I am developer with 5 years experience. I have examined all codes on codecanyon available for creating a chat app, I love this for many reasons. It has all features there is on WhatsApp and yet this app was made with Android studio, which means it can easily be used by anyone, and fully documented to help us set it up, while many are using flutter or vs (Xamarin) the author made something that can compete with WhatsApp with Android studio, yet it's affordable.I love android studio, and so I love this app.The code are 100% bug free, tried many others, one fault here or there, or one thing missing, if I write how much quality there is in this code, I am sure I will be writing more than 5000 words, I write this review to encourage the author to keep going.. you guys are too good, you are friendly too and real experts in this.
