# Whisperr vs Airship

Airship is a mobile-first engagement platform: your team builds journeys across push, SMS, email, in-app and mobile wallet, with predictive churn and optimal send time built in. Whisperr decides for each user whether a retention message would help, writes it, and sends it by push or email through your own providers. Choose Airship for enterprise multichannel programmes; choose Whisperr to have subscription retention run without building them.

## What Airship does well

Airship has deep roots in mobile push and a wide channel set, including mobile wallet passes. Its journeys combine sequences, in-app Scenes and automations, its Predictive Churn tags users by risk of going inactive, and Optimal Send Time picks the best hour per user from their app opens. Holdout Experiments exclude a random group from all messages so you can measure the effect. For large brands with mobile marketing teams, it's a complete toolkit.

## How Whisperr works differently

Airship's tools help your team decide and build. Whisperr does the deciding and writing for retention. For each user, it reads their product events and their subscription events from RevenueCat, Superwall or Adapty, and decides whether a message would help. When it would, Whisperr writes that message for that user and sends it through your own push or email account. Users who are doing fine get nothing.

New apps start in approval mode, so you approve each message until you trust it. Caps, cooldowns and quiet hours in the user's local time keep the volume down.

## Which should you choose?

**Choose Airship if** you're a larger brand with a mobile marketing team, need SMS, wallet or web channels, and want one platform for every kind of campaign.

**Choose Whisperr if** you run a subscription app, retention is the job, and you want it decided and written per user, sent through your own providers, with public pricing.

## FAQ

### How much does Airship cost compared with Whisperr?

Airship doesn't publish prices. Its Experience Platform is priced by quote, and Airship Essentials is a self-service tier without a listed price. Whisperr is free up to 1,000 users and its paid plans start at $49 a month, each with a 30-day free trial.

### What does Airship's Predictive Churn predict?

It tags active users as high, medium or low risk of churning, where churned means no app opens, web visits or web notification clicks for 30 days. That's inactivity, which is related to but not the same as a subscription cancel.

### Do both measure lift with a holdout?

Yes. Airship's Holdout Experiments exclude a random group from all messages and report goal performance for the holdout and treatment groups. Whisperr holds back 10% of users by default and shows the difference in retention and revenue kept with a 95% confidence interval, once each group has 200 users.

### Can Whisperr use subscription events like Airship does with RevenueCat?

Yes. RevenueCat can send subscription events to Airship to trigger journeys you build. Whisperr reads subscription events from RevenueCat, Superwall or Adapty and covers trial-ending, failed-payment and renewal-off moments itself.
