Twinkle is Twitter for your iphone. The interface looks simple and beautiful. Their “sales page” also features functionality videos. If you’re gonna pay for it… you might as well know you’re gonna get. I’ve already been seeing some people tweeting on my twitter feed via this application and no complaints from them.
Great execution always sit well with me. Tapulous.com proves exactly that one their site. They might not have tons of applications, but what they do have looks great, and fun.
