Useful Good idea, genuinely helps train eyes to pick things up without getting stuck and staring. One feature request - please add a setting for the time between the image and giving the answer. Should allow you to have a few seconds to close eyes, relax and visualize what you have seen, even when image is fast moving. Also pay version with no ads please. Ads make game difficult! That would be a five star app!
An Ad free paid version will turn in into 5 stars As others asked for. Ads disturb concentration.
OK... No sense of downloading it
