Step 1: Get to know the sensors and straps
1. What's in the pouch?
The sensors are inside the straps: remember how they were placed
It is important to place the sensors correctly in the straps.
2. Turning the sensors on/off
To turn on: press and hold the power button until the light turns on (white or slightly pink). ●
To turn off: press and hold the power button until the light blinks pink, then stops. ●
3. Check battery level
When the sensors are on, press the power button once and count the number of blue light blinks: it indicates the battery level.
● 1 = 0-25%● 2 = 25-50%● 3 = 50-75%● 4 = 75-100%
Red blinking indicates low battery ●
4. Charge your sensors
- Plug your sensors using the provided charger (USB-C).
- Turn sensors on.
- ● Blue light blinking - charging
- ● Blue light solid - fully charged, plugged in
- ● Other color - not plugged in
- 💡 Turn sensors off to charge faster.
Charging time: 5 hours from empty to full
Battery life: about 1 hour on ice.
5. Wear Jump Tracker on the ice
1. Place the sensors in the straps
- Place Right sensor in the Right strap aligning the button with the button slot (see image below)
- Repeat with Left sensor in Left strap
- You should see the sensor light shine through the button mark on your strap (if your strap is white)
- Close the straps and ensure sensors are securely in place.
2. Attach the straps to the skates
- The sensors go under the skates.
- The two arrows point toward you when attaching the straps to the skates.
- Straps are correctly placed if L and R are as shown on the image.
💡 If the sensors are wrongly placed, the jump call may be wrong.

Understanding your data
Air time
Air time is the amount of time you spend in the air during a jump. In figure skating, it is a direct measure of jump height—the higher you jump, the longer your air time.
Every jump requires a minimum amount of air time to complete the required rotations. Comparing your air time to the recommended minimum can help you identify whether you should focus on:
- Jumping higher to gain more time in the air.
- Rotating faster to complete the rotation within your available air time.
Accuracy: ±0.01 s or better, independently verified by IAT Leipzig.
Prefer jump height? Change the displayed metric by clicking
next to the air time of one of your jumps.
Rotation speed
Rotation speed is how quickly you rotate. For example, a fast spin has a higher rotation speed than a slow spin. The faster you rotate, the more revolutions you can complete before landing.
Jump Tracker measures how your rotation speed changes throughout the jump and displays your average rotation speed, making it easy to compare different jumps.
Displayed unit: degrees per second (°/s) in the Jump Tracker app.
Other common units: revolutions per second (rps) or revolutions per minute (rpm).
Compare your average rotation speed with the Required Rotation Speed to see whether you may need to rotate faster, jump higher to gain more air time, or both.
In-air rotation
Jump Tracker measures how much you rotate from the moment you leave the ice until the moment you land. This is called your in-air rotation.
In-air rotation is a useful measure of how much you rotate during your jump. From it, we can estimate whether your jump was clean or under-rotated—see Landing rotation.
Measured: from the moment you leave the ice until you land.
Excludes: any rotation before takeoff (pre-rotation).
Because it leaves out pre-rotation, in-air rotation also helps you track your progress toward a new jump and estimate whether you use more or less pre-rotation than typical. Jumps with high in-air rotation (often called Over) point to less pre-rotation, while jumps with low in-air rotation (often called q, <, or <<) point to more.
Minimum recommended air times
The minimum recommended air time is the air time you should aim for to consistently complete a specific jump. Each jump requires a certain amount of air time to finish the required rotation.
Based on: measurements of thousands of jumps and years of coaching experience.
Keep in mind: depending on your technique and body type, you may need slightly more than the recommendation.
Jump height
Jump Tracker measures your air time and calculates your jump height from it. For normal figure skating jumps, air time is a direct measure of jump height.
Assumes: a typical technique, where your body position at takeoff and landing is similar.
Best used for: comparing your own jumps over time.
The estimate may be less accurate if your body position changes significantly during the jump—for example, if you bend your knees just before landing—or when measuring movements that are not actual jumps.
Required rotation speed
The required rotation speed is how fast you need to rotate to land a jump clean.
The higher you jump, the more air time you have—so you can afford to rotate a little slower and still land clean, and vice versa. Given your air time, Jump Tracker calculates the rotation speed you'd need, assuming a typical amount of pre-rotation (see In-air rotation).
Depends on: your air time (jump height)—more air time lowers the speed you need.
Assumes: a typical amount of pre-rotation.
Use it as a goal: aim to reach the required rotation speed—by rotating faster, jumping higher, or both—and track your progress until you consistently reach it and land the jump clean.
Landing rotation BETA
Landing rotation is a training estimate based on your in-air rotation, assuming a typical amount of pre-rotation. It is not an official judging result and should not be used to evaluate or challenge competition calls.
Landing rotation calls:
OverOver-rotated
CleanFully rotated
qLanded on the quarter: missing exactly ¼ of a revolution
<Under-rotated: more than ¼, but less than ½ of a revolution short
<<Downgraded: ½ revolution or more short
Seeing Over often?
You may be using less pre-rotation than average, so more of your rotation happens in the air.
Seeing q < << often?
You may be using more pre-rotation than average, so less rotation happens in the air.
Problem with jump detection
A jump was detected but I did not jump
Jump Tracker is very accurate at detecting jumps. Sometimes it can still mistake another movement for a jump. If you do not want this movement in your data, you can delete it in the app.
If Jump Tracker is making a lot of mistakes, check these issues:
I keep seeing A or 1Lo between jumps
Hops and half-jump drills can look like real jumps. If you do not want them in your data, remove them with Delete.
My jump was not detected
Jump Tracker is very accurate at detecting jumps, but sometimes it can still miss one. You can add a jump to your session using the Add Jump button.
- Confirm sensors are Online during the session.
Jump Tracker is currently optimized for detecting double, triple, and quadruple jumps. We are working on a better version for single-jump detection.
The wrong jump got detected
Jump Tracker has around 91% accuracy on jump classification, but sometimes it makes mistakes. You can edit the call through the app.
Note: Rotation speed, air time, and in-air rotation remain accurate even if the jump label is wrong.
If Jump Tracker is making a lot of mistakes, check these issues:
My triple was detected as a double
Jump Tracker classifies a jump from your in-air rotation—how much you rotate while you're in the air. It doesn't measure any rotation that happens before takeoff (pre-rotation).
Because of this, Jump Tracker can't always tell apart:
- a clean double with little or no pre-rotation, and
- a downgraded (<<) triple with significant pre-rotation.
This is completely normal while learning a new jump. As you complete more of the rotation in the air, Jump Tracker will start recognizing more of your attempts as triples.
1A detected as 2Eu
This is usually caused by sensor orientation/placement. Check that R is on right foot and L on left foot, both right-side up and visible. Also verify each sensor is in the correct strap with the sensor light visible through the oval window.
Salchow detected as Axel
If your Salchow keeps getting detected as an Axel, move the sensor slightly toward the outside of the boot. This helps Jump Tracker better read your take-off pattern.
Axel detected as Salchow
If your Axel keeps getting detected as a Salchow, move the sensor slightly toward the inside of the boot. This helps Jump Tracker better distinguish the take-off direction.
My jumps are detected as NLJ
NLJ means "non-listed jump" and is used for jumps that Jump Tracker is not able to classify. If it happens a lot, it is generally caused by the left and right sensors being on the wrong side. Check that R is on the right foot and L is on the left foot, both right-side up and visible. Also verify each sensor is in the correct strap, with the sensor light visible through the oval window.

