## What is Apex Lines?

APEX LINES — THE PADDOCK NOTEBOOK THAT KNOWS THE TRACK

Your track days live here: sessions, cold and hot tire pressures, gearing, weather, lap times, and prep checklists — logged against real maps of 38 circuits with every corner numbered.

Riders already keep this notebook — on paper, on tape, on a laminated sheet in the pit box. Apex Lines is that notebook with the track built in.

KEEP THE RECORD
• Log every track day: sessions, laps, tires, gearing, setup. Weather fills itself in.
• Cold and hot pressures per wheel — every number you'd otherwise scribble on tape.
• Lap times with delta-to-best and personal-best flags.
• Corner notes: pin a note to any corner — line, gear, reference points. Walk the track with your coach and mark what matters to you.
• Circuit setup memory: "LAST TIME HERE — F 30.0 → 33.5." Your own numbers, from this track, recalled when you come back — and keyed to conditions, so you can see what you ran the last time it was this cold.
• Hot-pressure intelligence: cold-to-hot deltas surfaced per wheel at 0.5-psi steps, seeded from your own history.

KNOW THE TRACK
• Real maps of 38 circuits — real geometry, every corner numbered, offline in your pocket at the paddock.
• A computed reference line — minimum-curvature over the mapped pavement, contained on the asphalt by construction. A starting point to study, not "the" line: adapt it to conditions, traffic, and your event's rules.
• Corner guides that call brake, turn-in, apex, and exit — study material, not rider coaching.
• 3D circuits and a fly-the-line camera with tunable simulation: grip, braking, drive, top speed. Physics-simulation estimates, not measured data — it never claims to be your lap.

RUN THE DAY
• Prep checklists with per-category progress — the laminated sheet, digitized. Add your own items; they carry forward day to day.
• Duplicate Last Day carries your whole setup to the next event.
• RaceBox lap import with staged review — and an import preview, so you see what's in your files before you're asked to pay.
• Season stats: days, laps, circuits. Real numbers — no streaks, no projections.
• Your data is yours: single-day CSV and JSON export free for everyone; season-wide exports with Pro.

THE GARAGE
• A maintenance ledger keyed to your logged track time — log the day, and oil hours, pad life, and tire heat cycles accrue on their own.
• Your bike, your intervals: nickname is the only required field, and every component is optional. Track what you care about; the rest renders nothing.
• Seeded intervals cite their source — you accept or edit each number, and your figure is never overwritten.
• Facts, not verdicts: the ledger shows hours against your own mark. It never nags, and nothing turns red.
• Tire sets follow the tire — swap wheels and the heat cycles ride along.
• Resale-ready export: the full ledger with sources, free for every bike.
• One bike's complete ledger is free for good; Pro adds more bikes.

NOT A LAP TIMER
Apex Lines doesn't time your laps. It's the study-and-logging half of your track day — the study tool your lap timer is missing.

FREE AND PRO
Free keeps the full 38-circuit library, 2D maps with the reference line, and your first track day — never deleted, never locked. Pro opens the rest of the toolbox: 3D circuits and the fly-the-line camera, corner guides, and unlimited track days.

OFFLINE-FIRST, NO ACCOUNT
Everything works without a signal — pit lane included. No sign-up, no tracking. One app on iPhone and Mac.

## Version history (last 5 releases)

### 1.5.1 — 2026-08-25

Fresh section icons across the app — a matched set for Library, Track Day, Notebook, and the Garage.

The app now wears the same type as apexlines.app — Space Grotesk headlines, JetBrains Mono for lap times and readings.

Fixed a first-launch crash when running the iPhone and iPad app on Apple silicon Macs.

### 1.5.0 — 2026-08-10

The design wave.

• A sharper look — new display typography and a larger, easier-reading type scale on every screen.
• Upcoming: planned days now lead the Notebook, and each circuit's Library page lists your planned days alongside your history there.
• Track Day: a visible Edit button on the day card — change circuit, date, or details any time.
• Garage: Add Bike opens full screen with the keyboard ready, and component reference notes read full-width.
• Miles and psi by default in the US — pick your own units any time in Settings.
• Sharper maps: corner numbers no longer overlap at tight complexes.
• Dozens of polish fixes across iPhone and Mac — clearer copy, bigger touch targets, better sunlight contrast.

### 1.4.0 — 2026-08-05

Plan the whole day — and the night before it.

• Overnight plans per track day: paddock camp or hotel, with a bike-security checklist that leads with the alarm and disc lock.
• Run-group timer: enter the day's rotation once, read your roll-out times all day, and get an optional heads-up 10 minutes before each slot.
• Session focus & debrief on every session card: one thing to work on, and how it went — written while it's fresh.
• Setup cards: share a day's pressures, gearing, and conditions as one clean image.
• Every planned day on one calendar — press and hold to edit or clear it.

### 1.3.0 — 2026-08-01

You reported, we fixed — this one's all about the notebook:

- New Track Day opens full height, with everything right there
- Circuit picker with search and your recent tracks
- Tire pressures in psi or bar — pick yours in Settings
- Swipe a day in the notebook to duplicate or delete it
- Bigger, clearer text everywhere — no more squinting at cut-off names
- RaceBox imports land in ride order, with a progress bar that behaves
- The lap logger's buttons now show up every single time

### 1.2.1 — 2026-07-17

A new icon for Apex Lines — the white track ribbon, the red reference line, and the amber apex dots, matching the notebook's vocabulary. Small polish throughout.
