I wanna give my review as well.
Honestly, I’ve seen a lot of shitty guides and at first I did not trust this one at all. But anyway I tried it and I bought it, and I can say it worth it.
The guide will not tell you how to become rich without working, it gives you some tips to work more efficiently. Even if you are experienced with Android, you can learn some useful stuff from it. Take into account that you will need to know something about programming to take profit of it.
Google Play has changed a lot recently and my apps are not working so well as they used to. Maybe the same happened with ramzixp’s apps, and he made this guide to compensate. Anyway, I’m growing again than you to this guide so i can assure that it is not scam or a shitty guide with very basic information.
