Hey there! Here's what's new in RaceTools 2.3: • Address Search in E85 Locator: Stop panning the map. Search any address to find nearby E85 stations in seconds, or tap once to jump to where you are. No location permission needed. • Calculator Memory: Your car's setup is remembered. Tank size, ethanol targets, and fuel content are prefilled from your last calculation every time you open the app. Just enter your current fuel level and go. • Calculator Insights: Tap the info icons next to any field for a plain-English breakdown of what each value means and why it matters. We also removed the shake to report gesture that was accidentally triggering the feedback page. Sorry for the trouble. Thanks for riding with us. Enjoy the update!
