The project was about the receipt scanner iOS App. The main goal was in-app subscriptions but the client had a problem with reporting in-app purchases. So while it fixing we decided to test app installs instead.
What's done:
Different audiences were tested for the improvement of the result, including the LAL of those who already installed the app.
Total spent: $1 719,03
Reach: 92 387
Mobile App Installs: 540
Per Mobile App Install: $3,18(last result was $1.60-2.14)
