★★★★★ gz1wireless gmail · May 18, 2019
The best calculator app for simple math! Simple and elegant GUI, open source, 100% free, no ads, zero permissions. Awesome!
★☆☆☆☆ Jack Wolf · May 10, 2017
Reviews are fake app is fake calculator wastes storage
★☆☆☆☆ Andrew King · Jun 8, 2014
Got large pop-up ad. I uninstalled this app immediately when I got a very large pop-up ad over the calculator on its second launch. It would have been extremely easy to click on the ad unintentionally, especially as it was unexpected. Of course, I can't be 100% sure it was due to this app, but it was running full-screen at the time. I'm a huge fan of open source software, but I like to stay well clear of pop-ups.

How does one get the second-style layout (preview pics 3 & 4)?? The basic style is simply a copy of the built-in Google calc.
