With an innovative design and validated tracking algorithms, Calf Raise brings science to your practice! The Calf Raise (rise) or Heel Raise (rise) test is often used in clinical practice and research to assess the strength and endurance of the calf muscles. The test involves going up on your toes and back down as many times as you can. The test has excellent reliability and is able to detect side-to-side differences and injury deficits, especially when tracking more than just the number of raises! The Calf Raise app lets you do that. Want to measure power and work with an external load? No problem! Enter the additional load used to test strength more than endurance. Calf Raise is versatile to fit your testing needs. Calf Raise gives you detailed information on your Calf Raise (Heel Raise) performance using the camera on your iOS device. Calf Raise tracks the path of a circle placed on your heel and its full trajectory curve. With three simple clicks, you get total and peak heel height, power, and work! Calf Raise also calculates a fatigue index by comparing the first and last repetition, and provides a convenient place to record the total number completed! All you need to do is enter your details, record a repetitive Calf Raise performance, adjust the tracking marker, and select the start, first peak, and last peak, and voila! Do the test on the right and left legs to compare between sides and detect any asymmetries. FEATURES: • Videos. Record videos straight from the app or import as many as you like from your camera roll. • Metronome. Select your metronome: 30 Hz, 60 Hz, 120 Hz, or none • Additional load.

However, I find the app glitchy (crashed on me) and not exactly user friendly when making profiles for different patients. I have only tried recording within the app rather than submitting a video from my files. However, recording within the app is time consuming to get the final analysis I’m looking for when I have the patient in front of me. I wish this app was a bit more user friendly since it has great potential. ### 1/5 — Keeps crashing *2020-05-14, version 1.0* Seems like it could be a great tech tool for Physio’s, but kept crashing 👎🏻 ### 1/5 — Would not recommend *2020-05-11, version 1.0* Not very good. The apps keeps crashing and you need to edit the video all the time in order for software to properly track the movement of the foot. And when it cannot track, the app just shuts down. Bottom line, the app needs more work ## Frequently asked questions about Calf Raise ### How does Calf Raise measure performance?
