It does what it’s supposed to. I compared the times with a stopwatch and it’s very close. If it’s off, it’s less than half a second off.

Klasse App
Atualizaram agora para nível de inclinação, gostei bastante. Mas sinto falta de poder adicionar mais do que 2 setores por circuito, e informação de velocidade mínima. Seria possível fazer essa Melhoria “LapTrophy”?
ミニサーキットのタイム計測に使っています。 日本語に対応してもらえると私も課金しますし、日本でのシェアが広がると思います。
