Dragon Vision can track thousands of very small movements within a video recording making it an excellent tool for Vibration Analysis as well as Phase Analysis. Additionally, recorded vibrations can be played back with an amplified and slowed motion to observe the real deformations on a machine. FFT resolution will depend on the length of the video. Max Frequency will depend on the frame rate of your recording (0.5 x Frame Rate). Thus, you will be able to see vibrations up to 120 Hz (7200 CPM). ## Key features - Track small movements in video - Vibration analysis - Phase analysis - Amplified and slowed motion playback - Observe machine deformations - FFT resolution based on video length - Max frequency up to 120 Hz ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | Annual Subscription | $749.00 | per year | ## Recent user reviews (5 of 5) All indexed reviews: https://appshunter.io/ios/app/dragon-vision/id1515160633/reviews.md ### 1/5 — Run Away *2023-01-26* Who will pay $300 for a non working app? You can’t test it to see if it really does what it’s supposed to do. App was made to fail!!! ### 1/5 — Non-functional without an expensive subscription *2022-12-09* If I could rate Zero stars I would. All it can do is record a video and crash. There is no functionality to test capabilities without paying several hundred dollars. Last updated two years ago. Zero confidence this would be worth $5, much less an on-going annual subscription. ### 5/5 — Incredibly powerful *2022-10-25* Very intuitive but should be a timed trial with full functions rather than having to buy it first ### 1/5 — DON’T DOWNLOAD! It is UNUSABLE!!! *2021-10-08* The point of a “free” app is to get your customers interested in your program. One clip recording and no targeting available without subscription is not a working app, it is a work in progress. Fix the demo app to allow minimal targeting and short clip viewing. If we can’t see what we are paying for, we will take our money elsewhere! If it cannot even be tested without a $300 annual subscription it will fail! ### 1/5 — Completely useless without a subscription *2021-07-06* Why did I even download the app if it does nothing? There has to be a demo mode where I can play around with it and only subscribe if I want to use it professionally. ## Frequently asked questions about Dragon Vision ### What is Dragon Vision used for? Dragon Vision is used for analyzing video recordings to track very small movements, which is excellent for vibration analysis and phase analysis. It allows users to observe amplified and slowed-down vibrations to study deformations on machines. ### How does Dragon Vision handle FFT resolution? The FFT resolution in Dragon Vision depends on the length of the video recording. Longer videos will provide higher FFT resolution for more detailed analysis. ### What is the maximum frequency Dragon Vision can detect? The maximum frequency Dragon Vision can detect is 0.5 times the frame rate of your recording. This means you can see vibrations up to 120 Hz (7200 CPM) with appropriate frame rates. ### Is Dragon Vision free to use? Dragon Vision is free to download and use. However, it does offer in-app purchases, which may include features or advanced functionalities. ### Does Dragon Vision have ads? No, Dragon Vision does not contain advertisements. The application is ad-free, allowing for an uninterrupted analysis experience. ### What devices is Dragon Vision compatible with? Dragon Vision is compatible with iPhone, iPad, and iPod devices.
