Turn your phone into a time machine
Stand where someone stood previously and take the same photo. Ephemeros lines the two up, and the time between them starts to move — a coastline retreating, a skyline rising, a garden filling in.
People are already tracking…
-
A building going up, groundbreaking to ribbon-cutting
-
A coastline eroding after every storm
-
A glacier's snowline creeping up the mountain
-
One tree through leaf-out, bloom and leaf-fall
-
Bare soil turning back into meadow
-
A vegetable patch from seed to harvest
-
A neglected building the council keeps forgetting
-
A favourite trail viewpoint in every season you missed
Whatever you pick, it's about 30 seconds a visit.
Find a spot near you
Open the map and you'll see spots — viewpoints other people have already photographed. Tap one and you're adding the next frame to a story someone else began. No setup: just show up and shoot.
The ghost does the hard part
The last photo floats over your camera as a see-through ghost, with live compass and tilt guides. Line up the skyline and you're within a degree of the original framing — we straighten the rest afterwards.
Then watch it move
Every capture joins the spot's series and rebuilds its timelapse automatically. Come back in a season and the thing you photographed is visibly, undeniably different. That's the moment people get hooked.
Start your own — and bring people with you
Found a view worth tracking? One baseline photo starts a new spot. Group spots into a list — your street, your reserve, your project — and invite friends, a class, or a whole community to keep it fed.
Only create spots where you have lawful access; get the landowner's permission on private land.
And it all counts for something
Every aligned series joins an open dataset researchers use to study environmental and urban change. Because photos are taken in-app, each one carries real location, orientation and weather — that's what turns a nice photo into evidence.
