5 stars: I needed to send a scan of my driver's license and my social security card to a new employer and using my S8+ camera app worked OK, but it looks at least as good as any scanner I've ever used with this app, maybe better. It's simple, intuitive, and only took a few seconds to get some quality captures to send along. No one would know I used a phone.
3 stars: The app gives mixed results. With lower ends phones I was able to get better quality scans as compared to higher end phones. With my Honor 8 the picture was too bright, too noisy and lack of detail. It did much better with Honor 6X and Redmi 3S. Turning off flash and glare removal provided better results. But in that case the default camera app takes even better scans. So overall a great idea and good algorithms but needs more improvements. Would revisit in the future.
3 stars: Very good idea. Unfortunately it's not working as expected for me. Quality is too low, specially considering that I'm taking 4 photos (sort of); way lower than making one normal photo with my Nexus 5X. Also the glare removal leaves artifacts behind. But this is a good app for autocropping, and if that's good by itself.
3 stars: It's a brilliant concept, working around glare by stitching multiple photos. A regular photo taken in ample diffuse lighting still comes out better though since the stitched output is severely downscaled. I might keep this app just to see if updates can make this app actually practical.
4 stars: App ...
