Was a user of Chomp SMS for years and loved the the ridiculous amount of customization available and themes and being able to tweak and customize the themes available or even make your own from scratch--During my use of Chomp I was using an old KitKat Device and just recently upgraded to the Nexus 6P and am on Oreo now and decided to switch SMS apps and try something new(hence why I started using Textra to begin with)...
