小蚁行车助手

This is a great app. I use it all the time for my racing and the overlay function makes for great viewing and feedback. I would recommend this to anyone! Also it's very easy to use and very quick to setup at new circuits. A*

But the delivery is disappointing. The usability is baffling, it's only recorded a few laps and has done with no video, some with no telemetry etc. Can I recommend Harry's Laptimer Simple and Reliable edition?

Very buggy app, had to do a hard restart of my iPhone while using many times as it locks the whole phone out. Sort it out Harry!!

The lap timer works sub-optimally. When it works it's very accurate against my other dedicated GPS devices. But I was at Cadwell Park recently and it recorded half my sessions and yest didn't record any at Pemvrey. Maybe user error, but hard to see that. I think there are better more reliable free lap timer apps out there.

I was frustrated by not having access to RaceChrono by having an iPhone.. I no longer care :) this is brilliant, don't worry about the price.. It's worth it, everything you want/need and more, the email support is second to none also :) thanks Harry

Having just returned from a 2 day track event. The app worked flawlessly controlling my gopro and getting obd stats via Bluetooth. So easy to use a must have product for track

Used this app for 2 years now and it's been great, they keep developing and the info it generates is easily enough for what I need.

This app far exceeded my expectations. Truly take my hat off to you guys. The overlay feature is fantastic. Everything worked and worked well without any input from yourself you just load up the track you don't have to press start stop over the finish line etc just start it once and it will start timing as auto as you go over the start finish line. Video feature is amazing and the other features an data just blows your mind. On top of all that it works! Did I say that before? Lol great app no stunning app well worth the money. If your into track days you can not be without this app. Simple as that!

Great app, compared to the price of a v-box mini this is a complete steal. Works really well, a must for any track enthusiast.

This app was a big reason for me getting an iPhone. Amazing app
