Trek is a personal travel journal with built-in expense tracking. Tap "I'm here" at each stop, snap a photo, log the cost. At the end of the trip you get a timeline, a map, and the total spend.
Travel with a group? Everyone logs their own stops — Trek auto-settles who owes whom (Splitwise-style). Share any trip as a public link. No auto-GPS, no social feed, no itinerary planning. One free trip forever; €19.99/yr unlocks unlimited.
