A field guide to the built world
Discover the
buildings around you.
Acarta is a social field guide for architecture, monuments, public art, and landscapes. Find what's around you, check in when you visit, and track what you've seen.
01 — Why Acarta
Every street is a catalogue.
Cities are the richest museums we have, and they're free. But without a guide, most of what's around you stays invisible — the façade you walk past, the sculpture in the square, the housing estate that quietly rewrote post-war Europe. Acarta turns the city into a field you can read: a place, a name, a year, a story. One check-in at a time.
Discover

Check-ins
A travel log for buildings.
Check in when you visit a place. Acarta confirms you were actually there, but lets you backdate a visit if you remember the year. Add your own photos and a short note. Private by default — share it when you want to.
- Verified at the moment of visit
- Backdate past visits
- Add photos and notes
- Public, friends-only, or private

Progress
Track the styles and eras you've seen.
Acarta keeps a running ledger of what you've visited — by architectural style, era, city, country, and creator. Twenty levels and around thirty-eight badges across four tiers reward range, not volume. Collect Bauhaus before you collect Brutalism. Earn a city badge by seeing the canon, not the postcards.

Social
Follow people whose taste you trust.
A feed of check-ins from friends and the people you follow. Comment, like, bookmark. No ads, no algorithm. You see what the people you chose chose to see.
Lists
Curate, collaborate, plan a trip.
Private folders for your own reference, collaborative lists you build with friends or share publicly. A shortlist for a weekend in Rome. A canon of interwar apartment blocks. A long list of places you want to see before you die.
Creators
The people behind the places.
Every architect, sculptor, and landscape artist has a profile: bio, dates, works, and linked nationalities. Tap a creator on any place and see everything else they made.
Cities
Over a hundred cities, from Stockholm to Kyoto.

FAQ
Questions, answered.
Is Acarta free? +
Yes. Browsing the map, checking in, earning XP and badges, and following friends is free. A small subscription unlocks power-user features like unlimited private folders, trip planning, and priority access to new cities.
Who makes the place data? +
Places are curated and verified by our team. Every image and fact keeps its attribution and license. Users can suggest edits and contribute photos.
Does Acarta track my location in the background? +
No. Location is only read when you press Check in, to confirm that you're actually at the place. It is not logged in the background, sold, or shared with advertisers.
Do you use my photos to train AI? +
No. Your photos, notes, and check-ins are not used to train machine learning or AI models, and we do not grant that right to any of our processors.
Can I use Acarta on the web? +
Yes. The full app runs on the web at acarta.app, in addition to iPhone and Android. Your check-ins sync across all three.
What languages does Acarta support? +
Acarta is available in English, Swedish, French, German, Spanish, Italian, Japanese, and Chinese, with more on the way.
