MotoLAP app for iPhone and iPad

It is a measurement app for gymkhana competitions and time trials for each unit.
If you use a dedicated sensor transmission terminal, you can measure accurately with an accuracy of 1/500 second.
One lap can be measured by dividing it into up to three sections.
There is a race mode (sending terminal required) for a fee (in-app purchase: 1 day unit).
In race mode, the data of multiple people is aggregated and displayed in the cloud.
Just by registering the group and nickname, you can notify the ranking and lap update.
People who use the same sensor terminal are considered as members.
Up to 6 can be divided into groups, and each group is totaled.
Race data is saved and can be viewed within a month.
If you dont have a sending device, you can try it in demo mode (free).
