Hotel Guest Apps Across iOS and Android
Quick answer
Hotels should build guest apps from one codebase so iPhone and Android guests get the same features. Add a web version for guests who won't download an app. Offer mobile check-in, digital keys and requests in the guest's language. Upsells add revenue. Connect the app to your hotel management system.
Hotel guests arrive with every kind of phone, from every country. A guest app that only works on one platform, or only in English, leaves many of them out. A cross-platform app built from one codebase reaches iPhone and Android guests alike, and a web version catches those who won't download anything for a short stay.
Key Takeaways
- Guests use both iPhone and Android, so one codebase should serve both.
- A web version helps guests who won't download an app.
- Mobile check-in and digital keys shorten front desk lines.
- Requests and chat in the guest's language improve the stay.
- Upsells like late checkout and upgrades add revenue.
- Connect the app to your hotel management system for real-time accuracy.
