My Jump Lab is an app that combines My Jump 2, My Lift, Runmatic, My ROM, My Mocap, Nordics, Readiness, COD Timer and ForceData in a single app, making testing convenient, practical and affordable.

My Jump Lab app can measure more than 30 tests including jumping, lifting, running, sprinting, directional change or even markerless motion capture with accuracy comparable to expensive lab equipment for just €3.99/month, €29.99/year or €99.99 forever, including a 7-day free trial.

This app can be easily used by coaches, athletes, physiotherapists and researchers. Most of these applications are reliable and valid (if you want to know what that means, click here), which is not often the case. Validity and reliability (if you want to know what it means, click here) have been tested and published in scientific papers:

My Jump 2 takes advantage of the device's high-speed camera to record stunning slow-motion videos of jumps. You have to select the start and contact frames and My Jump 2 will give a reliable and valid jump height. My Jump 2 also measures the force, speed and power profile of jumps, as well as other relevant variables such as contact time, vertical stiffness or reactive strength index in a simple and accurate way.

Runmatic (which has been presented last month on our website: takes advance of the slow-motion recording capabilities of the latest iOS devices (iPhone, iPad mini, and iPad Air) to accurately analyse steps while running. Using scientifically validation equations, Runmatic calculates the contact-flight times, force, efficiency, frequency and even the asymmetry of legs in a simple, accurate way.

My Lift enables to estimate the 1-RM: you just need to record one repetition of the desired exercise with 1 to 4 different submaximal loads and select its start and end with its accurate frame-by-frame navigation. Performing an actual 1-RM test could be dangerous and fatiguing and, if performed every day, it will most likely lead to overtraining or injury. To solve this problem, My Lift uses scientifically validated algorithms that can estimate 1-RM with high accuracy by simply recording your exercise.


Nordics is an app specifically designed to monitor performance in the Nordic Hamstring Exercise. The app measures with high accuracy the breakpoint angle achieved in the Nordic Hamstring Exercise, based on recent research showing that this angle is highly related to eccentric hamstring strength.

MyROM can measure dorsiflexion angle and ROM of many more body joints using the advanced gyroscope on your iPhone or iPad. MyROM calculates ROM angle variables such as dorsiflexion, hip internal rotation, etc.

ForceData is an app that uses the sensors of the iPhone and iPad to measure acceleration and force. Also, it exports RAW data to a CSV file as well as low-pass filtered data and Kalman filtered data.

Ace Workout uses advanced algorithms to create daily randomised workouts from a database of millions of routines. It combines more than 90 pulling and pushing exercises to work your muscles in a balanced way and randomly selects the number of reps per set of the session.

With Readiness, you can assess your well-being with a questionnaire from your iPhone or iPad. It generates a Readiness score on a scale of 1 to 9 based on perceived sleep quality, muscle soreness, fatigue and stress. It then compares daily scores with the average of the previous two months using a very intuitive traffic light system: green is ok, orange is moderate fatigue and red is severe fatigue.

COD can assess velocity, contact time, leg asymmetry or Change Of Direction deficit.

My Mocap allows to measure dynamic knee valgus, squat depth and many more in real time. It uses cutting-edge Augmented Reality and Machine Learning algorithms to measure body joints in real time. You need to point to your athlete with your camera to conduct different tests.

Interview with Carlos Balsalobre, founder of My Jump Lab, who won the price of the best innovation in sport science at the Sport Innovation Summit in Paris (2018).

- Can you present who you are?


My name is Carlos Balsalobre and I’m a professor in biomechanics and sports technology at the Autonomous University of Madrid. I’m also consulting elite athletes in their strength training programs (right now I’m working with olympic runners) and I’m also an app developer.


- Why did you create MyJump Lab?

 During my PhD i had very little resources to measure physical performance because the lab of my Uni was not so good at the moment, and borrowing the few devices they had was complex. I was always thinking about cheaper and more portable alternatives to make my job easier, and soon I realized that many (actually, most) practitioners in the field had the same problem than me. Lab equipment is expensive and only a few can access to them. So, when Apple released the first iPhone with slow motion cameras I had the idea to create an app to measure jump height from a simple video analysis, since it was well established that professional slow motion video analysis was a valid and accurate tool to measure performance. I decided to learn how to code apps and to create an app to measure jump height by measuring the flight time with the slow motion camera on the iPhone. Then, other apps came after that to measure runs, sprints, barbell velocity…I’ve always tried to democratise the use of technology to measure performance.

- What is your current team and the collaborators?

It’s actually just me, so I don’t have a team or collaborators working with the app. I do the programming, the design, the conceptualisation…However I’m always trying to learn from great scientists, coaches and practitioners that ultimately inspire me to make my app better. 

- Which problem does My Jump Lab answer?

It’s big goal is to democratise the use of technology to measure sports performance (specially, jump tests, sprints, running mechanics or barbell velocity), no matter the budget of the practitioner. Also, another big problem it solves is how to measure performance remotely. Thanks to it’s video analysis capabilities, coaches can analyze performance of their athletes just from a video they send them over via WhatsApp or similar. This was specially important during the pandemic since athletes couldn’t come to the training center, but they could always record themselves at home and send the video to the coach. 

- What are your successes?

I love to see my app being downloaded in countries with really low resources. It’s actually being used in more than 100 countries worldwide, and total downloads are something about 200k. However, I was also surprised to see many elite organisations including EPL, LaLiga, NBA or olympic teams using the app because it’s very convenient during travels or for quick on field assessment when calibrating and preparing lab equipment is not an option. It’s not like it’ the TikTok app, but it’s kind of popular in the field.

- What are the next steps for the development of your app?

To be honest, I don’t know! I’m always looking at the industry and seeing how it evolves, since the app is just a software that takes advantage of the available hardware. For example, over the past couple of years I made important updates that took advantage of the increasing artificial intelligence capabilities of the smartphones to make things that were impossible just a few years ago, like markerless real time jump or barbell detection. The next big thing, in my opinion, and where I think the app would evolve in the near future is the use of augmented reality. For example, I’m already testing the app in the recently announced Vision Pro mixed reality technology. 

- Do you have some scientific publications validating MyJump Lab?

Yes, actually many! You can just go to my researchgate profile ( and read them. I’ve always been almost obsessed with validating my apps, and I actually think that the popularity of the app is because it’s backed by more than 10 scientific papers. Also, I’m grateful that many independent teams worldwide not related to me in any way have validated to app by themselves. It helps increasing transparency.

- What is the best way to contact you for the potential investors or the potential customers?
