Here are a bunch of ways you can use an app to make a picture that much better
1. VSCO
The most obvious one of course. If you're not on VSCO, then what are you doing. VSCO has a huge collection of filters and editing tools to make your pictures pop. The premium membership unlocks more features and personally I think its worth it.
2. Glitche
This app lets you do cool things like 3D effects and eyepopping swirls. If you take a picture on a boring background, this app will help make it better/
3. Unfold
This application gives you access to a variety of frames and polaroid backdrops that will make Instagram stories gorgeous.
4. Adobe Sketch

5. PicsArt
