Hello! The errors I spotted are not that significant, but I will cite a few examples:

Naturally, our mobile devices, emit blue light.

No need to add a second comma there. This sentence should read: "Naturally, our mobile devices emit blue light."

This review would be a little different than others I've published.

This sentence should read: "This review will be a little different than others I've published."

So my review would be a way to explain how the app works.

Let me rephrase that: "So my review will be an attempt to explain how the app works."

I hope you will find this comment useful.

Have a good day!
