It has read every ride you've recorded — every watt, every climb, every battery curve — because the numbers are on your phone. The app is the instrument. The Wrench is the mind behind it, and it works where your rides are: on your iPhone.
Knows your goals and, if you allow it, your sleep and resting heart rate from Apple Health, and tells you which goals are at risk.
Tracks the parts on your bike against the bike's own odometer and suggests service with the evidence attached.
Shows what technical ground costs you in battery, so you plan by terrain, not distance.
Stages a first cut of your ride film with a reason for each cut, then hands you an ordinary editable timeline.
Tuesday rides average 11.2 Wh/mi against your overall 13.6 Wh/mi — 18% less energy per distance.
Woven in, cited always. The perspective card thinks out loud atop Performance — every claim carries the interpreted chip and the rides behind it.
The Ledger. Durable, dated, honest — confirmations strengthen, and when the data turns, the retraction shows instead of disappearing.
1,840 Wh battery used this month · 12 rides · −9% vs the previous month
14.9 mph average this month · +6% vs the previous month
Ask. Questions compile to the same analytics the charts use. Name nothing measurable and it says so — it never guesses.
45% of the 930 mi window
83% of the 620 mi window
Usable capacity steady across 41 measured rides.
The Mechanic. Parts track measured miles; suggestions arrive with the evidence, never a diagnosis dressed as fact.
The Wrench advises. It has no authority over your bike's settings, and never will.
Every claim is marked interpreted and cites the rides behind it. Below the evidence threshold it says nothing — and when the data stops supporting a claim, the retraction is shown, not hidden.
Messages, exports, shares — a human taps the button. Always.
Everything Action Studio Pro does today keeps working without the Wrench. Safety features are never paywalled. Your data and its export are yours.
The workspace, the observations, and the inference live on your devices, and nothing leaves them unless you choose to share it.
The Wrench will ship as one App Store subscription across iPhone and Apple Watch. We're setting its price with riders, not for them — the waitlist gets the first say. Joining is an email address and nothing more: no account is created, nothing is tracked.
