/subscripts for letters, horizontal fraction bars)
Limited keyboard customization and some styling issues
Bugs and reliability concerns (decimal precision errors and cross-app issues requiring reboot)
