I made a simple prototype of my idea for a skateboarding trick logging system using a free mobile app that lets you setup databases. After trying to use it a bit, I've figured out that my idea for a web app that does the same thing would be very tedious to use without a lot of additional designing and engineering (learning on my part) in its current, rudimentary form. Yay for less expensive (in terms of time and effort) methods of testing ideas! I'll write up my learnings soon.
