What I'm building

  • Estimatey

    EstiMatey is a simple estimation tool that helps users understand the possible cost, development time, and complexity of an app or system idea. Users answer a few questions about what they want to build, and EstiMatey provides an initial estimate to help them plan before starting development.

  • LaunchBox

    LaunchBox is an idea-planning and validation tool that helps users turn a rough app or product idea into a clear first plan. It helps users decide what to build first, what can wait, what to validate, and what their next steps should be before investing time and money in development.
