momentum is a coach, not a feed. It learns your body, reshapes your week around your recovery, and tells you the truth about your goal.
01 · Training
A plan that moves when you do.
Momentum starts from your actual running history, then reshapes the week as your fitness, recovery, and life change.
Run with guidance.
Pace bands, rep countdowns, heart-rate zones, and voice cues are there when you want them, then get out of the way.

02 · Intelligence
Your training knows the answer.
AI explains. The training engine decides. Momentum keeps your plan grounded in actual running data instead of inventing numbers.
A coach that learns your running.
Ask what to run, how you’re progressing, whether a goal is realistic, or why today’s session changed. Every answer starts from your plan and your history.
Plans adapt after every run01
Recovery changes tomorrow02
Every adjustment is explained03
03 · Fuel
Fuel the work. Never a diet.
Floors, not ceilings: enough carbs banked for tomorrow’s session, enough sodium for the heat, logged in plain language. Describe the meal in your own words and momentum does the numbers.
04 · The method
No red days. Only momentum.
01
Missed sessions move.
Life happens. The week reshapes itself instead of turning a missed run into failure. There is no red 'failed' state anywhere in the product.
02
Numbers you can trust.
Paces, load, and zones come from bounded, tested training logic. AI narrates the why; it never computes your numbers.
03
Your training stays yours.
Private by default, on your device first. No feeds, no kudos economy, no public-performance pressure required to make progress.
Race day
Bring a goal. momentum builds the road there.
Honest verdicts on what you can run today, projections that sharpen as you train, and a taper that delivers you to the start line ready.

06 · Questions
Before you start.
Is momentum free?
Tracking every run is free, forever. momentum Pro — the full adaptive plan, AI coach, voice guidance, and advanced analytics — is $59.99/year, which works out to under $5 a month, half the monthly price. Prefer month to month? $9.99.
Do I need an Apple Watch or heart-rate strap?
No. Your iPhone handles GPS, pace, and guided workouts on its own. If you wear an Apple Watch, a Garmin, or a Bluetooth chest strap, momentum picks up live heart rate and zones automatically — no pairing flow, no exports.
I've never run before. Is this for me?
Especially for you. momentum starts from your actual starting point — run/walk intervals if that's where you are — and its honesty engine will tell you if a goal is too aggressive rather than setting you up to fail.
How is momentum different from other running apps?
The plan adapts after every run, protectively. Recovery signals, workload guardrails, and an injury-aware loop reshape your week within tested bounds — and the coach explains every change in plain language. AI narrates; it never invents your numbers.
What happens to my data?
Your runs live on your device first — every GPS point is saved as it happens, so nothing is ever lost. Health data stays in Apple Health under your control. Your map and history are private by default, and we never sell personal data. See our Privacy Policy for the full picture.
What if I miss a workout?
It moves. momentum reschedules it with a one-line explanation, and your streak survives — rest days count and one slipped day is forgiven. There is no red 'failed' state anywhere in the product.
