VO2 max — how efficiently your body uses oxygen while running — is the single greatest predictor of how long and how well you live. VO2boost is the structured program, with a real voice coach, that actually moves that number.

The Problem
Most runners have heard of VO2 max. They've read about Zone 2 and Norwegian 4x4. But understanding the science and following a consistent program to improve it? That gap is where progress dies.
Running the same familiar route at the same comfortable pace, week after week, doesn't improve your VO2 max. It just maintains it. You need a program — and most apps don't give you one.
Most running apps log your distance and stop there. They measure your runs. They don't guide them. Knowing your pace after a run is very different from being coached through it in real time.
WHOOP: $200/yr. Runna: $120/yr. TrainingPeaks: $135/yr. The average person already spends $133/month on subscriptions. You shouldn't need another one to improve your fitness.
A structured, science-backed path to a higher VO2 max — with a real voice coach counting you through every interval, triggered by your heart rate. One-time $9.99 at launch. No subscription ever.
Key Features
Your personal coach guides every run. Live heart rate zone feedback, pacing cues, and interval prompts keep you in the optimal zone — triggered by your actual HR, not a timer.
When your heart rate crosses a zone boundary, your coach responds immediately. Push too hard in Zone 4? You'll hear it. Drop too low in Zone 2? You'll hear that too.
Optimal cadence (170–180 SPM) reduces injury risk and metabolic cost. VO2boost's metronome runs alongside your voice coach — no second app, no second screen.
Watch your VO2 max climb with clear analytics that connect your training to real health outcomes — cardiovascular age, healthspan trajectory, and weekly progress.
Not generic interval workouts. The exact methods published in peer-reviewed research and used by elite endurance coaches worldwide — fully explained and coached.
Complete access to every protocol, every coaching session, every analytics tool — for a single one-time payment. No subscription. No renewal. No regret.
Training Protocols
Named after the researchers who proved them. Coached by a real voice that keeps you honest on every interval.
The gold standard for maximum VO2 max adaptation. 4 × 4 min at 90–95% HRmax with 3-min active recovery.
Alternating 30-second bursts at VO2max and 30-second recovery. High reward, manageable fatigue.
High-density intervals for lactate threshold and VO2 ceiling. 13 reps of 30s work / 15s rest.

Early Feedback
"Finally an app that actually talks me through Norwegian 4x4. The voice coach calling out my HR zones mid-interval is a game changer. I don't have to look at my watch at all."
"I cancelled Strava the week I installed this. VO2boost does what Strava promised to do — actually coaching me, not just measuring me."
"The built-in metronome running alongside the voice coach is the detail I didn't know I needed. My cadence went from 155 to 172 SPM in two weeks without even thinking about it."
