Video Stream Delay

Use your built-in camera as a delayed video mirror or a GoPro for instant technique review during training.

Video Stream Delay helps athletes, coaches, and solo users review movement immediately after it happens.

Set up your GoPro or use the built-in iPhone/iPad camera, choose a delay, and watch your technique a few seconds behind live. Finish a swim lap, climbing move, lift, serve, jump, swing, or drill, then look at the screen and instantly see what just happened.

No scrubbing. No handing the phone to someone else. No stopping the session.

How you can use it: Place a GoPro on a tripod, wall mount, pool deck, gym corner, or hard-to-reach angle. Keep your iPhone or iPad where you can see it. The app shows the camera feed with a delay, so you can review your form right after each attempt.

Or use the built-in camera when you want a fast setup for solo practice, coaching, warmups, or technique checks.

Built for:

• Swimming and pool training
• Climbing and bouldering
• Gym sessions and lifting form
• Volleyball, tennis, golf, baseball, and field drills
