Come on now. Both apps are FREE. Why not just test both of them out for a few minutes each then decide after? Each person has their own personal preference, so my preferences and your preferences might not be the same.
Thanks for your reply. I'm developer of Coinmarket and I want to know the sense of different trader when using both of them. 
Oh. My bad. You shouldv'e stated that on your post.
Anyway, looking at your app, it looks like your app is really similar to TabTrader. But personally, I would still use TabTrader. Why you say? Simply because I find TabTrader more trusted. For me to use your app, you'd have to provide a good kick-ass feature that TabTrader doesn't have.
Thanks for your feedback. It's really worth it.
