## What is DragTuner Log Book & Weather?

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.

DragTuner requires a subscription to use the application. DragTuner subscriptions give the user full access to the app and they are auto-renewing. Payment will be charged to your iTunes account at confirmation of purchase. The subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours of the end of the current period at a price of either monthly or yearly price depending on your subscription. Subscriptions may be managed by the user and auto-renewal may be turned off by going to Account Settings on the device after purchase. A free trial period of 7 days is included with the subscription. After the trial period expires, you will be charged at the monthly or yearly price depending on your choice when you sign up.

### 5/5 — Father’s Day

*2025-08-10, version 3.2.3*

Qualifying round 1

### 1/5 — Not worth it

*2025-07-11, version 3.2.3*

This thing is way off not worth it

Nice features

### 5/5 — Awesome app

*2023-05-07, version 3.1.0*

Has really helped my drag racing

### 2/5 — No good

*2021-09-11, version 2.12.0*

Can’t rely on it to refresh it self when you need it ! Been trying to use it, but here comes round 3 and the dam thing is froze up

### 2/5 — Weather data

*2021-08-22, version 2.12.0*

Weather data does not update fast enough. Can’t wait 10-15 minutes to log weather. I had to wait to get weather for my run

### 4/5 — Great app with potential!

*2020-06-14, version 2.12.0*

Loving the app for keeping logs of everything at the track. It would be very nice if you could add a cloud backup option to iCloud, box, Dropbox, or even a local backup for when you inevitably have to switch phones. 

It would also be nice if you could flag a run for this like hit the brakes, lifted, or issues so you can identify it from the run screen without having to go into each run and check the notes.

### 5/5 — Trying it again

*2019-08-04, version 2.7.0*

Had issues with it to start, but after a few updates it’s working great. Not quite as accurate as track based software of course, but for the price it can’t be beat.
