MinTrip turns a trip with friends into a game. One private, invite-only app for the whole crew — a photo feed with points, an AI stamp book that reads real ink, metro-map itineraries that show where your paths cross, and offline mountain trails on iPhone and Apple Watch.
Every trip is its own invitation-only space. No public profiles, no ads, no strangers — just your people, your days, your inside jokes, kept forever.
Photos and videos land in the trip's own feed — and earn points. Check-ins, reactions, comments, daily FLASH moments, and a leaderboard that crowns one champion. It's a social network with a guest list of your best people.

Stations, temples, and museums across Japan (and beyond) hide real rubber stamps — eki-stamps and goshuin. Photograph the ink and AI identifies the stamp, names it, scores it, and verifies you pressed it at the real spot for bonus points. It even scouts stampable places within walking distance. Half scavenger hunt, half souvenir you keep forever.

Everyone pastes their own plan — AI reads it and draws the whole group as a metro map. See exactly where your line crosses your friends', then turn a crossing into a dinner with one tap.

Full mountain guides that work with zero signal: elevation profiles, shrines, viewpoints, water stops, and your live pace. Download before you climb; the mountain doesn't need Wi-Fi. MinTrip launches with the Kumano Kodo pilgrimage (Nakahechi route); more trails join on the same interface.
⌚ Apple Watch app included — the whole trail guide, elevation, and live pace right on your wrist, phone in your pocket.

MinTrip is the opposite of a social network that happens to do trips — it's your trip, with the network kept out.
