Not sure what the purpose is
This app appears to offer things like panorama and grid photo creation, but it actually splits one single photo into a grid of separately saved photos in your photo album and makes a single picture into a series of panoramic shots which are then saved as separate photos. The watermark feature doesn’t work. It’s not a watermark really. It just pastes your chosen picture onto the photo at pretty much full opacity. I’m not sure what the purpose of this app is. I will change my review if the developer can explain, but there’s no tutorial that I can see.
