App Store Connect metric
Redownloads
Apple counts a redownload when someone who downloaded the app before taps to download it again. Here's why that matters for campaigns.
Definition
The total number of redownloads of your app. Counted when a customer taps the redownload button; doesn't include auto-updates or device restores.
Where to find it
App Store Connect › Analytics › Acquisition
The common mistake
Redownloads count in total downloads and in Apple's conversion rate. A campaign aimed at past users can show a strong conversion rate while bringing few new people.
What to use it for
Measuring win-back. Compare redownloads before and after a re-engagement campaign or a big update.
