A link click and an app install happen on two different screens, seconds or days apart. Deferred deep linking and install attribution close that gap: the first carries a link's destination through the install so a new user lands on the right screen instead of a generic home screen, and the second matches that install back to the click that caused it, so a team knows which link, campaign, or channel actually drove growth. This collection covers both, platform by platform: iOS, Android, React Native, and Flutter, plus how to attribute installs from any link without IDFA. WarpLink handles deferred deep linking and install attribution as part of one SDK, alongside real-time analytics, so a click and the install it produces are already connected before you write a line of matching logic. Pick a platform to get started.
