I want to suggest to change the look of your app, like it looks now is not really stunning. It's a T in a text balloon that is cutted at the sides. And light blue and white aren't the most beautiful colors.. (also it looks like a copy of fb messenger app..). :) It works great and once you open the app Textra all looks very nice to, I couldn't know how to make it better! But that app logo with the T is really bad looking (sorry if I'm critical).

If the app logo would look better I would put it on my homescreen, but now it isn't.

I hope you put time in changing the design of your app itself, maybe make some new Textra logo's, make a poll of it and let Textra users vote on wich Textra app look they would like the most and wich they want to be in use in the future.

P.s.: I prefer a black/gold app look. ;)
