Meydn vs TimeBack

Photograph buildings without the lean. Meydn corrects perspective in real time as you shoot, so keystone distortion is gone before you press the shutter. No editing afterward, no upload, no account. For architects checking their own work. For real estate agents whose listings need straight verticals. For photographers tired of pulling lines in post. For anyone who has watched a tall building lean on their phone screen and wondered why it has to. Meydn reads the building's geometry through your iPhone's lens, applies the correction in real time, and writes the result to your Photo Library. The original photo is saved alongside the corrected one, so nothing is lost. Features: • Real-time perspective correction (tilt-shift, keystone) • On-device computation, no internet required • Manual exposure, HEIC capture • Original + corrected saved side by side in Photos • No account, no analytics, no cloud, no third-party SDKs In 1867, while measuring Wetzlar Cathedral from a scaffold, the Prussian architect Albrecht Meydenbauer nearly fell. Buildings, he decided, should not have to be climbed to be measured. He invented photogrammetry. His method was simple: keep the sensor plane parallel to the building, and the geometry stays honest. From his glass plates to tilt-shift lenses to Meydn on the iPhone in your pocket, every architectural photograph whose verticals stay vertical descends from that idea.

DRIVING & DASHCAM Use TimeBack as a flexible camera with a replay buffer when you want to preserve something that just happened. Save recent footage without keeping every minute as a permanent video file. 【FAQ】 Q1: What is pre-recording?
 A: Pre-recording is TimeBack's core feature. The camera continuously buffers recent footage. When you press record, the buffered footage and live recording are saved together as one video, capturing the full moment before and after the action. Q2: Does pre-recording use a lot of storage?
 A: No. Buffered footage isn't continuously saved as video files. Only the footage you choose to record is saved. Otherwise, the buffer continuously overwrites itself, using less storage than recording continuously for a long time. Q3: Can I use TimeBack without pre-recording?
 A: Yes. TimeBack also works as a regular camera with 4K video recording, camera controls, and voice control. Simply turn off pre-recording when you don't need it.
