# AppPage > A OneLink generator for mobile apps. One link detects the visitor's device and in-app > browser, then routes them to the App Store, Google Play, or a web fallback, instead of > leaving them on a dead end. AppPage exists because a single app store URL cannot serve every visitor. An App Store link is useless to an Android user, and neither store link opens correctly from inside Instagram's or Facebook's in-app browser on iOS. AppPage resolves the right destination at click time and provides an escape route from in-app browsers that cannot hand off to the App Store. ## What it does - Device detection: routes iOS to the App Store, Android to Google Play, desktop to a web fallback or landing page - In-app browser escape: detects Instagram, Facebook, Messenger and Threads webviews on iOS, where App Store links silently fail, and serves an interstitial that escapes to the store - Landing pages: a hosted page per app with screenshots, description and store badges - Analytics: clicks by platform, country and in-app browser - QR codes: for the same link, for print and offline use - Custom domains: serve links from your own domain - Store compliance pages: privacy policy, terms and app-ads.txt hosting ## Who it is for Mobile app developers, indie makers and app marketing teams who send traffic from social media, email or print to app store listings. It is a replacement category for Firebase Dynamic Links, which Google shut down in August 2025. ## Pricing - Pro: $5/month or $50/year. For creators with multiple apps. - Advanced: $9/month or $90/year. For agencies and power users.
