Garage Life
Garage Life was the first app put out by Corgrimm Tech. I thought it would be a good idea to start with. It is a basic no network, database driven app. You can add your vehicles and keep track of the maintenance logs. Garage Life was a good way to learn the ins and outs of how an app is supposed to work with a database.
Another fun feature that I added to this app is the ability to send fuel reports to the popular mileage tracking site, Fuelly.com. At the time that I developed the app (and I believe currently) there was no public API for this site. I also was not a very big fan of using mobile web for something that should be a simple and fast thing. One thing Fuelly has is the ability to send updates via SMS message. I created a form that would allow you to enter your fuel fill information and press Save. In the setings, you could set it so that your phone would automatically send an SMS to the Fuelly servers or you could have a separate button for sending. There is a little bit of setup on your Fuelly account in order to recognize SMS messages from your phone.
I had fun building this app and still use it today.
