Custom Data Organizer

My buddy's kid turned 16 recently, got his license, bought a car on Craigslist. The car came with a notebook. The owner had recorded every bit of maintenance, every oil change, even every gas fill-up, complete with mileage, gallons, and prices. And I thought, this is the type of person I built http://CustomD.app for. My dad did this kind of thing when I was a kid. Kept logs, calculated gas mileage, route times into town, and logged every detail of his bicycle trips. He is sort of what inspired this thing I built. In traditional app design, you can't make something that meets the specific needs of these types of folks, since they are each trying to record things in their own unique way. Until now they've been stuck with pen and paper or a cold, boring, and impersonal spreadsheet. I need to find these people and show them how much quicker, easier, more shareable, and automated it can be with my app.
