Know Which Link Brought Every Install: Appy’s iOS and Android SDK
Appy now follows your links past the app store. The new SDK shows installs, in-app events and revenue for every link, QR code and campaign, and opens new users on the right screen.
Clicks were never the goal
Until now, Appy showed you who tapped your links. The answers you actually need come after the tap: did they install, did they open the app, did they buy?
The Appy SDK for iOS and Android answers all three. It’s available now on the Enterprise plan.
Tap, install, open
Someone taps your link
In an Instagram story, an email, an SMS or a QR code on a poster.
The right store opens
If the app is already on the phone, it opens right away.
The app opens where the link pointed
The product, the offer, the invite. And the install is credited to your campaign.
One link, every phone

What changes for your team
You see which creator, poster or email brought paying users, not just traffic.
New users stop landing on a generic home screen. They open the app on exactly what your ad promised, which is where first sessions are won or lost.
And rewards get simpler: pay referral and creator bonuses only for confirmed installs.

Frequently asked questions
Which plan includes the SDK?
Enterprise, which also includes everything in Business with no link limits. Store routing, QR codes and click analytics work without the SDK on every plan.
Does it replace AppsFlyer or Adjust?
Not for paid ads on Meta, Google or TikTok; keep your MMP for those. Appy measures the links you own: campaigns, QR codes, creators, email, SMS and referrals.
Is it privacy-friendly?
Yes. No advertising IDs, no stored IP addresses, and one switch for users who opt out. When someone asks to be forgotten, their data is deleted.
