Smler is a deep linking platform for mobile app teams. One link opens the right screen in your iOS or Android app, sends new users through the App Store or Play Store and still lands them on the right screen after install (deferred deep linking), and falls back to the web on desktop. It includes iOS Universal Links and Android App Links, install and campaign attribution, links that never expire, custom domains, QR codes, and a REST API with webhooks. Built as a drop-in replacement for Firebase Dynamic Links, with 25,000 free attributed installs every month and flat pricing instead of per-install metering.
