Hello, I am a student at a university and I recently launched my first android app. It is a Calculator. It is free, fast, simple and adfree. It has History implementation as also many themes to change and many display format for different decimal and thousands seperator.
Also, it is lag-free and it uses only a small amount of ram ( <20mb mostly) whereas many "popular" same apps on play store use 80+ mb.
Last but not least, many languages are supported for now, such as English, French, Spanish, Italian, Serbian, Croatian and Greek and German will be added too and many more.
I would love if you could review it, thanks in advance!
