## What is Harry's LapTimer Rookie?

Harry's LapTimer is the advanced tool for car enthusiast. It records all types of sensor data provided by your iPhone/iPod/iPad (or external sensors), combines them, and makes them available to optimize your drive. Over time, you will get insights on your car and in your driving, not known before.

LapTimer offers more than 1300 predefined tracks world wide. With its assistants, it is extremely easy to setup - just click your track and drive. It fully automates your lap timing using GPS, and presents the results to all kinds of media.

You are not limited to track driving only. 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. Even without video, recorded data can be analyzed using purpose designed views, making it easy to analyze and improve your driving performance.

Using online racing, you can use LapTimer in competition. LapTimer offers a Hall of Fame, allows watching you and your friends on track - all in real time. Compare your sector times, braking / acceleration points, and learn from each other. 

You can start with your plain iPhone in the beginning and add external GPS and OBD II sensors later, step by step, and as you need it. LapTimer itself comes in three different editions: LapTimer Rookie is the entry level with all you need for lap timing; LapTimer Petrolhead is the advanced version including lots of video features, and LapTimer Grand Prix is the edition for professionals including Multi Cam recording, Health Kit integration, and advanced sensor and analytics functionality. 

Please note that functionality depends on your device, the LapTimer edition chosen, and sometimes even external sensors added (like OBD II). Please visit our web page to get the full story. All edition can be upgraded later, all editions come with native iPhone and iPad support. 

There are quite expensive stand alone solutions for track days available. Be smart and own the leading edge tool simply by using your iPhone and LapTimer.

### 5/5 — Jetzt auch mit CarPlay

*2025-06-21, version 25.0.1*

Mega App jetzt nun endlich auch für CarPlay freigeschaltet. Super Support wenn man eine Funktion mal nicht findet. Auch die 10tel Sekunde genau verglichen mit dem offiziellen RCN Timing.

### 1/5 — Schrott

*2025-06-15, version 25.0.1*

Spart euch das Geld. Schlimmste App die ich jemals gesehen habe.

### 1/5 — Finicky, legacy, doesn’t work well

*2025-02-27, version 24.9.1*

This app is not easy to use and even if you learn how to use it, it doesn’t function properly most of the time. I did 50 laps at Laguna Seca last weekend with my phone connected to my GoPro and my OBDLinkMX+ and neither the GoPro footage nor the OBD data was recorded for even a single lap. 

At the beginning of each session I carefully made sure everything was configured correctly, thinking “maybe it will work this time”, but no. This app does not work well at all. 

It is a legacy app that hasn’t been updated very well over time and is lacking in reliability/ease of use. I do not recommend wasting nearly $30 on it. If you are just looking to time your laps, the super basic version might be okay to use. 

Personally I wish I had listened to the reviews before wasting my money on this app. Do not make the same mistake I did.

### 1/5 — Rubbish

*2023-04-21, version 24.7.1*

Couldn’t even get this started, should be just start/stop review data… but awful layout and requires add on’s for everything, basically they just want you to buy the full version. Don’t bother!

### 1/5 — Absolute garbage

*2022-11-20, version 24.7.1*

I downloaded this app last year for a DE weekend. At the time, I found it very user in friendly and annoying, but at least it saved my videos and times. Yesterday I used it again for the second time: it froze in the middle of data transfer to my phone, crashed, and then proceeded to delete an entire day worth of lap videos. And then it did it to me again today. RIP video of COTA PR time. Harold and his developers should be ashamed to be selling this app. It is absolute rubbish.

### 3/5 — Quit giving me times.

*2022-04-06, version 24.5*

I loved it for the last 5 years but it quit registering. Never started going past start finish. No time.

### 1/5 — barely ever works

*2021-10-26, version 24.5*

had this along time. used to work well but now seems to never work. interface is very confusing and hard to achieve the given task.  starting the timer is temperamental. seems to often not run or otherwise incorrectly start or end the lap.  the last 4 track days i have not been able to record a single lap time that i think was realistic dependable data.

### 1/5 — Terrible interface. It won’t work when you need it

*2021-03-07, version 24.0*

Cons:
- laps/race don’t start automatically. Nor is it obvious how to turn the race on. You have to go to the Race section, set up a driver, then the car, and then figure that the app will be waiting until you drive off. Extremely unintuitive.
- finding your results is impossible. You have to go to the Analysis -> Lap Times, and locate a green dop next to the time (which indicates it’s you 🤦🏼‍♂️)
- it gets worse, each time you go out for a new session, the Race needs to be manually triggered by setting the previous run as reference. 
- but what is the worst is the deception that a new session is recoding and working.  You think you have triggered a new session and have put your phone away. Only to return to the pit to realize that app has silently produced some hidden alerts after you’ve triggered the new session and put the phone away! IMO this defeats the whole purpose.  

Pros: 
- when it does work the stats are well presented

In summary, out of 5 sessions, I was only able to record 1. Terrible. Save your money.

### 1/5 — Absolute waste of money

*2020-12-20, version 24.0*

This app does not work at all it is a complete waste of money DO NOT BUY

### 5/5 — 👍🏻👍🏻👍🏻

*2020-09-02, version 23.0.11*

Super App! Ich benutze sie auf der Nordschleife und bin sehr zufrieden was man für 10 Euro kriegt 👍🏻 erstmals ist es etwas schwer rein zu finden aber wenn man drin ist einfach nur super!