Sensors & sensor care
How to update your sensors
Updates happen automatically during regular use. After an update is released, your sensors download it during the next session and install it the next time they are turned on. This means they will normally be updated by your second session.
Want to update your sensors before your next session? Follow the steps below.
-
Turn on your phone hotspot
Turn on the hotspot your sensors already know, with internet access and Compatibility Mode enabled.
📖 Need help? Phone Hotspot Guide -
Turn on both sensors
📖 Need help? Sensor Management Guide -
Wait until both sensors blink green
Leave them on for 3 minutes.
Not blinking green?
Before you continue, quickly check:
- The hotspot is on, has internet, and Compatibility Mode is enabled.
- This is a hotspot your sensors have connected to before.
- Both sensors stayed on for the full 3 minutes.
Still not blinking green? Open the guide below:

Connection issue? See connectivity troubleshooting.
How does Jump Tracker connectivity work?
Jump Tracker sends data through your phone hotspot to our cloud for processing. Detected jumps are then securely sent back to your web app.
Aiving Connected Rink BETA
An Aiving Connected Rink is a dedicated Wi-Fi network that lets fully updated Aiving Jump Trackers connect automatically at the rink. Skaters and coaches can use Jump Tracker without relying on a phone hotspot.
How it works
An Aiving Connected Rink consists of a dedicated router connected to the rink's internet connection and configured with a Network Name (SSID) and password provided by Aiving. The router can be installed permanently or brought to the rink whenever it is needed.
Applying to become an Aiving Connected Rink is free of charge.
Costs and responsibilities
The organization (rink, club, coach, etc.) that sets up the Aiving Connected Rink is responsible for managing it. Budget approximately $60 for the router, plus any installation costs. Depending on the rink setup and available IT support, installation can cost anywhere from $0 to several hundred dollars.
Setup is straightforward for someone with basic IT knowledge. If your organization has someone with IT experience, they may be able to complete the setup without additional cost.
How to know if connectivity is good in the app?
Open the Aiving app and check the sensor status.
- Sensors show Online status.
- Data appears with low delay during session.
- Signal quality indicators remain stable.
