It just works. At first I felt silly spending money for a calculator app when there are so many free ones, but this is just very good. It is powerful, versatile, and the interface is intuitive, with well thought out, sensible defaults. It has become my "go-to" calculator app whenever I need to calculate something and don't feel like opening a spreadsheet. I guess I actually use it 10 or 15 times a day, much to my surprise.
Calculator App My needs for a calcultor are broad. Some computing needs (hex and binary maths esp), a bit of stats, some business functions & critically, a user friendly general purpose calculator. This is the only calculator app I have and not come across a need it does not address. Importantly, it does some things very nicely - dual screens for instance. I paid for the upgrade once, years ago and had several upgrades as they came along.
Hands down: the Store's best calculator ever This is so useful with its auto-calculating, dedicated answer bar that constantly updates with real-time input. I bought because the free version has NO internet permissions. I NEVER buy apps (this is my second Store purchase in 5 years) so this speaks volumes. I highly respect the creator's choice to go ad-less in its free version, in an era that intrudes on users' privacy left and right. Thanks, IP!
Best Scientific Calculator App I've messed around with quite a few scientific calculator apps for Android and this is the best. It seems to have great functionality and the full feature set of a sci-calculator. What I particularly like about it compared to other apps is it doesn't try to needlessly mimic the layout of a physical calculator, pretending it's something it's not, and instead makes good use of space, placement of buttons, and is simple but elegant looking. And it has some neat features other calc apps don't have. Worth it.
Very good Perfect in terms of functionality and design, far better than stock one. Easy to use. Appreciated the free version for absence of any advertisement at all or other annoying things. Thus, bought the pro version just to support this vise developer. Definitely a must-have calc!
Good but add Material Design It is the only calculator that works like I want it to but it doesn't match Google's new Material Design which has taken over the rest of my phone.
