I handcraft bespoke applications to suit your needs.
It's 4AM and you need some more alcohol but are in no state to leave your home. Bizzby allows you to post tasks that service providers can bid on. A taxi driver with your booze is on it's way!
Requester App is a small informal HTTP request maker for your iPhone. It allows you to enter in an endpoint and send a request to that website returning you its headers and response.
LinePeek is a social networking application which allows you to find venues (i.e. restaurants, cinemas) close to you and predict how long the queue is to get in.
Drive by UrbanFlowEngine is a small utility aimed at calculating fuel prices to venues near to your current location i.e. how much it would cost in fuel to travel to your local museum.
