Frequently Asked Questions

Quick answers to the most common questions about LapBrain.

Getting started

What data loggers does LapBrain support?

The app syncs straight from AiM Solo 2 and Solo 2 DL data loggers over WiFi and from a RaceBox Mini S or Micro over Bluetooth. You can also bring an AiM (XRK/XRZ), MoTeC (LD), or RaceBox (VBO, downloaded from the RaceBox web app) file from any browser. See the Data Logger Setup section for step-by-step instructions: AiM, MoTeC, RaceBox.

How long does processing take?

Most sessions process in 30–60 seconds. Sessions with many laps may take slightly longer. See Your First Session for what you'll see while the session processes.

Do I need GPS data?

Yes. LapBrain requires GPS latitude and longitude channels for track maps and corner analysis. Without them, LapBrain cannot provide Turn phasesTurn phasesFive measurement regions used to locate where something happened in a corner: Entry, Decel, Maintenance, Accel, and Exit. or coaching. Check your data logger's setup guide to verify GPS is enabled.

Can I use my phone as a data logger?

Phone-based data logging is not currently supported. LapBrain works with dedicated hardware data loggers from AiM and MoTeC, and connects directly to RaceBox GPS devices over Bluetooth.

Analysis

What is a "focus recommendation"?

Your Focus recommendationFocus recommendationThe corner or riding pattern LapBrain puts forward for you to review next. s are coaching suggestions ranked by how clearly the pattern appeared, the measured time opportunity when one is available, and relevant session history. The top item is the current priority in your data; several are listed so you can pick one that fits your session. See Understanding Coaching and Acting on Coaching.

Does LapBrain tell me what I'm already doing well?

Yes. Wins appear before coaching and name the measurement behind them, such as a narrow entry-speed spread or recorded brake overlap. If you set Rider Background under Settings → Profile → Rider Background, LapBrain uses that context to make the wording more relevant. See Reading Your Debrief and the guides for riders coming from the street or from cars.

How does pace percentile work?

Pace percentilePace percentileHow your best lap ranks among riders in the same bike class at that track; 75 means faster than about 75% of that group. compares your best lap time to other riders on the same bike class at that track. See Pace Percentile for what the number means and how to read it alongside your own lap history.

What are turn phases?

LapBrain breaks each corner into five Turn phasesTurn phasesFive measurement regions used to locate where something happened in a corner: Entry, Decel, Maintenance, Accel, and Exit. : Entry, Decel, Maintenance, Accel, and Exit. The phases locate different measurements; brake and throttle claims still require those recorded channels. See Turn Phases for how to read them.

What are coaching threads?

A Coaching threadCoaching threadAn issue followed across comparable sessions, such as entry-speed spread at T5 or section-time spread through the esses. starts when LapBrain identifies an issue it tracks across sessions. Comparable sessions extend it whenever LapBrain checks the same issue again. See Coaching Threads for the full lifecycle.

Why do my corner numbers differ from the track's official numbering?

LapBrain's corner names and numbers may differ from a circuit's official map, especially where the official layout skips numbers or names a corner instead. Use the in-app map to see which physical corner each designation refers to.

Why do I see separate PB tiles for each bike?

The career dashboard keeps Per-bike personal bestPer-bike personal bestYour fastest lap at a track on a specific bike, kept separate from PBs set on your other bikes. tiles separate for each bike, so a PB set on one does not replace the benchmark for another. Unassigned means no bike is selected for that session. Assign the bike to include the session in that bike's history; until then, LapBrain compares it with sessions in the same bike class.

Using LapBrain effectively

How do I get the most value from LapBrain?

Follow the briefing-session-debrief loop: review your Focus recommendationFocus recommendationThe corner or riding pattern LapBrain puts forward for you to review next. before riding, focus on one thing during your session, and upload while the session is fresh in your memory, which makes the debrief easier to act on. Uploading late or out of order changes nothing: sessions are ordered by when you rode them. See Acting on Coaching for the full workflow, and Track Preparation for building a pre-session plan.

How many sessions do I need before comparisons appear?

