Good option
I like this app because I am able to post pictures from my phone after I take them with my camera. One downside to this app is that you cant do it often because you need to use "coins". If you run out you have to pay for them. Also you edit your photos through a photo editing app. This app doesnt have the location stickers or edits that snap chat has. Its also pretty oblivious when you post a photo through this app because it doesnt fit nicely in the screen, there are black parts that surround it.
