I do a lot of photography, and have tried a lot of editing apps, from VSCO to after light. A Color Story is by far my favourite. The curves tool is a feature I have not seen on any other app, and the filters are the best!! Many of my friends have started using A Color Story after they tried using their filters, and saw how much better they are than other apps.
