This is one good photo editing apps @wilkinshui. Please have time to check my personal review.

Pros :

• They do have darker user interface which i think is a good blending to your edited photos, you can easily check for some improvements.
• There are some built-in effects that makes it a more presentable photos adding some natural sunlight or any weather effects.
• It has also a gallery section which you can easily compare each photos and you may adjust them according to your preference
• Most of those effects really makes your photo a high quality one.

Cons :

• It does need some high-end smartphones to be able to use the application without any problem.
• Still this application is still unstable for it is still on development progress
• To be able to obtain high quality effects, you should purchase some of it via application
