Case Study: Hallow achieves 2M+ app installs and #1 App Store ranking with Branch

How Hallow Drove Over 2 Million App Installs and Became #1 on the App Store

Hallow, the Christian prayer and meditation app, needed a better way to manage deep links, peer-to-peer sharing, and web-to-app conversion across organic and paid channels. After moving from AppsFlyer to Branch, Hallow used Branch tools like sharing links, Journeys, and Universal Ads to make user journeys more seamless and trackable.

Branch helped Hallow optimize campaigns, A/B test banners, attribute influencer and QR code traffic, and improve ROI during Lent. The results were strong: Hallow reached #1 on the App Store, drove over 2 million installs in February alone, saw 50% of installs and 43% of subscriptions attributed to Branch, reduced CAC by 42%, increased trial conversion 2.2x month over month, and improved retention by 26% year over year.
