SciKey - Scientific Keyboard

This is a really useful keyboard, but it feels like it's incomplete. I mean, when you are writing a math formula, you need to use, apart from the integer and the sqrt symbol (which are phenomenal) you also need to use all the math symbols (+ - x * ...) and it's quite unproductive to have to change the keyboard for that. Also it would be useful to have the "normal keyboard" there, just to write constants like a, b, c or the radius is a sphere, with the letter r, R... Your keyboard is great, but at the moment is unproductive and not useful at all. Having to change the keyboard to write a normal letter is not cool. Keep on the good work, add all these features and I'll recommend this to all my engineers classmates!

I always has trouble with unicode keyboards either missing symbols I need or having to look really hard. This app makes it a lot easier with a fully customizable keyboard. One suggestion is to have more modes or adding key held options (like holding "4" to see "4","⁴","₄")

it has all the symbols i've been wanting to use for free (most notably √x), has a very low paywall of less than a dollar and has an excessive amount of customization options that allows it to be literally a keyboard of your most used keys rather than one solely for math, one with 84 keys instead of the standard 80 with some rather useless ones like €

It’s all good… but why is there no ρ symbol?

It’s an okay app. Would be nice if I didn’t have to switch between keyboards to type other letters.

Not good to use

I needed something to help me type out complicated chemistry notation, and I’d highly recommend getting the pro version because I’ve been able to customize it to my exact needs. For the amount of characters available and the amount of space allowed on the keyboard, $0.99 is incredibly worthwhile.

I purchased the upgrade and the customized keyboard didn’t upload. The link for restoring pro isn’t a link at all. I want my money back or this needs to be fixed ASAP.

Very little utility without handing over a $, which would be ok BUT YOU have to create the keyboard with new characters instead of them just being made available via slide to additional keyboards AND you must give them FULL ACCESS.! I think NOT! This is my first ever review so they really needed to do the function badly.

I needed a math keyboard for writing proofs. Unfortunately it is very inconsistent; There are 3 panels to choose from. Among them, one panel has an entire row dedicated to ordinary variables such as a b x y z etc. Why? The issue is that instead of wasting space with these letters (as iPhones already have letters like this) why not add more symbols? This keyboard includes the conjunction symbol, but not disjunction? Quantifiers? Implication? set notation? These symbols could’ve easily been added instead of letters like a b d i j ... Instead we see clear poor design choices. This is the best math keyboard and that says a lot. Unfortunately it isn’t practical. For lower level math this is sufficient; for higher level, don’t waste your time.
