HitchPin: Oilfield Calendar

HitchPin is the oilfield hitch calendar that stays in sync. Set your rotation once — 14/14, 7/7, 14/21, or custom 1–90 days. HitchPin uses KeenCalc so ON/OFF days never drift. Today tells you if you’re ON or HOME, which day of the hitch you’re on, and when the next crew change hits. Home-screen widgets on day one. No paywall. Share a fridge QR so your spouse sees the same hitch — scan or paste, no account. • 14/14, 7/7, and custom hitches • Today: ON or HOME, day k of n, next crew change • Month and year view for Christmas, birthdays, and R&R years ahead • Widgets included • Spouse share via QR or payload • Year PDF for the fridge or glovebox • Fully offline. One hitch. No account, no ads, no subscription. Built for the patch.
