A few years ago I noticed that most of the unit converters on the digital stores were ugly, not immediately usable, with ads and tracking software. I thought it would be a good idea to develop Converter NOW in order to solve all these problems!
It is made to be easy, fast and immediately useable: just start typing and immediately you have the real-time conversion with all the other units of measurement. It is customizable: the units can be reorganized according to your priorities and your use case. It integrates a Calculator that let you do the calculations in every page.
Currency conversions are updated daily. Choose your favourite dark or light theme. Full Smartphone, Tablet and Web app support. It is free, no ads, no analytics, no permissions (just Internet to update currency conversions). And first of all it is open source!
