CamScanner is a very useful app. Instead walking into the market and getting paid for scanning docunents, pictures etc I can now do all the scanning right from the comfort of my bed for absolutely free. Scanning quality is way better than the normal picture we used to take from our phone. Quality is just like original scanner we get paid for. Its very handy its just like I am walking with a scanner in my pocket. This is a must have application. I loved it. Everyone should install this.
