Ive had this app for 4 years on 5 different devices.

I would recommend this app to anyone, point blank. This app has of-course, gone through UI & UX changes, and they removed some key features over time but the fact still remains, its an extremely useful & powerful engine. Giving people access to systematic knowledge and immediate computable access is important!
