Android 4.0+: Check out BarSense – a simple bar path tracking app.
Useful not just for weightlifting, but also for squats (see examples here) and all your other favorite lifts. The developer is taking your feedback in this reddit thread.

Great app, used it on all my lifters tonight, gave them some quick/instant feedback on their lifts.
Price: Free!
Download: BarSense on Google Play
Features:
- paint bar path
- calculate bar velocity
Premium Features: 1.49 Euros in App Purchase give you

Cool, I’ll give it a shot. I hope it doesn’t require the video to be taken from a perfect angle or anything because it’s damn near impossible to prop my phone up to record as it is.
That might be an issue. Gorilla Pods for the rescue http://joby.com/gorillapod
cant wait to try it
Decent app for bar path tracking, but the bar velocity is completely off
even if the m/s isn’t really accurate, at least you have a relative measure of bar speed, ie doing dynamic effort work, you know when you have begun to slow down, either due to load or fatigue.
Comparing one lift to another speed wise in a basically binary way (faster/slower) is still a helpful tool
Yeah, thats true. Looking at the speed-curve is very useful indeed!
Apple. Need for apple
Protein shake is better than apple

Don’t let Coach’s Eye get a hold of this or you’re done. This is a sick app. Love it! Need it for Apple tho. Nice job creating this!
Nice development and very practical . As a biomechanist I am a little be worry about how the application read the real distance necessary to calculate velocity if I do not use any 2d spatial frame to scale in the area of motion
