Open Lap is a simple, no-nonsense slot car race management app for Carrera® DIGITAL 124/132 systems.
In a nutshell, Open Lap lets you
- connect your mobile device via Bluetooth using Carrera AppConnect®, or a suitable serial to USB On-The-Go adapter cable.
- take it easy during free practice, go for fastest lap in qualifying, or compete in lap or time based race sessions.
- get informed about important events, such as fastest laps or low fuel conditions, by personalized voice messages.
- adjust vehicle speed, brake force and fuel tank size for each car individually.
- measure up to three intermediate or sector times (S1, S2, S3) using Carrera® Check Lane or compatible equipment.
- send out the pace car in case of emergency, or temporarily disable lap counting during a "yellow flag" phase.
Some features, such as the start light and pace car buttons, will require Carrera® Control Unit firmware version 3.31 or higher. Carrera® Check Lane support requires at least firmware version 3.36.
The Android version is available on Google Play. You may also want to join the Beta testing program to preview unreleased versions.
An iOS version, maintained by Philipp Anné, is available on the App Store.
Open Lap is also available as a Progressive Web App, hosted at https://tkem.github.io/openlap/. To use this with Carrera AppConnect®, you'll need a Bluetooth 4.0 adapter and a recent version of Google Chrome. On Linux, at least, you'll also have to go to
chrome://flags/#enable-experimental-web-platform-features
and enable the highlighted flag.
