Harry's GPS/OBD Buddy is a versatile trip computer and GPS / OBD data monitor. The trip computer records distance and time traveled, and calculates average speeds. Using the navigation module from Harry's GPS Suite, GPS/OBD Buddy will furthermore forecast arrival times using waypoints.

In addition to standard iPhone GPS functionality, GPS/OBD Buddy supports a huge set of external GPS and OBD sensors. Accessing these sensors directly, GPS/OBD Buddy gives you a detailed view not available in any other app.

Like all applications from Harry's GPS Suite, Harry's GPS/OBD Buddy uses our advanced GPS Engine. We offer Harry's GPS Buddy as a technology demo for Harry's GPS Suite for free. In case you want to do more with the data shown, check out one of the Harry's LapTimer editions.


Extensive display of GPS information: speed, height, heading, slope, accuracy, GPS update rate, latitude, longitude, lateral and lineal acceleration, a nice compass, and waypoints approached; display of trip information - both continuously and from the latest starting point; trip information includes time traveled, time without movement, average speed overall and while in movement; navigation module including waypoint management, calculation of distance to waypoint, estimated time of arrival. In case a compatible OBD sensor is connected, Harry's GPS Buddy will display wheel speed, engine RPM, fuel level, voltage of electric system, coolant and oil temperatures, throttle position, fuel consumption, power and torque developed by engine.

Great Customer Service...Good App

I really like the interface and have Harry's Laptimer Grand Prix Edition. I purchased both the In-App Add-Ons (GPS and Engine). I have a Vbox Sport, a GoPoint BT1 and a 2013 Audi S4 with APR tune. I've had a handful of questions getting the app configured and Harry has been crazy fast in responding...almost real time. I have only one real issue in that for my setup the HP and torque are not fully functional. Harry is helping me work through the issue, but other than this one minor issue, everything else works great and for the folks like me out there that like tons of data, this app is great. Thanks for making the app and please continue to make it better. If I can get the HP and torque working, it'll be a solid 5 star review from me.

Nice app… 1 issue

Very useful app with nice upgrades - I have enjoyed using it over past years. For some reason, however, now when adding a vehicle from the alphabetical drop down list, the choices for the vehicle make terminates with Nissan (no entry available for Porsche, Volkswagen, Volvo, etc).

Great start

This app is off to a great start! I love all of the details is provides about my trip. There are some usability issues that need addressed in order for me to give it more than 3 stars. In particular it is hard to enter waypoints. The application requires you to enter coordinates and does not provide a map or take addresses. So you have to go and look up the coordinates elsewhere. Since the iPhone doesn't multitask you either have to remember the coordinates or write them down in order to enter them into TripMaster. TripMaster doesn't allow you to paste coordinates. You have to use a spin wheele which is not so easy to use. If you need numbers that are very different than the ones that first appear on the wheele, you'll spend minutes spinning to the number you need.

I couldn't get the trip to stop tracking after I had reached my destination. I selected "Stop" but it kept tracking time and other stats. Maybe I don't understand how to use it? I really want to save trip stats so that I can compare trips and routes over time. I hope this feature will come soon.
