InfoGap is an offline decision-interruption app that helps you spot missing information before you commit to action. Instead of rushing to a final choice, each Gap Run guides you through a fixed sequence: review one incomplete scenario, identify exactly three missing facts, choose one Critical Unknown, explain why it matters, and record your Action Stance and Readiness State. Every completed run is saved as a locked, read-only Gap Card so your original judgment stays intact. When you want to test how one resolved fact might change your next move, use Shift Check to create a linked revision and compare before-and-after decision states. InfoGap is fully offline and private by design. All cards stay on your device. No account, no ads, no analytics, no tracking, and no cloud dependency. Best for students, professionals, and everyday decision makers who want stronger uncertainty awareness and better commitment timing.
