I don't use Textra, I use the paid version of Handcent but I really don't mind spending a few bucks on an app that I really like. It gives the developer an incentive to continuously improve the app. I would say if you really like the app, pay the marginal amount to support the developer. It's nice having an ad free app.
I'm using the free version right now and I love it, just wondering if the full version is any different or better? Or does it just remove the ads?
May I ask......
What does Textra give / provide better than say the native text app already on the phone ?
