# Whisperr vs CleverTap

CleverTap is an analytics and engagement platform: your team builds journeys and campaigns across push, email, WhatsApp, in-app and SMS, with predictions and a control group built in. Whisperr is narrower: it decides for each user whether a retention message would help, writes it, and sends it by push or email through your own providers. Choose CleverTap for analytics plus many channels; choose Whisperr to have retention run without building journeys.

## What CleverTap does well

CleverTap puts product analytics and engagement in one place, so the team that reads the funnel can act on it in the same tool. It covers a wide set of channels, including WhatsApp and RCS. Its Predictions create system predictions such as retention and uninstalls, IntelliTime picks per-user send times on higher plans, and the System Control Group keeps a share of users out of every campaign so you can see the effect. The Core plan has a listed price and a 30-day trial.

## How Whisperr works differently

CleverTap gives your team the tools. Whisperr does the work those tools are used for in retention. It reads each user's product events and subscription events from RevenueCat, Superwall or Adapty, decides whether a message would help, writes that message for that user, and sends it through your own push or email account. There are no journeys or segments to maintain, and users who are doing fine get nothing.

New apps start in approval mode, so you approve each message until you trust it. A 10% holdout shows how many users the messages kept, once each group has 200 users.

## Which should you choose?

**Choose CleverTap if** you want analytics and engagement in one platform, need channels like WhatsApp or SMS, and have a team to build and run journeys.

**Choose Whisperr if** your analytics already live elsewhere, you want retention decided and written per user without building journeys, and you want to keep your own push and email providers.
