一点也不好用
千万别下载，白花38元，一点也不好用，只能得出图像形状，不能调节坐标，不能使用数据运算，啥啥也不好用，鸡肋，差评差评差评！！！！
能力局限

好用！ 对于physcis 1 final pbl
Poor app
Very hard to use, expensive for what? Overall a mid product and not worth my money
Keeps losing object
It keeps losing a clearly marked object of different color from the background. It would be useful to have some control over the following sensitivity and color filtering. It should be straight forward not to lose a red dot moving over a white background.
No useful data export
There is no csv or any other useful data export. Useless for school experiments!

Scaling and timing issues
Fine if the app were free, but pretty unacceptable issues for a paid app.
This app seems pretty easy to use which is great, but the inability to set the scale to something other than 1 m makes it very inflexible. You can’t really investigate what is happening if you are investigating anything smaller than a meter, and if you are looking at things much larger you can only set a scale of 1m which increases the uncertainty of the measurements.
Furthermore, there is not an ability to do time delay which makes this even less useful. You should be able to set the time origin in sync with the first video analysis point. These things really need to get fixed.

Good for teaching physics
Only issue is that tracking seems too sensitive and loses the object very easily.
If I input position manually every few frames I can get nice plots to analyse.

Easy-to-use
I’m a chemistry teacher who uses many Vernier products in class and I also coach pole vault. I started using this with my athletes to analyze their run so I can show them what I see by eye. I just really wish we could change the axis options as x velocity vs x position would help show them more accurately the set-up at take-off. This would greatly improve efficiency and effective coaching as I need to export into the graphical analysis app. This change would speed up my analysis! As others mention, the tracking feature doesn’t work well for me either as I’m analyzing running mechanics.

Crashes every time
Trying to use any video than the example videos and this app crashes every single time immediately.
Don’t buy
Really old tech here. Doesn’t easily work - maybe on super simple applications like the ball drop example. The tracking is not usable for anything beyond the simple examples shown for a basic lab experiment.
Fantastic the Best for teaching physics
Tracking need to be done with a special care. Make video that way you have high contrast between tracking object and the background
My Opinion
This app is a useful tool when conducting experiments, but doesn’t create data tables..
Crashes on the iPhone X
Very disappointed
Cool good app worth $5
Actually very good! This app has very unique features I thought a mobile device couldn’t do! I could recommend to be able to add things the the tracking but it looks like you can draw if you track it on your finger!
Great app for $5, but also needs (free) Graphical Analysis app
Getting accurate results requires that you know what you’re doing, but if you do, then it’s great.
The auto tracking is meh, but manually adding data points is quick and easy.
Unfortunately, analyzing the data in this app is crap. Instead, download Vernier’s free Graphical Analysis app and import the data into that. Once the data is there, you can view x and y position and velocity data as well as do curve fitting.
All in all, well worth the money for a physics classroom.

"Object lost" all the time! Garbage!
