GoPro's HindSight captures 15 or 30 seconds of video from before you press record, but only on the camera itself, and it disarms after 15 idle minutes. To get the same pre-recording mechanic on an iPhone, use a buffer camera app. Video Buffer Action Camera holds up to 100 seconds of pre-roll and stays armed for as long as the app is open, with no extra hardware to carry or charge. To be clear: the app does not connect to or control a GoPro. It records with your iPhone's own cameras and replaces the need to carry one for this job.
Does the iPhone have HindSight built in?
No. There is no HindSight setting in Apple's Camera app, and iOS has no system-level pre-record mode. The closest thing Apple ships is a Live Photo, which keeps about 1.5 seconds either side of the shutter, and that is far too short to catch a goal, a trick, or a jump you reacted to a moment late. HindSight itself is GoPro's own camera feature, so it only exists on GoPro hardware.
To get the mechanic on an iPhone you need a third-party buffer camera app, which keeps a rolling window of the recent past in memory and writes it to a file when you tap. That is the category to search for, and it is what this app does.
What HindSight actually does
HindSight arrived with the HERO9 Black and it is a genuinely great idea. With HindSight armed, the camera continuously captures video into memory without saving anything. When you press the shutter, the file that gets written starts 15 or 30 seconds in the past, whichever you chose. You stop reacting to moments and start confirming them after they happen.
The catch is in the fine print. HindSight only works while the camera is on and actively buffering, so it drains the battery roughly as fast as normal recording does. And to protect that battery, GoPro makes HindSight switch itself off after 15 minutes without a capture. That timeout is one of the most common complaints on GoPro's own forums, because unpredictable moments are exactly the ones that take longer than 15 minutes to show up. You wait 40 minutes for the eagle, the eagle finally dives, and HindSight quietly disarmed itself 25 minutes ago.
The same mechanic on the phone in your pocket
There is nothing magic about the hardware here. A rolling buffer is software: capture continuously into memory, discard the oldest frames, and write a file only when asked. Your iPhone can run that loop all afternoon. A buffer camera app gives you the HindSight workflow with a few practical differences:
- Up to 100 seconds of pre-roll instead of a 30-second maximum. Long build-ups, full plays, and slow-developing moments fit in the buffer.
- No idle timeout. The buffer stays armed for as long as the app is open on screen, whether the moment comes in minute 2 or minute 90.
- No second device. Nothing extra to buy, mount, charge, or forget at home.
- Instant sharing. Clips land in Photos, the Files app, or iCloud Drive, ready to send from the phone that shot them. No card, no offload, no companion-app transfer.
How to set it up on iPhone
- Open Video Buffer Action Camera and tap the clock button to open Buffer duration.
- Pick your pre-roll length, anywhere from 2 to 100 seconds. The central record button shows the number, so you always know how far back a tap will reach.
- Point the phone at the action and wait. The screen stays awake, and nothing is written to storage while you wait.
- When the moment happens, tap record, tap anywhere on the screen, or press a volume button. The saved clip starts your chosen number of seconds in the past.
- Want HindSight-style one-press captures? Turn on Save Buffer Only in Settings and each tap saves just the pre-roll and rearms automatically.
You also get triggers a GoPro does not offer in this situation. Pair the Apple Watch companion and you can fire the buffer from your wrist while the phone sits on a tripod. And Dual Camera mode records the front and back cameras at once, so you can capture the moment and your reaction to it in the same clip. Short buffers are free to use, and longer buffers are part of the premium subscription.
Where the GoPro still wins
Honesty matters here. A GoPro is waterproof, rugged, and mounts on a helmet, a chest harness, a surfboard, or a roll cage. You should not strap your iPhone to any of those. If your footage happens underwater, in the crash zone, or on your head, the action camera is the right tool and HindSight's limits are the price of admission.
The buffer app is for the other 90 percent of moments: the sideline, the park, the backyard, the trail viewpoint, anywhere you would be filming with your phone anyway. If what you want is the HindSight mechanic without carrying an action camera, and without the 30-second cap or the 15-minute countdown, the phone does it better.
Do this in Video Buffer Action Camera
Everything above is built in: a rolling buffer of 2 to 100 seconds, the Buffer duration picker, Save Buffer Only for one-tap HindSight-style captures, Multiple Buffer Times for three record buttons with different pre-roll lengths, Dual Camera front-and-back recording, and an Apple Watch remote. Record in 4K or at 240 fps slow motion, and save to Photos, Files, or iCloud Drive.
