Ratings and reviews

Finally, no more using the annoying default Google Calculator which has tons of Google data collection draining my battery sending my data back to Google servers. This calculator is very lightweight at only 2MB and it has a lot of options in the settings. I love the AMOLED dark theme which helps save battery. My only suggestion would to add a "floating window" option like on LG's old apps (known as QSlide).

One staring, just so you notice this review. Indeed your app is a 5 star one. I'll update later. Can you please add tile so it can be access from notification menu ? Edit: Thank you for this update.

Whoa! An calculator without spying and constantly updated privacy terms! 😆 And it can calculate too! I hope it also is without constant updates and updated privacy violations too as math is quite stable. Think about the density of the dystopia we are living in, you dont natively have a unspying calculator (or keyboard or etc..) on your superphone and at the same time such option is made hard to find with dark patterns on app store.
