3 years ago from , Full-Stack Developer

I always forget the formula for calculating percentage, will do an Open Source, OS X Menu Bar app for this reason. I know a site that does exactly the same thing Percentage Calculator this is for the topics. In menubar app (what is menubar app?) there will be 4 options like this guy did. But I want to create a user-friendly, simple experience for people. Does anyone want to collaborate with me on this tiny project?
