This is a project coming out straight out of #startups one late night. I came up with the idea (unfortunately found out that it wasn't original), but a bunch of guys helped me with the name (especially brownie), and hence PushPuppy was born.
Basically you can send any bookmark or snippet to your iOS device.
The iPhone app is written using Titanium and took me about 3 days to finish the core functionalities, and a few more days in total to refine and bug fixing. The web application is running on Rails 3 + MongoDB using Mongoid. The whole site was done in about 3 days.
The submission to Apple was quite straightforward. I submitted it late Friday last week, and it got approved late Thursday (6 days). Apple is getting faster with their approval process. My previous app, Marrily Mobile (http://marri.ly/marrilyapp), took an exact 7 days.
I hope it can save you guys time with the app. I'll attach the promo code next.
