I use this to calculate the percentage change in bitcoin and altcoin trading that I'm going after. This app makes it very easy to pick my price targets. Doing the calculations on a calculator is tedious and doing it this way is much easier considering you can do percentage up and down calculations of numbers less than 1 with many decimal places very quickly.
Good UI, however, the developer should probably evaluate some of the formulas used. Some options don't seem to be giving correct calculations. Whenever I use apps like this I like to cross check them a few time with my own manual calculations. Most people probably just got the app because they don't know how to do that but just look up the formula for arithmetic operation you're trying to do. This cause be a big issue if this app is a dependency for you!
Great calcs but can't get out of app Once you open the app you can't close it - ads cover your phone controls on the bottom on Nexus 5/android. Had to click on ads to get out, but only if ad opened another window, otherwise have to restart phone to get out.
Loved it. I work everyday with percentages and finally found an app that does it the way I need. It would be an easy 5 star if the viduals were better, but it isn't that important. An app like this needs to be useful, not pretty and colorful. If it does is a plus, but I don't mind. Nice work!
Missed the mark on this one The basic app works fine, and does lots of nice % calculations. BUT it appears to be a direct ios port without any consideration for Android Material Design. Personally the pastel colors and all rounded corners found in ios app design makes me want to puke. Also the fact that it auto hides the navigation bar is incredibly annoying and is no reason for full immersive mode for an app like this. EDIT: after talking with developer added a star, but the app could be better as described above.
OMG this app is the shiz-nit !!!!!!! The 'price / quantity' calculator is hands down my favorite toy. I see people griping about the design, well I LOVE it. I personally hate Google material design. But it looks like it's there anyway. But they're implantation is really good, there are some really bad ones out there. I love being able to change the theme. Something material seems to get rid of, a persons choice. The one thing I would add is more themes. To give someone more choices. I'm buying the pro version. It's definitely worth it.
* upgraded underlying libraries
* some small performance improvements
* a bug fix - you can enter expressions with two dots ("2.5 + 3.4")
* new currencies - Maldivian rufiyaa and Tanzanian Shilling
* a mystrious version that hasn't been released to the public. It was just too awesome.
* number formatting may be changed in preferences
Excellent scientific calculator with expressions, fractions, repeating decimals.
