What's your Strike Force?
Know if you're actually getting better.
Every fighter trains hard. Most spend months repeating the same mistakes — because no one's there to catch them. Record a round on your iPhone and Coach Chip, your AI cornerman, breaks down your technique: what improved, what's slipping, and the exact fix for next session. Add an Apple Watch to measure the force behind every punch.
An Apple Watch is needed only for force and speed — form coaching works from your phone.
- Spots your hands dropping
- Catches lazy footwork
- Flags the counters you're leaving open
- Tells you how to fix each one
This week
Snap the jab back to your cheek.
The Coaching
Your corner. In your pocket.
Record a round — bag work, shadow boxing, fight footage — and Coach Chip breaks it down the way a cornerman does between rounds.
The Corner
That cross is landing with real snap — your hips are doing the work, not just your arm.
Your base is balanced and your chin is tucked, so you're covered while you punch.
Your lead hand drifts down after the jab, and that open lane is exactly where a counter comes back.
This Week
Snap the jab straight back to your cheek.
The Replay
Every callout is pinned to a moment in your clip. Tap it and the replay jumps straight there.
Clean hip turn on the cross
Power comes from the rotation, not the shoulder
Lead hand drops on the jab return
Leaves the counter lane open — return to the cheek every time
This is a real Coach Chip read. No Apple Watch needed — just your phone.

Giving back
More than an app.
Body & Boxing is a New York City nonprofit that helps young people grow through the discipline of boxing, hands-on technology skills, and character development.
In the gym and the classroom, they pair athletic training with real-world tech skills — from coding to app development — building the confidence, focus, and resilience that carry far beyond the ring.
Strike Force is a boxing app built with technology; Body & Boxing teaches the next generation of fighters to build it. That's why a portion of every Strike Force subscription supports their programs.
Why trust it
Made by a fighter, for fighters. I built Strike Force to better understand how my form and conditioning translated into real power. I knew my Apple Watch possessed the capability to capture this data — I just needed to make it happen. Now I can measure and track my power and speed anywhere I am in the world, without the need for additional equipment beyond my Apple Watch.

Answers
Frequently Asked Questions
Do I need an Apple Watch?
No. Coach Chip's camera form coaching works with just your iPhone — record or upload a round and get a full coaching report. An Apple Watch is required only for measured metrics: punch force, speed, and count.
What does Coach Chip actually tell me?
Coach Chip is Strike Force's AI coach. From a phone-recorded clip he delivers a corner read — specific praise, the one danger in your form, and one instruction for the week — plus a tappable replay that jumps to the exact moments he calls out. With an Apple Watch, his coaching is fused with your real force and speed numbers.
Which fighting styles does Strike Force coach?
Boxing, Muay Thai, kickboxing, Karate, Taekwondo, and MMA — Coach Chip coaches in your discipline's own language. You can also set a lens for the analysis: your own form, competition prep, scouting an opponent, or studying a pro.
How much does it cost?
Strike Force Premium is $2.99/month with a 7-day free trial, and your first session is free. That's about a third of what comparable coaching apps charge.
Is Strike Force accurate?
For measured metrics, Strike Force uses the Apple Watch's accelerometer and gyroscope to capture the motion of each punch and calculate G‑force in real time, paired with proprietary motion algorithms for consistent, training‑grade feedback. Coach Chip's form coaching is automated analysis of your video — training guidance, not medical or professional advice.
More questions
What is Strike Force?
Strike Force is your AI striking coach. Record a round with your iPhone and Coach Chip breaks down your technique like a cornerman — what's working, what to fix, and the exact moments in your clip that matter. Add an Apple Watch and Strike Force also measures punch force, speed, and frequency in real time.
Is Strike Force available for Android?
No — Strike Force is currently available only on iOS and watchOS. The app was designed specifically for Apple devices, as our research showed that these platforms provided the precision and sensor access needed to measure the accelerometer forces required by Strike Force. While some Android devices may offer similar capabilities, we have no immediate plans to develop an Android version at this time.
Which modes are included?
Power, Speed, Workout, and Fight—each tuned to a different goal: max force, fast hands, session endurance, or head‑to‑head total output.
Can I challenge friends?
Absolutely. Send challenges, accept or decline, and see winners with detailed results. Friends‑only leaderboards make it even more fun.
Does it work for both orthodox and southpaw?
Yes—wear your Apple Watch on your striking hand and keep it consistent across sessions.
Does it integrate with Apple Health?
Yes. Sessions can write relevant data to Apple Health with your permission.
Is my data private?
Yes. Your data is stored securely with Apple's iCloud and processed in line with GDPR/CCPA practices.
Which devices are supported?
Strike Force supports modern Apple Watch and iPhone models running current OS versions. See our App Store page for specifics.
