A native iPhone focus app
One frame.
However long you stay.
Commit one photograph, then stay while it develops under safelight. Switch away past the eight-second grace period and light can fog the print.
Follow Darkroom on XPhotos and session records stay on your iPhone in v1.
The ritual
Compose. Stay. Keep.
- 01 / COMPOSE
Compose one frame
Choose the view before starting. Once the session begins, there is no retake.
- 02 / STAY
Let time develop it
Progress follows wall-clock time while the committed photograph comes up.
- 03 / KEEP
Keep what happened
Damaged and abandoned session records remain in local app storage.
The photograph is the timer
Watch the print come up.
The same committed frame moves from safelight to neutral reveal as the planned session elapses. There is no abstract progress ring to finish instead.

Light leaves a mark
Eight seconds are free. After that, light gets in.
Switch away and return inside the grace period without damage. Stay away longer, and only the absence before the planned end can fog the frame.

Local by design
The photograph stays with the phone.
Photos and session records stay on your iPhone in v1.
Darkroom has no account, photo backend, or sync service. The session record belongs to the device where it was made.
