Training that adapts
to every run.

Adaptive plans, guided runs, and coaching built around the runner you are today — from your first 5K to your first ultra.

A finished Austin Marathon in Momentum: the whole course traced in lavender across the city, 26.22 miles in 2:58:41 at 6:49 per mile.

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.

Know what to run.

Base. Build. Peak. Taper. Every session has a reason, every pace has a purpose, and missed days simply move.

Week 4 · Recovery — a planned down week

Momentum's weekly plan: a marathon block 28 weeks out, showing a planned recovery week of 32 miles with an easy run, a recovery jog, two rest days, and a progression run.

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.

A guided run in progress: the live lavender route trace, the current recovery interval, distance, pace, and heart-rate zone.

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.

Every adjustment is explained03
The Momentum coach: asked to brief today, it lays out the session step by step — a 4 mile tempo at 8:25 per mile, the warm up and cool down around it, and the Z4 heart-rate band it should sit in.
Momentum's Fuel page: 3,050 calories against a 2,100 floor, roughly 390 grams of carbs banked for tomorrow's session, macro rings for carbs, protein, fat and sodium, and meals logged in plain language.

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.

Everything else

The rest of the picture.

Training is one screen of many. What you did, what it cost you, and what your body did about it — all of it kept, all of it yours.

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.

06 · Questions

Before you start.

Is there a free trial?

Yes. momentum is a membership: every new runner starts with a 3-day free trial of momentum Pro on the annual plan, then $79.99 billed yearly, which works out to $1.54 a week, 75% off the weekly price. Prefer to go week to week? $5.99, no trial. Cancel anytime in your Apple subscriptions and you keep access until the end of the period.

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.
