Photo Frame is an application for Android that gives you access to the set of tools for editing various images.
The app is completely free and does not require you to create a personal profile. However, there are a lot of advertisements that can distract you from the process sometimes.
You have the ability to unite photos that you have on your phone into a collage. It is possible to adjust the size of it, and the position of items.
There is the opportunity to edit the outcome, by changing various parameters of the picture. It is possible to alter the brightness, contrast, blur and many more. You can also crop the image, change its resolution and use all other basic tools.
Photo Frame has everything that you may need for quick editing. But if you want to do it in the more professional way, it is better to use apps like Adobe Photoshop Lightroom.
Moreover, in this app, you can find the collection of beautiful frames. You can apply them to any picture and save the outcome to the internal memory of your phone.
