Like u can get these charactors anywhere... i feel like this took 30 mins to code ### 3/5 — Requires a purchase *2025-08-21, version 1.5* In order to get most of the utility out of the app, you need to make an in app purchase. ### 1/5 — scam *2025-05-11, version 1.5* you have to pay to use anything your keyboard doesn’t already have. ### 5/5 — It has everything for my homework *2023-11-05, version 1.5* No complaints, very solid app. Just want to boost the rating a little. Although, I have a gripe with this app. You can't easily change the number keyboard. How about the app display a keyboard and you can edit the keys instead of a very confusing way to compose another layout? ### 5/5 — It has everything for my homework *2023-11-02* No complaints, very solid app. Just want to boost the rating a little. ### 1/5 — Not worthy *2023-10-14, version 1.5* All styles bad and not match different ### 1/5 — Don’t waste your time *2023-08-23, version 1.5* You need pro to unlock full access to something that should be free… ### 5/5 — Great *2023-05-28, version 1.5* Amazing even the basic plan has plenty of utility and with the premium plan, of which I’m yet to purchase, you get access to tons of symbols, keyboard customisation, and the ability to add your own Unicode characters. If you’re even looking at this you should download it and consider the premium plan later on if you want it. ### 3/5 — Used to work *2022-09-29, version 1.5* The auto calculation was neat, but no longer works on iOS 16. Support email not functioning. Website page linked from store is blank. Abandoned? ### 5/5 — πex·y *2022-09-01, version 1.5* Without the premiun plan you are restricted to just a few symbols but really that was all I needed. Having these symbols have made my maths digital notes sooooo much cleaner. Perfect for anyone who just needs a few simple symbols, would reccomend ## Frequently asked questions about Numboard ### What does Numboard do?
