Free Android Auto Performance Calculator
I just published a free android automobile performance calculator. Let me know if you find any errors or have suggestions for improvement. I'm pretty proud of how well the corner balance feature turned out.
Automobile Performance Calculator designed for the road racer, drag racer and car enthusiast.
This app has 13 pages of calculators:
Enter wheel weights into the Corner Balance Calculator and it gives Cross Weight, Cross Weight%, Wheel Weight Corrections, Wedge and Bite.
The Drag Race Calculator estimates Elapsed Time (ET) and Trap Speed from horsepower and will derive horsepower from ET or Trap Speed. It will also give weight transfer at launch.
The Horsepower Calculator will give HP from torque or torque from HP, HP at altitude, Flywheel HP from Wheel HP, Wheel HP from Flywheel HP and Estimated Top Speed with Added HP.
The Torque Calculator will give Drive Wheel Torque, Wheel Thrust, Acceleration and Weight Transfer.
The Fuel Economy Calculator gives miles per gallon or kilometers per liter.
The Speedometer & Odometer Calculator will calculate their error rates.
The Conversions Calculator will convert both ways: Miles/Kilometers, Foot-Pounds/Inch-Pounds, Foot-Pounds/Newton-Meters, PSI/BAR.
The Weight Transfer Calculator will give Front-to-Rear and Lateral Weight Transfer.
The Alignment Calculator will convert Toe Inches to degrees and Toe degrees to Toe Inches.
The Skid Pad g Calculator will give Average Lateral g around a skid pad.
You can also calculate Brake Specific Fuel Consumption, Engine Air Capacity and estimate the diameter and width of a tire from it's sidewall markings.
The Car Calculator[sup]©[/sup] is free and available here in the Google Play Store. Searching for 'Rob Robinette' is the easiest way to find it in a sea of car 'financial' calculators. You can also download the latest version directly: Car Calculator for Android apk

I developed it. I'm learning to develop for Android so I translated my AutoMath and Corner Balance xls spreadsheets and some of the Javascript web calculators for Android. I also published a 'Headphone Calculator' for headphone audiophiles.

Perhaps when I get my turbo install completed I will test your HP portion of the app.

I added a Dyno Correction Calculator which gives SAE, MSA and STD correction factors and calculates corrected horsepower. It's listed on the app's main menu. The corrections include humidity.
