Jab Counter Support
Frequently Asked Questions & Contact
Can Apple Watch track boxing punches?
Yes. Jab Counter uses the accelerometer built into every Apple Watch to detect and count lead-hand punches. No additional sensors or hardware are required.
Which Apple Watch models are compatible?
Jab Counter requires watchOS 26 or later. Any Apple Watch that supports watchOS 26 is compatible.
Which wrist should I wear my Apple Watch on?
Wear your Apple Watch on your lead hand wrist. For orthodox fighters that is the left wrist; for southpaw fighters the right. Because Jab Counter tracks the lead hand specifically, wearing it on the wrong wrist will result in inaccurate punch counts.
Is Jab Counter really free?
Yes. As of version 2.1, every feature is free for everyone: punch counting, G-force measurement, heart rate, calories, Apple Health sync, workout history, monthly stats, workout sharing, the round timer, Training Trends, Punch Dynamics, and AI Punch Classification. There is no purchase, subscription, or trial required.
Is there a Pro version or paid upgrade?
No. Jab Counter Pro has been discontinued and everything it used to unlock, including Training Trends, Punch Dynamics, and AI Punch Classification, is now free for everyone.
What punches does Jab Counter count?
Jab Counter tracks all lead-hand strikes. An on-device AI model (Beta) also identifies punch types in real time: jabs, hooks, and uppercuts, with a color-coded breakdown after every session.
How accurate is the AI punch classification?
Punch classification is a Beta feature and, like any machine learning model, it is not perfect. Some punches may be misclassified, particularly in fast combinations or when technique varies. We are actively improving the model and accuracy will increase with future updates.
Does it work for heavy bag, shadowboxing, and pad work?
Yes. The app tracks your lead-hand output across all three. Start a session, begin training, and Jab Counter logs the full session automatically.
Can I use Jab Counter for Muay Thai, Kickboxing, or MMA?
Muay Thai and kickboxing work well. Both sports involve lead-hand punching on the bag and pads, and Jab Counter will track your punch volume, power, and acceleration accurately. Kicks and elbows are not tracked. For MMA it depends on your training. Striking-focused rounds will give you useful data, but grappling and clinch work may introduce some noise into your stats.
Does Jab Counter work without an internet connection?
Yes. Jab Counter works entirely on-device. Workouts are tracked on your Apple Watch with no internet connection required. Data syncs to your iPhone via Bluetooth when in range, and to Apple Health automatically. Nothing is sent to external servers.
Does Jab Counter sync with Apple Health?
Yes. All session data including punch count, heart rate, calories, and duration syncs automatically to Apple Health via HealthKit.
Why won't Jab Counter show my workouts or start on my Apple Watch?
This is almost always caused by missing HealthKit permissions. On your iPhone, go to Settings > Privacy & Security > Health > Jab Counter and make sure all permissions are turned on. Once granted, restart the app on your Apple Watch and try again.
Is there anything that can affect accuracy?
Punch detection uses wrist accelerometer data. High-energy activities like jump rope may register as light punches. You can exclude specific intervals (warmups, jump rope, cooldowns) directly in the app to keep your punch stats accurate.
