Whisperr vs Adapty
Adapty and Whisperr do different jobs. Adapty is subscription infrastructure for mobile apps: purchases, paywalls and A/B tests, revenue analytics and store offers. Whisperr reads subscription events, including Adapty's, plus your product events, decides which users need a retention message, writes it, and sends it by push or email through your own providers.

What Adapty does well
Adapty handles the money side of a subscription app. It validates purchases, keeps one subscription state across platforms, and gives revenue, cohort and lifetime value analytics, including predicted revenue for cohorts. Its no-code paywall builder uses native components and ships without an app release, and its A/B tests compare paywalls, prices, trials and onboarding by revenue. It manages promotional and win-back offers from the stores and can act as the backend for Apple’s retention messages shown on the iOS cancel screen.
How Whisperr works differently
Adapty tells you who subscribed, renewed or cancelled. Whisperr acts on each user before that happens. It reads product events from your app and subscription events from Adapty, decides for each user whether a message would help, writes it for that user in your app’s voice and their language, and sends it by push or email through your own providers (OneSignal, Firebase Cloud Messaging, Apple Push, Expo, Postmark, Resend or SendGrid).
Built-in subscription moments are a trial about to end, a failed payment, and a user who turned off auto-renew but still has access. A 10% holdout shows how many users the messages kept, once each group has 200 users.
Which should you choose?
They fit together rather than compete:
- Adapty runs purchases, paywalls and revenue analytics.
- Whisperr runs the retention messages that keep subscribers paying.
If you already use Adapty, connect it to Whisperr and your subscription events start informing who gets a message.
