One of only a few scientific calculators I could find that do not require extra permissions (ChampCalc, RealCalc, CalcTastic), and the only one being actively updated. I bought the Pro version to support it. A large font theme would be helpful in difficult light; the Shift labels in particular are a bit small. RealCalc is easier to use in this circumstance.

What an excellent programme. All the interface is well thought out, and mostly intuitive, which is a massive thing with such a full featured calculator. Pro version is just that bit more and more valuable to the developer.

Memory input, store and return function needs to be easier to understand and fluidic to use, I do have tremendous trouble accessing those and hence shifted to the real-life hardware. Earlier :- Support this project and kudos to the developer/s for this excellent as well as feature rich tool

This calculator AND developer is awesome!! It is actively maintained, as well as beautiful + feature-rich. It feels good to support such a great developer with the very modest price of this app... well worth it! Dev: Thank you for this excellent app and all your effort, it clearly shows! Also, the app's minimum permissions is noticed & saluted! With few exceptions, apps that require too many permissions are not on my phone. 🙏🏻 & stay safe / stay well!!

Calculators are utilitarian stuff. You pull it out to quickly calculate your bills and mortgage repayments etc. So clarity and ease of use overrides all other features. So having semi transparent grey font for numbers against a greyish green background is simply mind-numblingly silly. Just use black font and job done. No other complaints.

Has everything I need. Attractive and intelligent layout. Easily configurable.

Pretty cool, it going in a great direction. I'd love to see an easy way to work with SI prefixes (e.g. 10k * 50m + 2)

Bought the pro version purely because i wanted to support the developer. The free version is already more than I needed. 😁
