Common questions

Yes. Offline timing is completely free with no restrictions. You can run unlimited events, heats, and participants without paying a cent. The only paid feature is the optional online results dashboard ($5 + tax per meeting).
During the beta period the online feature is free to use. Once LapBeeps leaves beta, online meetings will cost $5 + applicable tax per event. Offline timing stays free forever regardless.
A laptop to run LapBeeps, and an OpenStint decoder connected to your timing loop. Transponders go on each car. Total cost for a complete setup is well under $100 — see the Hardware section above.
No. With online sync enabled, participants open a web URL (or scan a QR code) on any phone or browser to see live results. No app install needed.
Absolutely. All core timing runs locally on your laptop. Internet is only required if you activate the optional online results feature for a specific meeting.
OpenStint is an open-source transponder decoder system built for affordable, reliable lap timing. The same author who created OpenStint also built LapBeeps — they work together seamlessly out of the box.
A Linux AppImage is coming soon. macOS and Windows are available now.
All data is stored locally on your computer in standard JSON files under ~/Documents/LapBeeps. You own your data. If you use online sync, a copy is streamed to regional servers for the duration of the event.
