If you want to edit photos on your mobile phone,then you've came to the right place,I'll tell you what options you have:
*A professional paid app. *A professional apps that has sooo many ads. *And then you have the best tool for free !!.
This tool I'm talking about is free for a reason,it's made by Google which collects profits in a different way,that's why this app has many tools and filters that are so helpful and could be life saving if you create content usually or shoot photos with your mobile all the time.
It's like a mini photoshop on your mobile in which you could do the color correction,healing,sharpness,Brush,Structure and so many other features.
So if that what you came for,why are you still here?
