Lap Logger: Sim Racing Times

New in 1.3: compare laps side by side and track your race pace lap by lap — with tyre wear, damage, and pit stops now captured automatically from F1 25.

LAP LOGGER

The lap journal for sim racers — with automatic capture and deeper analysis.

Log your Time Trial and Race laps across all 25 rounds of the 2025 or 2026 F1 season, track your personal bests, and keep every setup and note in one place. Lap Logger can capture your laps for you straight from the game — and now it helps you make sense of them.

NEW — LAP & RACE ANALYSIS

Built on the precise data auto-capture records:

• Compare laps side by side and see exactly where you gain and lose time
• Race analysis: your cumulative race time and your gap to your best lap, lap by lap
• Tyre wear and pit stops now captured from F1 25 telemetry

AUTO-CAPTURE (F1 25)

Connect Lap Logger to F1 25 over your home WiFi and it logs your laps automatically as you drive:

• Every valid lap in the session — not just your best
• Tyre compound on each lap
• Your exact car setup, captured from the game — no more typing it in
• Automatic track and session detection (Time Trial and Race)
• A pre-filled lap at the end of each session — save, edit, or discard

One-time setup: pop your iPhone's address into F1 25's telemetry settings and you're connected. It all happens on your local network — nothing is uploaded, nothing leaves your device.

Prefer to log by hand? Manual entry is still here, exactly as before.

DESIGNED FOR FANS

Every screen mirrors the visual language of motorsport: bold typography, race-team colour palette, circuit outlines, and country flags. Built to feel like a piece of equipment in the paddock, not a generic checklist app.

PRIVACY-FIRST

Lap Logger has no accounts, no ads, and no tracking. Auto-capture uses your local WiFi to receive telemetry from your console, but the app never connects to the internet and never sends your data anywhere — your laps stay on your iPhone, like a paper notebook.

REQUIREMENTS

iPhone running iOS 17 or later. Auto-capture requires the F1 25 game with UDP telemetry enabled, on the same WiFi network as your iPhone.
