I love that this app actually works. I have to use it for work to create specific orders and calculate on percentages, adding and multiplying to get a transaction done. This app save me a lot of trouble when filling out paperwork. This app is speedy, easy to use and perfect when you need a quick answer. I like the fact it's really simple, as I find it confusing working things out on a calculator! Thank you, really appreciate the effort and time put into making this app.

This is one of the best calculators I've downloaded. I study computer science, and I have often to solve math problems, this app helps me a lot. Five stars, I've got nothing else to write about. It's simply great!

Works like a proper scientific calculator. I've used three other scientific calculator apps, and this one by far is the best. 1. Good User Interface 2. Smooth Performance 3. Accurate Results 4. Easy to use 5. Always perform as designed.

Acts like a real scientific calculator, and does it perfectly. Easy to use. Support copy, paste,.. I would have a suggestion for a little change. You should allow send results through email.

Looks good like how it adapts to side bar usage. Thing that makes it not usable is it brings up the keyboard on my surface all the time which blocks the calculator keys. If the creator found a way to prevent that I would give 5 stars. As is now I can't use it