Cross-session comparisons start once you have two comparable sessions at the same track. More sessions give the history and trend views more to work with. See Comparing Sessions.

Should I upload every session, even bad ones?

Yes. Uploading every session keeps your day and history views complete. Comparisons can show measured changes in pace, consistency, or specific corners; the telemetry does not by itself identify whether traffic, conditions, fatigue, pressure, or something else caused the change. See Day Review for multi-session analysis.

Data & privacy

Who can see my data?

Private by default. Your telemetry, lap times, and analysis are visible only to you unless you choose to share a session with a friend. Shared sessions are visible to those friends, and you can stop sharing at any time. Aggregate statistics (like Pace percentilePace percentileHow your best lap ranks among riders in the same bike class at that track; 75 means faster than about 75% of that group. ) use anonymized data and never reveal individual riders. This covers your riding data; for the separate question of how LapBrain measures app usage, see below.

Does LapBrain track how I use the app, and can I turn it off?

Yes to the first, and yes to the second. Separately from your riding data, LapBrain records usage data (which screens and features you use) so I can see what riders actually use and what gets in the way. It's linked to your account, it's never sold or shared with advertisers, and it never includes your lap data, GPS traces, or uploaded files.

You can turn it off any time in Settings → Privacy → "Share usage data to help improve LapBrain". Automatic crash and error reports are a separate system that this setting doesn't cover. Those help me find and fix bugs. See the Privacy Policy for the full detail, including the legal basis if you're in the EEA or UK.

Can I delete my data?

Yes. You can delete individual sessions or your entire account from the Settings menu. Deletion is permanent. See Delete Your Account for the step-by-step, the 30-day deletion window, and what to do if you can't sign in.

What happens to my other devices when I change my password?

By default, changing your password signs you out everywhere else: your current device stays signed in, and every other session is ended. Leave the Sign out other devices option checked (in Settings → Account → Change Password) if you think someone else may have access to your account. Uncheck it to keep your other devices signed in. Resetting a forgotten password always signs out every device. You'll sign back in with the new password.

Troubleshooting

My session shows "Unknown Track" or appears under "Other Sessions"

This means LapBrain couldn't identify the track from your GPS. The signal may have been poor, or the track may not be in LapBrain yet. Your session still processes: it appears under Other Sessions in your session list and shows Unknown Track in the session view.

Uploading more sessions will not add a missing track. If you expected your track to match, email me at [email protected] with the track name and location. I will take a look and add the track if it is missing.

My lap times don't match my data logger's display

LapBrain may re-cut laps if the start/finish position in your data doesn't match the track's actual start/finish line. This ensures consistent comparison across sessions and riders. The total session time will be the same; individual lap boundaries may shift slightly.

Processing failed. What do I do?

Check that the file is XRK, XRZ, LD, or VBO and that it opens in your data logger software. If it still fails, email me at [email protected] with the file attached.

LapBrain never gets past the loading screen

What to do depends on whether you are using the LapBrain app on your phone or LapBrain in a web browser.

In a web browser

If you land on a screen saying "LapBrain can't finish loading", tap Try again. If that does not clear it, close LapBrain and open it again. A screen saying "LapBrain can't start in this browser" means the browser itself is too old. Update Chrome, Safari, Firefox or Edge to the latest version and open LapBrain again.

In the phone app

If the app stays on the loading spinner and then shows a screen that says "LapBrain can't start on this device", the web engine on your phone (the part that opens web pages) is out of date and can't run LapBrain. Updating it fixes this.

On Android, update Android System WebView and Chrome from the Play Store:

  1. Open the Play Store app.
  2. Search for Android System WebView and tap Update if an Update button is shown.
  3. Search for Chrome and tap Update if an Update button is shown.
  4. Fully close LapBrain (swipe it away from your recent apps), then open it again.

On iPhone, update iOS:

  1. Open Settings.
  2. Tap General, then Software Update.
  3. Install any update that is offered.
  4. Fully close LapBrain, then open it again.

If your software is already up to date and the screen still appears, fully close LapBrain and open it again. If it keeps happening, contact support at [email protected] with your phone model and its Android or iOS version.
