good calculator, but some of the controls are a bit confusing. you have to put your phone on landscape for the variety of tools to show, and some tools are a but difficult to use, but math and numbers aren't my forté, so I would naturally have a worse time than most with this.

I guess it does the job and looks sleek, but there are so many small annoyances that bundle up. scientific mode *requires* landscape; No, just f* no! looking at the history cancels scientific mode again. opening, always starts in non-scientific mode. Considering basic stuff like power factors are in scientliflic mode this is just absolutely horrible. It's like your screw driver always ended up upside down in your hand and you have to flip your hand to make use of it. Usability is key!

This app would probably receive 5 stars if it didn't regularly clear the current figures on the screen. I use this app to keep a running tally of my pay over the course of a week. The app randomly erases my current tally. I save my data at the end of each day, so that feature is helpful. But every day, when I add my new data, the app randomly erases what I've added. So, I have to go back to my saved data and start again. It's extremely frustrating. Please fix it!
