Nice idea. Poor results. I thought this may be a good way to scan old family slides. However, the scanned images are not nearly as sharp as the originals. Also, the light from the white screen shines so brightly on the back of my phone that it reflects onto the the slide being captured--not good. Don't be like me and waste $30 on a one-year subscription. I should have tested the app by subscribing to the monthly plan.
