01
Perspective, corrected
Plumb uses shutter-time camera and motion evidence to create a natural, upright architectural photograph.
Architectural camera for iPhone
Keep the building
standing straight.
A camera made for architecture. Plumb captures the original, reads the phone's position at the shutter, and creates a perspective-corrected photograph—privately, on device.
On-device processing Original preserved
THE PRINCIPLE
Architecture is drawn with intention.
Photograph it the same way.
A small tilt of an iPhone can make parallel lines collapse inward. Plumb records the camera geometry at the instant of capture, then uses that evidence to form an upright image—without hiding the source frame.
The familiar frustration
A five-second tilt can become a twenty-minute fix.
Point a camera upward and the building starts to fall away. Vertical lines converge, façades lean, and careful compositions lose their balance. For architects and architectural photographers, the image no longer reflects the building they designed—or the one standing in front of them.
Geometry collapsesParallel edges converge and façades appear to lean.
Correction becomes a choreGuides, corner handles, rotation, crop—then another pass.
The frame gets sacrificedStraightening later can cut away the composition you wanted.
02
The original stays original
Every correction is a separate derivative. Your full camera capture remains intact and available.
03
Private by construction
Correction happens on your iPhone. Plumb does not upload captures to process them.
One capture. Two honest versions.
Corrected, never overwritten.

FAQ
What does Plumb correct?+
Plumb corrects converging verticals and architectural perspective caused by tilting the phone, while preserving a natural-looking composition.
Does Plumb replace my original photo?+
No. Plumb retains the original camera resource and writes the corrected image as a separate version.
Are my photos uploaded?+
No. Plumb is local-first: captures and perspective correction stay on your device unless you explicitly export or save a copy.
Which iPhones are supported?+
Plumb supports iOS 18 and later, with iPhone 13 or newer recommended. Available capture features adapt to each device.
In development for iPhone
Your verticals
are about to align.
Plumb is being prepared for its first release. The early access list is not open yet; TestFlight and launch details will be published here when they are ready.
