DragTuner Log Book & Weather

The DragTuner run logger is the core of the app. It lets users log timeslips, conditions, and events for both pre-loaded US tracks and user-added tracks. Choose between ¼ mile and ⅛ mile and enter your timeslip data. Get Weather can fetch up-to-date weather based on your location, returning temperature, density altitude, humidity, barometer, dew point, wind speed and direction, and water grains, plus track temperature and notes. The Notes screen stores car setup details such as estimated ET, dial in, delay, tire pressure, and notes, and all runs can be filtered and sorted with the Filter Run feature.

Version 2.0.0 introduces ET Prediction and car configurations. ET Prediction estimates ET from three prior runs and current weather, while car configurations let you separate runs by vehicle and add custom fields per vehicle. Additional features include the ability to filter and sort runs, access weather data via Get Weather, and store comprehensive race data, weather, and notes. The extension requires a subscription with auto-renewal and a 7-day free trial, with Terms of Use and Privacy Policy available for reference.
