Our history

FaQs

Whether you're just getting started or exploring advanced features, here are the most common questions we get about Lapper. From setup and subscriptions to real-time communication and data sharing — everything you need to know, answered clearly

  • How does lap tracking work?

    Lapper uses your phone's GPS to detect every crossing of the start/finish line you place on the map. No external hardware required.

  • Do I need to hold the phone while driving?

    Not at all. Just keep it safely in your pocket or secured in the kart. Make sure it has clear sky visibility for accurate GPS signal.

  • Can I use Lapper without internet?

    Yes. Basic lap tracking works offline. However, real-time features like live audio and data sharing require an internet connection.

  • What is Coach Mode?

    Coach Mode enables real-time audio communication and data sharing between two users with a single subscription. Just scan the QR code and you're connected

    Absolutely. It’s two-way voice communication — ideal for coaches, spotters, teammates, or just riding with a friend.

    Yes - Coach Mode only. For stable audio, we recommend not putting the app in the background during a session.

    Lapper provides real-time voice messages with insights like lap comparisons, performance gains, and pacing info — directly in your ear.

    Yes. Choose between lap vs. previous, lap vs. best, or a hybrid mode. You can also adjust the message frequency and detail level.

  • Is Lapper available in multiple languages?

    Yes. Lapper supports over 30 languages, including English, Spanish, German, Italian, Japanese, and more.

  • How much does Lapper cost?

    Lap tracking is free. Coach Mode (voice + data sharing) requires a subscription: 5,99€/month or 44,99€/year.

  • We need two subscriptions for Coach Mode?

    No — a single subscription covers both you and your partner (coach, spotter, or teammate).
