Simple and easy to use. Collages are limited to two photographs, so adding or moving photographs takes just one touch. Of course there is no difficult, time-consuming layout selection. Your photographs are always displayed as thumbnails on the editing screen, so choosing pictures is intuitive and smooth. You can also send your collaged pictures directly to Facebook, Twitter, or LINE. Cropping your images to a square frame and sending them to Instagram is simple, too. We hope you’ll add "LineUpper" to your own photography life.
