Jumpable™
Improve your vertical with Jumpable™
Meet the app that brings accurate jump metrics to your Apple Watch.
Level up in one move
Strap the Apple Watch to your ankle and you're set.
Take flight in seconds
Strap
Make sure the Apple Watch is snugly secured to your inner ankle for best results.
Tap
Select a recording duration, tap play to begin recording, and start your jump session.
Recap
Instantly review results measured by our advanced algorithms, track your progress, and optimize your training.
Reach new heights with accuracy
Jumpable™ brings you everything you need to measure, manage, and improve your vertical jump.
Number of Jumps
Automatically detects countermovement and squat jumps performed and displays the metrics for your best jump.
Jump Height (cm or in) & Flight Time (ms)
Tests your explosive capability and marks performance recovery. It directly translates to dunks, spikes, and blocking shots.
Peak Power (W/kg)
Captures your power output relative to bodyweight at takeoff. It indicates how efficiently your strength converts to explosive movement.
Peak Velocity (m/s)
Measures the speed at which you leave the ground. It directly translates to performance in sprinting, cutting ability, and reactive strength.
Peak Force (N/kg)
Highlights your maximum ground reaction force generated at takeoff. It reveals how strong you are for your bodyweight.
Left vs. Right Asymmetry
Tests your one-legged jump performance. It identifies and addresses hidden weaknesses that limit your performance.
Return to your peak with confidence
Jumpable™ helps you get back to your sport safely by providing the objective evidence needed to optimize recovery. As sports physiotherapists say – rehab without data is just expensive guesswork.
Pre-injury Baseline
Find out what your 100% looks like.
Recovery Milestones
Measure your progress with data.
Load Progression
Add intensity at the right time.
Return-to-Sport Confidence
Step back on the field with evidence.
Reduced Re-injury Risk
Catch performance drops before they
become a risk of re-injury.
Take off with precision

We do not collect any personal information that can identify you. The App does not require account creation, email addresses, names, or any other personally identifiable information.2.2 Motion Sensor Data
The App collects anonymized motion sensor data from your Apple Watch, including:
• Accelerometer and Gyroscope readings during jump measurements
• Timestamp information for data processingImportant: This motion sensor data is:
✓ Completely anonymized and cannot be linked to your identity
✓ Used solely to improve our measurement algorithms
✓ Processed in aggregate with other users' data
✓ Never combined with any identifying information2.3 Data We Do NOT Collect
We do not collect, access, or store:
• Personal identifying information (name, email, phone number)
• Location data or GPS coordinates
• Health records or medical information
• Contact lists or device identifiers
• Browsing history or app usage patterns
• Any data that could identify you personally3. How We Use Information
3.1 Algorithm Improvement
The anonymized motion sensor data is used exclusively to:
• Improve the accuracy of our jump measurement calculations
• Enhance the performance of our biomechanical algorithms
• Validate and refine our motion analysis techniques
• Develop better measurement methodologies3.2 What We Don't Do
We do not:
• Track individual users or create user profiles
• Sell, rent, or share data with third parties for marketing
• Use data for advertising or commercial purposes beyond app improvement
• Combine motion data with any identifying information
• Create behavioral profiles or user analytics4. Data Storage and Security
4.1 On-Device Processing
All jump measurements and personal performance data remain on your Apple Watch and iPhone. We do not store your individual jump results, performance metrics, or personal training data on our servers.4.2 Anonymized Data Security
The limited anonymized motion sensor data we collect is:
• Encrypted during transmission and storage
• Stored on secure servers with industry-standard protections
• Accessible only to authorized personnel for algorithm development
• Retained only as long as necessary for improvement purposes
• Automatically aggregated to prevent any potential identification4.3 Data Retention
• Your personal jump data: Stored only on your devices, under your control
• Anonymized motion patterns: Retained for algorithm improvement, typically 2-3 years
• Aggregate data: May be retained longer for ongoing research and development5. Your Rights and Choices
5.1 Control Over Your Data
• All your personal jump measurements remain on your devices
• You can delete the App and all associated data at any time
• No account deletion needed since no accounts are created5.2 Opting Out
Since we only collect anonymized, non-identifying motion patterns, there are no personal data collection settings to modify. If you prefer not to contribute any data to algorithm improvement, you can contact us to discuss technical alternatives.5.3 Data Portability
Your jump measurements and performance data are stored locally on your devices and can be exported through standard Apple sharing mechanisms.6. Third-Party Services
