This site isn't in the App Store — instead, you can save it straight to your home screen so it opens like a real app, full-screen, with its own icon. Takes about 15 seconds.
This only works in Safari on iPhone — it won't work in Chrome, Instagram's browser, or any other app. If you got here from a text or Instagram, tap the "⋮" or share icon and choose "Open in Safari" first.
Look at the bottom of your screen (or top, on newer iPhones) for the Share icon — a square with an arrow pointing up.
A menu of options will pop up. Scroll down through the list until you see "Add to Home Screen" with a small plus-in-a-square icon, and tap it.
iPhone will show you a preview with the app name ("Key West '27") and icon. You can rename it here if you want. Tap "Add" in the top right corner to confirm.
That's it! The icon will appear on your home screen like any other app. Tap it any time to jump straight into the trip site, full-screen, no Safari bars.
