No, you can use SmartRope as a stand-alone device that counts your jumps. However, the robust functionality offered by the Smart Gym mobile platform is fundamental to the SmartRope experience.
SmartRope has been specially designed to withstand shock and impact during rigorous exercise, while remaining flexible and lightweight for ideal jump rope. SmartRope has been tested to withstand continuous use during hundreds of thousands of jumps, with a load rating of 20 kg (44 pounds) – more than double the strength of a traditional jump rope.
SmartRope is protected by a 60 day, repair or replace warranty that covers any issues arising from normal usage. Proof of purchase is required.
Due to all the tech housed inside SmartRope, the rope length cannot be adjusted. We offer SmartRope in five lengths to accommodate most jumpers.
If you’re in between sizes, generally speaking shorter ropes are faster and longer ropes are slower. If you’re experienced with the jump rope, you may want to size down; if you’re a beginner, sizing up may prove easier.

At launch, SmartRope displays the numbers of jumps you’ve completed as you work out. In future software updates, SmartRope will display numbers based on the mode you’re using in the Smart Gym mobile app – calories burned, interval training data, and so on.
Each jumper is a different height and has a different jumping stance, so it’s important to find the right angle for the LED display. To adjust this, simply rotate the left-hand handle (the handle with the power button) in your palm slightly to bring the display higher or lower.
Yes, there are brightness settings accessible in the device settings menu of the Smart Gym mobile app (top right hand corner of the main screen, tap the jump rope icon).
The power button (at the bottom of the left-hand handle) controls SmartRope. Lifting open the rubber cap reveals the micro-USB charging port. This power button glows different colors to indicate the status of SmartRope:
Blue LED (fast pulse) – Searching for smartphone via Bluetooth
Blue LED (slow pulse) – Paired with smartphone via Bluetooth
White LED (slow pulse) – Standby mode
Red LED – Less than 20% battery remaining, charging mode
Green LED – Fully charged
SmartRope is specifically designed to be ergonomic and provide a comfortable grip while you’re working out. The handles are sweat-resistant and slippage shouldn’t be an issue during intense workouts. If you want some extra grip or protection for your SmartRope, silicon Soft Grips are available in a variety of colors.
Unfortunately, most of the heart rate monitoring technology featured in fitness products face significant accuracy issues. In most major studies, all of the wearables on the market today do not accurately track heart rate. In fact, most wearables can’t even track heart rate during activity – only at rest, which isn’t very useful for a jump rope.
Due to all the technology packed into each SmartRope, each unit needs to be a single integrated design. A flexible printed circuit board powers 23 LEDs that are embedded into the rope itself, connected to magnetic sensors that operate on ball bearings in the handle. This is all connected to the CPU and Bluetooth transmitter, also embedded in the handle.
To ensure quality production, the current inventory of SmartRope is made wholly in Korea, using existing Tangram vendors.
SmartRope can be delivered to any country that isn’t restricted by US regulations. International shipping will be dynamically priced based on actual costs from our shipping providers (Fedex, UPS). Due to different regulations in each market, we cannot be held responsible for any customs or duties charges incurred in shipment.
SmartRope is powered by a high-quality lithium polymer battery, charged via micro-USB cable (the same cable that charges most smartphones, as well as other portable devices). Charge SmartRope with your smartphone charger, or plug it into any powered USB port on your computer. Since most SmartRope users will have access to micro-USB cables, this cable will not be included with SmartRope to reduce packaging and shipping costs.
SmartRope’s battery lasts for approximately 48 hours, or over 2 weeks of regular use. SmartRope full charges in 2 hours over a standard smartphone charger or powered USB port.
SmartRope is available in three handle colors: Chrome, Black, and Gold. To customize your rope and protect it from wear and tear, we also offer silicon Soft Grips in a variety of colors: Blue, Orange, Green, Pink, and Neutral (semi-transparent).
The LED display is only available in bright white. LEDs that display multiple colors require a thicker CPU to control each light, which would make the rope too thick to use as a good jump rope. We’ve incorporated high-quality, bright white LEDs that provide clear visibility in bright environments.
Yes! The magnetic sensors used in SmartRope track both the completion of each revolution (registering one complete jump) and the speed of the revolution (RPM). We’re working on a future firmware release that will display a successful double under on the LED display, as well as track it in your workout via the Smart Gym mobile app.
Tricks that involve full rotations of the rope also register as jumps and are tracked by Smart Gym, although the rope needs to be in normal use to display the number in mid-air.
Smart Gym will be available for free download on the Apple App Store for iOS and Google Play for Android. Specific apps for Apple Watch and Pebble Watch are also in development and will be available for free download on their respective stores.
Yes, Smart Gym will pair to different SmartRopes. However, due to the limitations of Bluetooth, only one SmartRope can be paired at a time.
You will be notified of new versions of SmartRope’s firmware via pop-up messages in Smart Gym. Go to Device Settings > Firmware, and a red ‘N’ should appear next to outdated firmware. Click on the ‘N’ to install the new firmware.
