★★★★★ Batman · Jan 25, 2021
Simple, no bs, its simple, no ads, no iaps and its OPEN source. Does your calculations. What else you need?
★☆☆☆☆ Alan Squire · May 14, 2020
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.
★☆☆☆☆ 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.

Reviews are fake app is fake calculator wastes storage
