Make every training satisfying and effective!

Improve your performance with Video Delay Instant Replay in just 4 steps:
1. set a delay time for your exercise
2. do your action
3. watch video feedback
4. correct your form

Coaches and teachers! Use the app with a TV screen to watch the Replay with your team! Analyze your players' performance and correct errors. “Draw” lines on the screen to check out the angles. Edit the Replay, so it only shows what you want your students to concentrate on. Instant Feedback also helps to settle disputes between players.

Basketball players! Take a quick look at the footage, correct your posture, and get right back to the action. No need to rewind or touch the device, the video will play instantly. This way you can improve your shooting form by copying your favorite NBA players. Also, you will be able to see if you are low enough on your legs or if your fake moves are effective.

Golf or tennis players! Use a motion-detection grid and correct your swing or backhand instantly! Perform proper movements and maintain good posture while exercising. Build better muscle memory and improve your game!

Training martial arts, archery, or shooting? Study your form with delayed video. Set a very short delay time and analyze your moves in slow motion. See what to correct in your kicks or punches.

Pilates or yoga fan? Check out poses, that you won’t see in the mirror, like dog or pigeon. Make sure you are true to form and protect yourself from injury.


Set delay time by using the Clock button or by tapping on the screen when beginning and ending the task.

Delay Mode plays buffered video after a selected time. In the down right corner, you can see real-time capture. In this mode, you can replay your actions and save them as a video file.

Slow-motion Mode plays buffered video in slow-motion. It works only for short-time exercises (about 3 sec), like shooting or jumping. To adjust the zoom or slow-motion ratio use the slider on the top.

Replay Mode lets you analyze your moves step by step. Select part of the replay you would like to examine with the A, B, and Zoom buttons. Touch the screen to add lines and check out the angle. Save your replay as a video file.

With Grid Mode you can add movement detecting lines on top of the camera view. To change the number of columns/rows go to settings. Use a pencil button to open edit mode and slide the lines or adjust the movement detector’s sensitivity.

You can set as long a camera delay time as your device memory allows you. Lower your camera resolution in settings in case you need a longer delay time.

What’s New

Version 2.1.10

When the buffer is set, the replay and toggle camera buttons are disabled, to prevent tapping on the accidentally (if you want to open replay screen or start recording).

Swim Team

I use this app when my swimmers are working on their starts and finishes. I’ve been able to connectTo the television using using Apple TV. When we don’t have the Apple TV available, we connect to the television using an HDM I cable and an iPhone adapter. Works like a charm. If I don’t have a TV available for playback, the phone works fine. I also have the iPad version as well. All of the different devices work great on their respective platforms. I have no regrets purchasing the pro version of this app.

Perfect for coaching diving

I coach a dive team, and this app has been awesome for providing the divers and me with quick feedback. With buffered mode I'm able to save the dive after they perform it, and the delay continues which is unique among the delayed video apps I've tried. For my use case (short delay of 15 seconds or so, with ability to save for later analysis), it does the job very well. The development team has also been very helpful with questions and feature requests!

Is not worth the money

I am really disappointed in this app. I tried the free version, and it worked ok, and I saw this version thinking it would be way better then the free version. Honestly this app is a scam, it seems to be glitchy sometimes and it has some features that I think I would never need to use. Like the screen flip or the camera rotation, or the screen lock like why would I need to lock the screen. And why would I need the buffer length to be 125 seconds. I also wish they would have a simple guide to use some of the features on this app. I am really annoyed at how much money this thing is selling for, it honestly isn’t any better then the free version.

Hi, sorry to hear that you can't find any use for our app. People mostly use it to get video feedback (delayed mirror) during the training session. Some of the features you've mentioned are no longer necessary and you would not find them in the newest version. The screen lock is useful when training a bunch of kids that can't resist touching the screen (and changing the settings). The simple instruction on how to use the VDIR app is on our website. The PRO version is ADS FREE, thats the different. Hope this was helpful.
