Getting Started with Lap Tracker

Download Lap Tracker from the Google Play Store and open the app. You'll be greeted by a short onboarding flow that walks you through the basics.

Your first step is to create a vehicle. Tap the vehicle section and enter your car's year, make, and model. You can add multiple vehicles if you drive more than one car on track.

Once your vehicle is set up, you're ready to log your first session.

Tap the Track Session button on the home screen to start a new session. Select your vehicle, then pick the track you drove.

Enter the essentials: your best lap time, number of laps, and the date. You can also add weather conditions and notes about how the session felt.

For a quick log, that's all you need. But if you want the full picture, expand the setup sections to record suspension settings, tire pressures, alignment, aero, and powertrain details. Every field is optional, so fill in what matters to you.

Tip: The more data you log consistently, the more useful your analytics will become over time.

Navigate to the Tires section to create tire sets. Enter the brand, compound, and size for each set.

When logging a session, select the tire set you used. Lap Tracker will automatically track heat cycles and distance driven on each set, so you always know where your tires stand.

Over time, you'll be able to see exactly how many sessions and kilometers each set has been through, helping you plan replacements before they lose grip.

Once you have a few sessions logged, head to the Analytics section to visualize your progress.

You'll find:

• ▸ Lap time progression — see how your times improve across sessions at each track
• ▸ Session comparison — compare setup details side by side to see what changed
• ▸ Temperature sensitivity — understand how ambient and track temps affect your times
• ▸ Pressure trends — track how tire pressures correlate with performance

Pro users get access to deeper chart options and additional trend analysis.

Don't retype your setup every session. When creating a new session, look for the "Copy setup from previous session" option near the top of the form.

This pulls in all the setup fields from a prior session, so you only need to update what you changed. It saves time and reduces errors, especially for drivers who make incremental adjustments between sessions.

Tip: Use copy as your starting point, then adjust only the values you changed for a clean before-and-after comparison in analytics.

Keep your track car in top shape by logging maintenance events. Go to the Maintenance section and set up service types for the work you do regularly: oil changes, brake fluid flushes, brake pad replacements, and more.

Log each event with the date and mileage. Set warning thresholds based on distance or time interval, and Lap Tracker will let you know when service is coming due.

Default service types are included out of the box, but you can customize them to match your car's needs.

Protect your data by creating regular backups. Go to Settings > Backup and tap "Create Backup." This generates a JSON file containing all your data: vehicles, sessions, tires, maintenance records, and settings.

To restore, use "Restore from Backup" and select a backup file. This works across devices, so you can transfer your data when upgrading to a new phone.

For spreadsheet analysis, use CSV Export (Pro feature) to export your session data in a format that opens directly in Excel, Google Sheets, or any data tool.

Tip: Back up before every app update and save the file to cloud storage (Google Drive, Dropbox) for extra safety.

The quality of your analytics depends on the quality of your data. Here are some habits that make a big difference:

• ▸ Log hot pressures — check tire pressures right after your session while they're still warm. This gives you the most meaningful pressure data for comparison.
• ▸ Record track temperature — ambient and track surface temps significantly affect grip levels and lap times. Logging them helps explain variation between sessions.
• ▸ Be consistent — log the same fields every session. Consistency makes trends visible. If you track front-left camber once but skip it the next three sessions, the data can't tell you much.
• ▸ Use notes — write down what felt different. "Car understeering on entry of T3" is the kind of context that makes setup data actionable later.
• ▸ Change one thing at a time — when adjusting your setup, change one variable per session so you can isolate its effect in analytics.
