Update: Three or four years later, this is still my favorite calculator (in fact, I uninstalled the others because I never used them), and well worth whatever the Pro version cost. The devs keep it updated, and 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.
Most Excellent! A clean uncluttered attractive well-crafted interface. I use this as my everyday basic calculator. Scary math functions are available if one is into that kind of thing -- they are on another page, discretely waiting to be called for duty. I gladly paid for the PRO version years ago. The developer or some successor of his has been making improvements. Many developers quit after few years. I have this on my half-dead Nexus 4 and BlackBerry Passport [Thanks, Cobalt, for your divine labours!].
What I especially like is the simple yet flexible interface. You are able to change the priority in which calculations are evaluated. It does just about anything anybody would want from a non-financial calculator. It's easy to learn, and I have never EVER found it to have any problems.
Change nav bar color to dark in dark theme for s8.
Best and easiest to use calculator I found yet!
