## What is RaceTools?

RaceTools is the toolkit built for drivers who take their build seriously. Calculate your ethanol mix, find E85 stations without sharing your location, track every mod, and plan your routes. All in one app, built by a car guy for car guys.

Key Features:

1. Ethanol Calculator: Get the precise pump gas and ethanol amounts to hit your target blend in seconds. Your car's setup is prefilled from your last calculation so you're never starting from scratch. Tap any field for a plain-English breakdown of what it means.
2. E85 Locator: Find E85 stations near any address without sharing your location. Search by address, use your current location, or search the area around you. Community-reported availability keeps the data honest.
3. Route Planner (Premium): Know your E85 stops before you leave the driveway. Plan your route around stations, save your last 5 routes, and never get caught short on a drive.
4. Car Build Tracker: Every mod. Every part. Every cost. Track your full build history in one place, because your build deserves better than a notes app.
5. Tire Size Calculator: Compare tire sizes before you commit. See diameter differences instantly and protect your AWD system from unwanted wear.
6. CarPlay Support (Premium): Your favorite RaceTools features, right on your dash. Hands-free and always within reach.
