Opportunity score
46/100
A real problem with a focused solution, but the generic niche, one-time pricing, and lack of demonstrated traction limit startup-scale opportunity.
Founder verdict
MAYBE
A well-positioned, privacy-friendly niche tool with a real cognitive bias problem but unproven traction and limited generic startup upside.
What is Reckon?
Reckon is an indie iOS/iPadOS decision journal that structures predictions, confidence levels, check-ins, and outcomes to show how well-calibrated a user's judgment is. It is built by a sole developer, uses iCloud sync instead of a backend, and charges once on the App Store. The product occupies a specific niche between personal productivity and rational decision-making, with no public revenue, growth, or user count disclosed.
