Trending graphs defaulting to comparing predictions with ETs Dr. Dial-in Trending graphs include several out of the box comparing predictions with ETs. This allows you to see how well the DDPE has been doing. You can change the graph to show trending of any pass details. Sophisticated Dr. Dial-in Prediction Engine (DDPE) Calculations are based on Patrick Hale's Motorsports Standards Atmosphere and Weather Correction Methods. The same mathematical algorithms use by Engine Dynos. Dr. Dial-in doesn't stop there. The effects of wind speed and direction are complex and to help you determine the influence it will have on your pass Dr. Dial-in presents your prediction in perspective of a 0 - 20mph range. Wind feels a little gusty? Favor a dial-in closer to the 20mph prediction. Prediction Tuning Dr. Dial-in predictions are more than just static mathematical algorithms, You can tune the prediction criteria effecting the prediction results. As you're adjusting the prediction criteria you can watch the difference between your most recent ETs and the predictions change for instant feedback if your tune is an improvement. If you like the results save the changes and your future predictions are now tuned. ## Key features - Log passes for multiple vehicles - Quick access to pass information - 1/8, 1000', 1/4 mile predictions - Trending graphs comparing predictions with ETs - Sophisticated prediction engine - Prediction tuning - Customizable data views ## Recent user reviews (6 of 6) All indexed reviews: https://appshunter.io/ios/app/dr-dial-in/id1355567022/reviews.md ### 1/5 — Not useful for me *2024-06-09* The closest weather station option for my local track is over 20 miles away in a different town at a different elevation. Have no use for the app. ### 5/5 — Incredibly accurate *2021-09-11, version 1.4.0* I drag race a street-driven car, and while I believe this app was created for more purpose-built drag cars, it has been an amazing tool to use at the track. Once I had tuned the prediction mode to my ETs pretty well, it would often accurately predict within thousandths my first pass of the day. On day 2 of a big race where you maybe don’t get a time hit, this app can be a lifesaver. Or a round-saver, as the case may be. If you’re patient and accurate when you are getting tracks and cars set up in the app, it will be accurate with its predictions for your ETs. Great app, I hope it continues to stay available in the app store. ### 5/5 — Very accurate! *2021-08-16, version 1.4.0* I put in about 5 time slips into the log book, it told me I was going to run a 6.568 and my car ran a 6.578 so only one off. I’m okay with that! Being one above the predicted time is better than being one below and breaking out relying on what the app told me! ### 2/5 — Use for log book only *2019-09-30, version 1.4.0* Nice electronic log book. Predictor doesn't work to well. Doesn't take i to consideration water grains and that it the 1 of the 2 measurement that effect my car the most. ### 5/5 — Dr. Dial-In works awesome *2019-06-10, version 1.4.0* I had this app on Android phone, works incredible and is very accurate Just downloaded for IPhone and same results. Awesome App. ### 5/5 — Very nice app *2018-06-26, version 1.1.0* Works for me ## Frequently asked questions about Dr. Dial ### What is Dr. Dial-in?
