I'll definitly take a closer look if you release more interesting pricing tiers for us.
Your product look awesome, and well documented.
Too bad there's not a simple way to test iOS apps on Windows (not your fault, of course ^^)
Trigger.io looks very nice but I totally agree with you, the 50$/month is really a huge issue for indie dev who just want to play around with iPhone app making.
You can't just release an app with a huge ad at each start, even if it's just for fun :/
Seems more complete and visually engaging than the others to me.
Very well done.
Although a hosted version like documentup could be really great too for open source projects
