The DragTuner run logger is the core of the mobile app. It allows users to log their timeslip, conditions, and other various information. Choose a track from one of the many pre-loaded tracks in the United States or add your own. DragTuner allows you to add the event as well which will be saved for later runs. Choose between ¼ mile and ⅛ mile and enter your timeslip.

Version 2.0.0 introduces some features such as ET Prediction and car configurations. ET Prediction allows a user to predict their ET based on three previous runs and the current weather. Car configurations allow the user to separate their logged runs by vehicle as well as add custom fields for each vehicle.

Track and weather conditions are key to your race car’s performance. When adding a run, under the conditions tab, click Get Weather to get the latest weather based on your location. DragTuner uses location services in your device to get your location and query the closest weather station in your area. We return the following fields: temperature, density altitude, humidity, barometer, dew point, wind speed & direction, and water grains. On this same screen, there are also fields for track temperature and notes.

The notes screen, which can be found under the “Notes” tab on the “Add Run” screen, is used for storing car setup notes. Currently we support the following fields: estimated ET, dial in, delay, tire pressure, and notes.

All of the fields described above can be filtered and sorted upon by using the Filter Run feature by pressing the filter icon on the home screen in the top righthand corner.

Not worth it

The app is great if you want to digitally log every run and compare. But it’s not worth 5.00 a month. Does give you weather but not at your track just the closest city witch could be 10-15 miles away. It’s a great app just not worth the money

Developer Response ,

The app is $3.99 per month or $2.92 if you subscribe yearly. Thanks for trying out the app. We will be adding ET prediction very soon if you are interested.
