52 vs OTrip vs Stamped: Which Travel Passport App Fits You
The "digital passport" idea — a stamp for every place you've been — has a few apps chasing it now. Three worth comparing are 52, OTrip, and Stamped. They overlap in spirit but differ in how a stamp gets earned, which is the thing that actually shapes how the app feels to use.
Here's an honest look at where each one fits.
The quick version
- 52 reads the photos already on your phone, groups them into trips, and stamps every place — automatically, retroactively, and on-device.
- OTrip is the closest in approach: by its own description, it reads dates and cities from your camera roll on-device and proposes the trips you forgot to log.
- Stamped leans on GPS verification — according to its marketing, you collect a country stamp by being physically there, alongside a fill-in world map and per-trip photos and journals.
| 52 | OTrip | Stamped | |
|---|---|---|---|
| How a place gets stamped | From photos you already took | From photos in your camera roll | GPS verification on location |
| Works retroactively (past trips) | Yes | Yes | Limited — favors being present |
| Needs you to be there with GPS on | No | No | Yes |
| On-device / private | Yes | Yes (per its marketing) | Varies |
| Auto-detects trips, holidays & birthdays | Yes | Trip detection | Manual trip entries |
| Separates home life from travel | Yes — home-area filtering | — | — |
| Map with % of world explored | Yes | Atlas view | World map |

52 vs Stamped: earned from photos vs earned on location
The clearest contrast is with Stamped. Its GPS-verified model means a stamp is proof you were physically standing there — which is a nice guarantee, but it has a real limitation: it favors stamping places going forward, while you're there with the app open. Trips you took before you installed it are hard to capture.
52 inverts that. Your photos already prove you were there, so 52 stamps your past travel just as easily as your next trip. If most of your traveling happened before today, that retroactive coverage is the difference between a passport that's already full and one you have to fill from scratch.
52 vs OTrip: the close call
OTrip is the most similar app here — both read your camera roll on-device and reconstruct trips, so if you like that model you'll like both. Where 52 leans in:
- Home-area filtering — 52 learns where you live and keeps everyday photos out of your travel history, so your passport and map show genuine trips, not your daily commute.
- Meaningful moments — beyond plain trips, 52 surfaces holidays and birthdays spent away from home.
- The "52 weeks" idea — 52 is built around the philosophy of making every week of your year count, not just logging stamps.
We'd genuinely encourage trying both; they're close, and the right one is the one whose feel you prefer.
The bottom line
- Pick Stamped if you want GPS-verified, "I was physically here" stamps and you'll mostly collect them going forward.
- Pick OTrip or 52 if you want your passport built automatically from the photos already on your phone, including years of past travel.
- Pick 52 in particular if you want home-vs-travel filtering, automatic holiday and birthday moments, and a map and passport that fill themselves in — all on-device.
