Bifurca: Dual Video Recorder

One payment. Not a weekly subscription.

Record the moment once and walk away with two files: a 9:16 for Reels,
Stories and TikTok, and a 16:9 for YouTube. From the same instant — not
a crop made afterwards.

ONE SENSOR, NOT TWO LENSES

Bifurca captures a 4:3 frame and crops both formats out of it. That
matters more than it sounds: cameras that record with two lenses hand
you two videos shot from different viewpoints, with parallax between
them. Here both files are the same viewpoint, at the same instant,
carrying the same timestamp. Sync isn't "close enough" — it's exact.

And neither file is upscaled. The vertical one uses the sensor's full
height; the horizontal one uses its full width.

FOUR ASPECT RATIOS, NOT TWO

9:16 for Reels, Stories and TikTok. 16:9 for YouTube. 4:5 and 1:1 for
the Instagram feed. You pick which pair gets recorded.

Photos too, from the same shutter and the same two crops.

YOU SEE BOTH WHILE RECORDING

A live window shows the second format as you shoot, so both framings are
in front of you at once. Tap it and it swaps places with the viewfinder.

REAL CAMERA CONTROL

• Up to 4K, at 24, 30 or 60 frames per second
• 10-bit HDR where the device delivers it
• Stabilization: off, standard, cinematic or extended
• Tap to focus and expose, press and hold to lock
• Zoom to 10x, across the iPhone's real lenses

The app warns you before storage runs out and before the iPhone
overheats — and ends the recording with both files intact, instead of
being cut off mid-take by the system.

AFTER THE CAPTURE

Files go to the iPhone Photos library, where you expect to find them.
The in-app collection keeps both formats linked, which Photos doesn't
do, and plays them locked to the same instant — so you can compare what
each framing caught.

From there they go straight to Reels, Stories, Photos, or any app
through the system share sheet.

FIVE FREE CAPTURES

No quality feature is held back from them. 4K, HDR, all four aspect
ratios and stabilization all work without paying.

Bifurca Pro removes the limit. One payment, no subscription, no renewal
— valid on every device signed in to your App Store account.

PRIVACY

Your captures never leave the device. There is no server, no account, and
the files go straight to the iPhone Photos library.
The app sends only anonymous usage counts — which screen was opened,
whether the purchase happened. No Apple identifier, no cross-app tracking,
and you can turn it off in Settings with one tap.
