THE EXPERIENCE
YOUR COACH.
IN YOUR
EARS.

STRNG doesn't show you a video. It talks to you — mid-set, during rest, between reps. Like a real PT, it adapts to how you're actually performing.

Works with any headphones — AirPods, Bose, Sony, wired
Responds to your natural voice — no tapping, no typing
Remembers every session — your history, PRs, and struggles

WHAT STRNG DOES
BUILT FOR
REAL TRAINING.
🎙
VOICE-FIRST COACHING
Your phone stays in your bag. STRNG coaches you entirely through your headphones — tracking your reps, adapting your session, and motivating you based on exactly what you say.
CORE FEATURE
🧠
ADAPTIVE AI
STRNG tracks every rep. Stronger today? It increases the weight. Struggling? It adjusts instantly. Every session is built around your actual performance, not a generic plan.
REAL-TIME
⚡
SMART TIMERS
No buzzers. Coach brings you back when your body is ready — using heart rate data and performance signals to time your rest perfectly.

GYM-ADAPTIVE PROGRAMS
Tell STRNG what equipment you have today — full gym, hotel weights, or just bodyweight — and it builds the perfect session around reality, not assumption. Every location, always optimal.
ALWAYS READY
⌚
APPLE WATCH + HEALTHKIT
Live heart rate, HRV recovery scores, and sleep data feed directly into STRNG's decision-making. Coach knows when to push and when to hold back — before you even step in the gym.

THE PROCESS
FOUR STEPS TO
A STRONGER YOU.
01🎙
TELL COACH WHO YOU ARE
A 5-minute voice conversation. Training history, goals, injuries, available equipment. No forms — just a conversation.
02📋
GET YOUR PROGRAM
STRNG builds a periodized plan around your life — schedule, equipment, and goals. Negotiated with you, not handed to you.
03🎧
PUT IN YOUR HEADPHONES
Tap Start. Coach is live. Phone in pocket, any headphones on, and you're being coached in real time.
04📈
WATCH YOURSELF GROW
Every session STRNG learns more about your body. The coaching sharpens. The results become real.
🏆
PR DETECTION
STRNG recognises personal records in real time — celebrates them with you, then explains exactly how you got there.
👻
GHOST MODE
Race against your past self. Coach narrates live whether you're ahead or behind your best-ever session.
😮
FATIGUE DETECTION
Dropped reps? Spiking RPE? STRNG catches it before you do and adjusts session volume automatically.
COACH IS SPEAKING
"205 pounds. That's a new PR. You've added 20 lbs to your bench in 6 weeks — that's what consistent training looks like."

Poor sleep? High stress? STRNG adjusts your session before you start, protecting you from overtraining automatically.

EARLY FEEDBACK
WHAT ATHLETES
ARE SAYING.
"I've tried every fitness app. This is the first one where I actually felt like someone was with me. I pushed harder on every set because I didn't want to let Coach down."

"I'm a runner trying strength training for the first time. Mentor mode explained every exercise while I did it. I went from terrified of free weights to owning them in 3 weeks."

"The pre-session check-in changed everything. On days I said I was tired, Coach adjusted the whole session before I touched a weight. That's exactly what a real trainer does."
