About this app

Free to download, with a new Daily Journey every day. The full game is a single purchase, no subscription.

Trailmarks is a travel trivia game built on the real world. You answer true-or-false questions about the city you're in, collect the rewards, and put them toward a ticket out. Where you can go depends on what you can afford, what the departure board offers, and how much risk you want to take.

Your score is the kilometers behind you when you run out of nerve or mood. A run usually fits one sitting, though a good one keeps going, and you can put it down and come back whenever.

THE DAILY JOURNEY

Every day, everyone gets the same run: the same start city, the same cards, one attempt. Some days begin where something is happening, like Syttende mai in Oslo or Diwali in Jaipur, and some change the rules. Compare your distance on the daily leaderboard.…

Version 1.4 · 2026-10-09
Share your Daily Journey: when you finish today's journey, send your route map to friends and see how far they get. • The route map now draws trips across the Pacific properly, and long flights follow their real great-circle routes • A new opening screen: the window seat on a night flight • Fixes text that was cut off on the Japanese ticket desk Made for iPhone Duo. Open it up and your route map stands beside the deck, drawing each trip as you travel. After a run the finished route sits next to your results, and your achievements stay in view on the departures board.

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
