Coaching built on your real data.
FollowStride reads your Apple Health history — HRV, resting heart rate, sleep, pace, training load — and coaches you from it. Not a generic plan. Not made-up numbers.

How it works
Three steps to a coach that knows your data.
01
Connect Apple Health
Grant access to HRV, sleep, resting heart rate and workout history. Nothing leaves your device.
02
Get your readiness score
FollowStride reads your own baselines and tells you if today's a day to push or recover — with the reasoning shown.
03
Train with an AI coach
Ask about pace, recovery or your last run. Every answer cites the metric behind it.
The difference
It tells you when it doesn't know.

Insufficient data yet
Most training apps fill the gaps with plausible-looking numbers. If Apple Health has nothing for a metric, you get a dash — and a note on what would supply it.
Your numbers, read properly.
Daily readiness
Scored from your own HRV, resting heart rate and sleep baselines — reasoning shown, not just a number.
AI coach
Ask about training, recovery or your last run. Answers come back in your actual zones and paces.
Training load
Acute:chronic workload, so you can see a mileage ramp before it turns into an injury.
Run tracking
Route, splits, pace and elevation — recorded on iPhone or Watch, written back to Apple Health.
Injury signals
Built only from what's measurable — mileage ramp, cadence, sleep, HRV. Never a guess.
Shoe tracker
Mileage per pair against the usual retirement guideline, updated from your runs.

Ready for tomorrow's tempo?
Yes — readiness is 86, HRV trending above baseline. Keep it at Zone 3, 147–159bpm.

What it does
Every score is computed against your own history.
A 55ms HRV is excellent for one runner and a warning sign for another — only your own baseline says which. The coach names the number behind every recommendation, so you can check its work.
Your training data stays on your phone.
No trackers, at all
No analytics, advertising or attribution SDKs. Built entirely on Apple frameworks.
Your route never leaves
Coaching requests carry a metrics summary — never GPS coordinates, email or device IDs.
Nothing retained
Requests generate a reply and aren't stored. Sign out and the app erases its local data.
Train on what's actually true.
