The filter is very easy, you can adjust it as per your requirement or need. It's free so not much expensive compared with other software/apps of same nature available in market. I have used this app since long but there are some minor issues like sometimes when we try to click photo from album then that particular image doesn't get selected rather previous one gets highlighted instead (it happens most often). So if anyone wants to save his precious moments than use Filpixel filters otherwise there will be no point saving those pictures because they won't look exactly how he wanted them to appear later while sharing. Saving our memories by using these types of apps makes us feel better about ourselves hence helping people realize what kind of person they were earlier.
