About this app

ZestCam turns your iPhone into a professional camera for OBS. Stream a clean 4K picture over Wi‑Fi with SRT, or send it over USB and HDMI. No watermark and no on-screen controls in your shot.

TWO WAYS TO CONNECT

• Wireless SRT: stream over your local Wi‑Fi straight into an OBS Media Source. Encrypted, low latency, no capture card needed.

• USB and HDMI: connect the iPhone to your computer or a capture card. The screen becomes a clean full-screen feed and the controls hide themselves. On HDMI, the phone's own screen dims.

PRO IMAGE QUALITY

• Up to 4K at 60 fps, plus 4K30, 1080p60 and 1080p30, depending on your iPhone.

• Picks the best camera format automatically, with video stabilization.

• H.264 or HEVC. HEVC uses about a third less bandwidth at the same quality.

• The picture follows how you hold the phone, in landscape or portrait.…

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
