Do I need an app from the store?
Use GreenRah in the browser, or install the Android app from Google Play. iPhone is coming soon.
On Android you can install GreenRah from Google Play: https://play.google.com/store/apps/details?id=com.greenrah.app
The iPhone app is not in the App Store yet. Until then, use Safari at greenrah.com/app, or add the site to your home screen.
The web map at greenrah.com/app stays free for everyone. You do not need a store download to plan a Heat Smart or Accessible walk.
Use an up to date browser if you stay on the web (Safari on iOS, Chrome on Android). Allow location when you plan or walk.
Keep the tab or the Android app open while walking so navigation can update.
