It has read every ride you've recorded — every watt, every climb, every battery curve — because the numbers never left your phone. The app is the instrument. The Wrench is the mind behind it, and it never phones home: all inference runs on your iPhone and your Mac.
Every byte the app stores is the Wrench's workspace — rides, telemetry, battery history, components, goals, terrain. When a new kind of data ships, the Wrench reads it automatically. That's enforced in the code, not promised in the copy.
You shouldn't have to ask. The Wrench forms observations — patterns you can't see — and surfaces them where you already are, each one citing the rides behind it. "Tell me what you know" is a screen, not a chat box.
The same intelligence looks through a different lens on every screen: the garage, the trailhead, the ride record, the edit bay. The mechanic's wear model informs the coach; terrain informs both.
Knows your goals and — if you allow it — your recovery: sleep and resting heart rate, read from Apple Health on the phone and never uploaded, in any mode, ever. It tells you which goals are at risk and what your own history says helps.
Tracks the parts on your bike and accrues their usage from the bike's own odometer once a baseline exists — measured miles, weighted by the terrain you actually rode, because a rocky descent kilometre is not a fire-road kilometre to a brake pad. Service suggestions arrive with the evidence attached, never a diagnosis dressed as fact.
Fingerprints every ride's terrain from measured samples — climb load, technicality, descent exposure — and shows you what technical ground actually costs you, so you plan battery by terrain, not distance.
In the Mac Studio, hand the edit over: tell it "60-second social cut, clean frames" and it stages a plan with a measured reason per cut, then leaves you an ordinary editable timeline. Handover, never lockout.
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
97% of the 620 mi window · a rocky-descent mile is not a fire-road mile
Usable capacity steady across 41 measured rides.
The Mechanic. Parts accrue measured, terrain-weighted usage — 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 OpenLevo does today keeps working without the Wrench. Safety features are never paywalled. Your data and its export are yours.
No account. No cloud. No rider-data server exists — there is nothing to breach, subpoena, or quietly monetize. The workspace, the observations, and the inference all live on your devices. That isn't a settings toggle; it's the architecture.
The Wrench will ship as one App Store subscription across iPhone, Apple Watch, and the Mac Studio. 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.
