shotdiagnostic.com runs without paywalls or email capture. Hosting, weather data, and development come out of pocket.
If the tools have helped, an optional contribution via Ko-fi is welcome at ko-fi.com/shotdiagnostic in any currency. Every tool on the site — the diagnostic assessment, the calibrated target builder, range atmospherics, DOPE cards, the learn explainer, and the insights dashboard — is free for everyone regardless.
Independent project. One person, zero paywall. Feedback always welcome at hello@shotdiagnostic.com.
