How it compares
While standard digital ropes rely on handle-based screens, the Tangram Factory Smart Rope LED literally projects your jump count in the air in front of you. Compared to standard weighted cables, this is a speed-focused rope with a slightly higher weight profile due to the embedded LEDs. It offers a more immersive experience than basic smart ropes, though it requires a specific jumping arc to ensure the LEDs are visible to the user.
How to use it
- Charge the rope fully using the micro-USB port located in the handle.
- Power on the LEDs and sync the rope with the SmartRope app via your mobile device.
- Hold the alloy handles at a 45-degree angle to the floor for optimal projection.
- Start jumping; the LEDs will flash at precise intervals to create a numeric display in your line of sight.
- Monitor your progress and unlock awards through the app's competitive community.

Sustainability & ethics
Tangram Factory emphasizes longevity through rechargeable technology, eliminating the need for disposable batteries. The rope is 100% vegan, utilizing polycarbonate and alloy materials. They use FSC Certified materials for their product documentation and box inserts to ensure responsible forestry practices.
Pro tip
Ensure you are jumping in a space that allows you to look straight ahead; the projection works best against a dark or neutral background.
