Apex Lines: Track Day Notebook

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.
