Support email not functioning. Website page linked from store is blank. Abandoned? ### 1/5 — Too many fees(scam) *2020-11-09, version 1.5* I think there are way too many thing that need to be paid for, for example you have to pay a dollar just to change the color of the keyboard, and if you think about it if the developer keeps getting people to pay one dollar guess how much money they’ll have😡 ### 1/5 — Unclear on usage... *2020-09-17, version 1.5* Not sure if I’d buy this without seeing better samples of what it could do. Does this allow formulas? Not clear! ### 3/5 — Close but no cigar *2020-09-15, version 1.5* Well you only get a few symbols like × ÷ π¹²³⁴⁵⁶⁷⁸⁹⁰ and that’s it I don’t wanna waste my money but I like the idea ### 1/5 — Don’t Purchase *2020-07-05, version 1.5* This app had a few keys and when I purchased the .99 full version it didn’t have much more than the basic version. Check the privacy waiver it wants you to approve. Not worth the dollar I wasted. I immediately uninstalled. ### 1/5 — Needs to pay *2020-05-02, version 1.5* You need to pay to unlock the full version of the keyboard. This doesn’t even include basic symbols such as the square root function. Don’t download, it’s a waste of time ### 1/5 — Rubbish *2020-04-21, version 1.5* Don’t get this app it is a wast of time and apple’s original keyboard has more ‘math’ buttons that this app.😡😡 Just stick to the originals.🙃 ### 2/5 — Great app *2020-04-16, version 1.5* It’s a great app but the keyboard layout should not be pro because some people may need or be used to the other layouts. Thanks!!! Helps with communication with algebra teacher!!! ### 1/5 — waste of time *2020-01-16, version 1.5* pointless app, you have to pay to use most of the symbols so it’s not even worth the demo version. ### 1/5 — DESCRIPTION IS DECEPTIVELY SEDUCTIVE *2019-11-20, version 1.2.1* You’ll need the Pro version to access symbols which are not found on the standard keyboard. Otherwise, it’s good for nothing. ## Most critical reviews (10 lowest-rated) ### 1/5 — Money *2026-02-14, version 1.5* Idk why it cost money when its literally just typing unicode charactors. Like u can get these charactors anywhere... i feel like this took 30 mins to code ### 1/5 — scam *2025-05-11, version 1.5* you have to pay to use anything your keyboard doesn’t already have. ### 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… ### 1/5 — Very bad app *2022-03-22, version 1.5* All are pro ### 1/5 — Don’t waste your time *2022-01-13, version 1.5* You can’t use any math symbols or any symbol that isn’t already on your phone without the pro membership. Waste of time if you don’t use pro ### 1/5 — Backslash limited to pro mode *2021-10-13, version 1.5* Title says enough, this thing is a money grab. They could have at least only put the fancy math symbols behind pro mode, but no, they made it unusable instead. ### 1/5 — Pay to use keys? That is ridiculous *2021-09-16, version 1.5* I have to report it. The app store has policies against dumb apps to farm purchases, how did this get approved?? ### 1/5 — 1 estrela porque não pode dar 0 *2021-06-22, version 1.5* Péssimo… coloca o app como gratuito mas só libera exponencial e o pi (este último possível de acessar apenas incluindo o teclado grego já nativo do iOS). Já que perdi meu tempo testando, aproveito logo e deixo essa review tentando alertar os desavisados: também não perca o seu. ### 1/5 — Preço desnecessário *2021-03-08, version 1.5* Cara, por que eu pagaria 5,00 reais em uns símbolos que eu usaria de vez em quando? Sinceramente, as únicas coisas que adicionam no teclado de graça são o expoente e o número pi ## Most praised reviews (10 highest-rated) ### 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. ### 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. ### 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 ### 5/5 — Very helpful keyboard, no issues *2022-07-16, version 1.5* So what, it costs $0.99. Thats a fair price for the convenience this keyboard app brings. Love having the great math symbols at my fingertips. For the keyboard to work in all apps, I did have to reboot my iPad after adding the keyboard. Other than that, no issues. My only suggestion would be to include superscripts and subscripts for letters as well. ### 5/5 — 1 + 1 = AMAZING *2017-08-21, version 1.1* 'Tis is a very good app I have been using it during for a few hours and it is very good. Especially the auto complete ### 4/5 — Good but buggy *2021-07-29, version 1.5* This app need to be updated. ### 4/5 — Some things need to be added *2020-09-12, version 1.5* I like the keyboard so far. I got the pro version which I am happy about but I wish there were a way to make super scripts and subscripts with things other than just the numbers. ### 4/5 — Great, but... *2020-07-22, version 1.5* This is a great app! You can do so much more with this keyboard. Two complaints I have, though, starting with the first one, is the fact that the app doesn’t have superscript or subscript variables (such as x, y or z), which is a big downside for wanting to write out an exponential or logarithmic equation/function; they only have superscript and subscript for numbers and a few mathematical signs. Another complaint is that you can’t write a fraction with the fraction bar being horizontal like you would writing a fraction on paper. For example, you have to write fractions like this: 1/2, which is fine, but I would like to see a horizontal fraction bar added into the app. Other than those two things, everything else works fine, and this is a great app! ### 4/5 — Algebra *2020-01-26, version 1.5* I want to solve algebra :/ --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
