Tells you what to do. Watches you do it.
A kettlebell coach on your phone. It builds your training and shows your progress. Put the sensor on the bell and it sees the reps you actually do: speed, fatigue, and how close you are to failure.
How far the
coach can see.
Start with your phone. Add the bell sensor when you want the coach to see your real output.
The app coaches you
Structured kettlebell programs, the right moves in the right order, and progression that tells you when to add weight. Works with your phone alone.
It sees your real reps
Clip the sensor under the handle and the coach stops taking your word for it. It counts the reps you really did and shows your speed holding or fading through the set, measured on the bell instead of your wrist.
The AI coach adapts
Next, the coach reads your performance and recovery and adjusts the training to match the day. In development now.
Most sessions
are a guess.
You like the kettlebell, but you're winging it. Random sessions, no real plan, and no way to tell if any of it is working.
No real plan
You show up and improvise. Some days are hard, some are easy, and none of them build on the last.
No idea when to progress
Add weight? Swap the exercise? Back off for a week? You're guessing, because nothing is keeping score.
No proof it's working
Feeling tired is not the same as getting better. Without a number, last month and this month look the same.
Pick a program.
Start training.
BellSense lays out every session. Start with your phone, then add the sensor when you want the coach to see the reps you actually do.
Pick a program
Choose a program and BellSense lays out every session. Just your phone to start.
Add the sensor
Clip the sensor under the bell handle and connect over Bluetooth. Now the coach sees the reps you actually do.
Train and progress
It counts your reps and tracks speed and fatigue, then tells you what to do next.
One score for the
whole session.
BellScore rolls speed, power and consistency into one number. The coach uses it to decide what comes next, and it moves with your training, so you can see whether a session was real work or just volume.
- Speed, power and consistency in one read
- Your first tracked session sets the baseline
- It tracks real progress, not streaks or badges

On the bell,
not your wrist.
A wrist wearable measures your whole body, a little of everything. BellSense sits on the kettlebell and measures the lift itself: the reps, the speed, and the fatigue in the set.
Tracks your day. Steps, heart rate, sleep. It notices that you worked out.
Coaches the lift. Reps, speed and fatigue, read off the bell, used to tell you what to do next.
A training tool, not a medical device. Built to make you better and show the trend.
Built for people who
want to train well.
If you want to train the kettlebell well and actually know it's working, this is for you.
You own a bell and want a plan
You've got a kettlebell and you're tired of guessing. You want a coach to tell you what to do with it.
You're new to the kettlebell
You're drawn to it, but the internet is noise. You want a clear path from wherever you're starting.
You want proof it's working
Feeling tired isn't the goal. You want to watch your reps get faster and your weight go up.
Not a do-everything wearable
You don't want one more watch that measures running, lifting and sleep, all of it roughly. You want the kettlebell done right.
Make every rep matter.
One sensor and the full BellSense app for life. The coaching gets sharper the more you train.
