Quick Start
Open app. Start jumping
Stop guessing which workout to start.
Your goal. Your pace. And course.
RAYNOLSE asks a few simple questions, then builds a guided session around you.
Jump naturally. We’ll read the rest.
Your first free jump becomes your baseline.
RAYNOLSE tracks your pace, rhythm, rests, and fatigue points, then uses them to build your course.
What RAYNOLSE reads while you jump
PACE
RAYNOLSE measures your real jumping speed from successful jumps and active time. It turns that into live RPM, average pace, and peak pace, so your course starts from the speed you can actually hold.
RHYTHM
RAYNOLSE follows how your RPM changes throughout the session. It sees whether your tempo stays steady, starts drifting, or breaks at certain points.
REST
RAYNOLSE separates actual jumping time from pauses and rest moments. That means your workout is built on real effort, not just the total time on the clock.
FATIGUE
RAYNOLSE looks for the points where your pace drops, misses increase, or rest gets longer. Those signals help the app understand when your body starts to fade and how hard today’s course should be.
No more “1,000 jumps.” Follow your course.
Built from your baseline.
RAYNOLSE reads how fast you jump, where you miss, when you rest, how long you last, and what you are training for.
Then it builds a course that pushes you just enough, changes pace before it gets boring, and tells you what to do when your rhythm starts to fall.
Your baseline turns into today’s workout.
Train your way. Still get coached.
Free. Count. Boxer.
For interval training, Boxer Course turns your rope into more than a timer.
Watch your RPM live, feel key cues through vibration, and keep every round inside the right pace.
Progress is more than a number.
RAYNOLSE helps you build the habit.
See how often you train, when you usually work out, how your pace changes, and how consistent you are becoming.
Because the goal is not just one good session. It is coming back tomorrow.
All the coaching starts in the handle.
RAYNOLSE is not just an app timer. The handle tracks your pace and workout flow, the app turns it into a course, and vibration cues help you follow it while you jump.
Engineered for steady rotation.
Dual bearings inside. Smooth rhythm outside. A dual-bearing handle helps the rope spin smoothly, stay stable at pace, and feel consistent through everyday cardio sessions.
Aluminum body. Confident hold.
The aluminum grip gives RAYNOLSE a solid feel in your hand, so it feels like training gear you can use every day.
Connected handle.
Guided app.
One workout system.
The new era of jump rope starts with RAYNOLSE.
