For example, you may define your home and working locations as a 'track', collect statistics on different ways chosen, and analyze / optimize the time used every day. Want to show your drive to your friends? LapTimer Petrolhead and above generates beautiful in car video recordings with all kinds of data overlaid, ready to be presented - e.g. on youtube.

No empieza a grabar con el iPhone cuando empueza la vuelta, no lozaliza bien! Pff muy mala aplicación. Si salgo de la app para grabar con el iPhone no se queda bien en segundo plano cronometrando.

I can overlook Bluetooth connectivity issues for the data and overlay, although I purchased and use recommended gps and OBD2 devices. Those are spotty at best. The app does fine of data logging and the video looks good. But when you overly and export a video the app basically won’t do anymore video viewing or exporting. Then in the photos app you can’t view the video that was exported (or any other video in your library) until you reboot the phone. The app did this with my iPhone 15 Pro and now the same with my brand new 16 Pro. I’ve deleted the app and moved on. Payed a bit more for the Garmin Catalyst but it’s much better. Harry’s lap timer is nothing but headaches.

Soldi buttati. App inutilizzabile con Kiwi 2 WiFi (WRX STI 2012, cosa che non è minimamente chiarita nella descrizione. Ho provato a usarla, ma non ha mai funzionato. Chiesto rimborso ad Apple, rifiutato anche se non ho potuto fare neanche un singolo giro o log. Sconsiglio assolutamente. Fate attenzione. Money wasted. App doesn’t work with Kiwi 2 WiFi (WRX STI), which is not clearly stated anywhere. Tried to use it multiple times — never worked, not even once. Asked Apple for a refund, they refused, even though I couldn’t use the product at all. Stay away unless you have one of the few supported adapters.

Spätestens beim Videoexport, bzw Overlay-Export lädt die App zig Minuten, ohne ein Ladesymbol anzuzeigen. Am ende steht der Speicherplatz sei zu gering, obwohl das Video unter 2gb ist (gemäss Angabe der App) und ich über 100gb freien Speicher habe. Nun habe ich mehrere Runden aufgezeichnet und kriege die Videos nicht aus der App, ausser ich mach direkten Export und habe dann kein Overlay. Wegen dem Overlay habe ich die App gekauft und es funktioniert leider nicht.

Can get the track loaded and select drive and no data is recorded. Really bummed because I loved using the app in the past and it always worked great. Tried deleting and redownloading but it still would not record any lap data.

Absolutely waste of money. Nothing syncs. No useful tutorials. 74 page PDF that makes no sense. You need an engineering degree to get this to work with a simple GoPro.
