Churn is more than just a number; it’s a barometer for the health of your subscription business. Whether it’s voluntary churn, where users actively decide to leave, or involuntary churn caused by payment failures, the implications are the same. Churn can eat into your profits, reduce long-term customer value, and hinder growth.

This blog will guide you through the many early signals that indicate that churn is on the way.

Early warning signs of churn (and how you can respond)

Reduced app engagement

There is no substitute for keeping a close eye on app usage metrics to monitor engagement. Here’s what to look out for:

  1. Frequency of usage: Monitor how often users open your app. A decline suggests decreasing interest. Keep an eye on both short-term and long-term trends.
  2. Session length: Pay attention to how long users engage. Shorter sessions may indicate waning interest.
  3. Feature engagement: Keep track of which app features are popular. A drop in use can be a warning. Consider offering guides or tutorials for underutilized features.

Remember that reduced engagement with a feature might indicate changing needs, not dissatisfaction. For instance, a user might stop using a period-tracking app during pregnancy or a fitness app after New Year’s resolutions fade. The response and messaging to prevent churn vary for each situation. While preventing churn isn’t always possible, like with the period-tracking app, you can aim to re-engage users at the appropriate time.

Later, I’ll discuss categorizing users based on predicted outcomes, like subscribing or churning. For now, let’s touch on the “habit path” from Nir Eyal’s “Hooked”. Identify and map out the journey of your habitual users. For example, early on, Twitter found users who followed a certain number of accounts became regulars. Examine your app’s feature engagement and identify its habit path. Preventing churn often means converting users into habitual ones.

What do you do once you’ve noticed a decline in engagement?

Once you notice these reduced engagement, it’s time to take action. Personalized in-app messages or push notifications can remind users about the value your app provides. Special offers or loyalty rewards can also incentivize users to re-engage with your app.

In this blog, I’ll discuss how customer relationship management (CRM) can engage users to prevent churn. For more, see our guide on CRM optimization for subscription apps.

Negative user feedback

Direct complaints: Monitor customer support tickets for any increase in complaints or issues.

Poor app store reviews: Users often express dissatisfaction through app store reviews before churning, so watch out for patterns in low ratings and critical comments. Monitor these yourself or use one of a variety of tools to automate tracking such as Appfigures or App Radar.   

Many app businesses don’t take customer support seriously enough. For Talking Parents CEO Vince Mayfield, charging for a premium subscription means that you should be offering premium support.

“Every experience that somebody has with your brand sets a mental image of who you are. And so, if I’m gonna charge a premium price, then they need to have premium support… We go in and reply to every app review with a human response… It’s about radical focus on the customer. If they feel like they’re heard and that we’re listening to them, they’re gonna continue to stay on a subscription with us, and we’re gonna have great retention rates.”

Vince Mayfield, Talking Parents

There’s an interesting story on the Sub Club community in which a developer turned a 1-star review “Worst App Ever!” into a 5-star review. The first step was taking on board the feedback. The second step was responding in a thoughtful way. 

Sentiment tracking: Use online, in-app or email surveys, to gauge the satisfaction of your users. While you can look to gain detailed feedback, for sentiment tracking over time, you might prefer to ask a question like “How likely would you be to recommend [your app] to a friend or colleague?”, with an accompanying score of 1-10, to allow you to record a Net Promoter Score (NPS).

Tracking NPS scores is an important tool for your app growth in general (this Phiture article by Alice Muir is a great resource). But from the context of churn detection, monitor your NPS over time. A decline can indicate a problem. And with CRM, you can trigger campaigns targeting detractors (i.e. those users that would rate your app from 0-6) to attempt to turn their negative experience around. 

Billing and payment issues

Failed payments and involuntary churn: Involuntary churn, often caused by failed payments due to expired or changed credit card details, or new devices, poses a significant problem that frequently goes unchallenged by many apps. 

While both Apple and Google have implemented measures to address this, it is vital to actively manage this issue rather than solely relying on the app stores’ mechanisms. You should complement them with proactive measures such as real-time notifications for payment failures. Use the information provided in real time by Apple and Google to trigger automated emails or push notifications to your customers, encouraging them to update their payment details. And remember that grace periods on iOS and Android need enabling — they will not be turned on by default. 

For web payments, you have a greater challenge. Not only will you need to handle most of the communications yourself, you rely on the user coming back to update their details for your app, specifically. Generally speaking, users are more likely to keep their details up-to-date on the app stores, given that so many other services and apps depend on them. 

Downgrades: Keep an eye out for users who downgrade their subscriptions or remove add-ons. These actions can be a sign of customers contemplating cancellation. Proactively reaching out to these users with tailored communications and offers may help sway them back or at least provide insight into their concerns.

Using predictive modeling to anticipate churn 

Predictive analytics, or modeling, harnesses data to forecast user actions like subscribing, renewing, or churning. Such correlation analysis — which pinpoints behaviors linked to specific outcomes — is common among data-rich app companies. These insights are either extracted via analytics tools, like Amplitude or Mixpanel, or through data analysts utilizing data warehouses. Note: Amplitude suggests a base of “over 100,000 monthly average users” for accurate predictions.

“We analyze key events that are part of the core functionality. And we pull together what is essentially a correlation analysis. You would say: how likely is it that completing x meditation pack, for example, correlates with somebody becoming a premium subscriber.”

Alice Muir, Phiture, on the Sub Club podcast

Using this analysis, you can pinpoint users veering towards churn or away from renewal. The next step? Employ CRM to guide them back on track.

Can newer apps with limited data adopt this method?

Despite potential data or team constraints, early-stage apps can still categorize users based on behavior. Alice Muir suggests that sometimes results can be intuitive; for instance, users completing a non-essential registration might be ripe for upselling. To predict and counteract churn, identify high-intent behaviors in your app and remain alert to low-intent ones. The latter (e.g., a user bypassing a vital feature) indicates where targeted messaging becomes crucial.

Use churn to prevent churn 

When a user churns, use that as an opportunity for learning.

In its early days, photo-editing app PhotoRoom only launched with a monthly plan, foregoing an annual plan, so they could get users churning sooner. With annual plans, while they’re great for cashflow, it’s going to take a long time before you know if your app is delivering enough value for users to renew. With monthly, you can make use of each churn event to gain feedback from your users much more quickly. You can do this by asking users to fill out a feedback survey — a good example of this is what Rise sends out to users who have turned off auto-renew.

“We actually put forth first a monthly plan because we wanted people to churn and be able to talk to them. So there was really a focus on learning from the early days.”

Matthieu Rouif, PhotoRoom

Other signs and tips

Here are some extra considerations and ideas that don’t fit neatly into other sections:

  • Find out the renewal intent of your users on annual plans sooner rather than later. Don’t wait until the very end of their subscription or for the automatic renewal emails from Apple and Google. Get your renewal comms earlier than this and find out which users are more interested in renewing — and if they’re showing signs that they’re not, this gives you more time to do something about it. 
  • For apps at a very early stage: Have the “willingness to pay conversation” early. Even if your app serves a need and provides value, that’s no guarantee that users will pay beyond a trial or at the cost you’re charging. Having confidence in both your pricing and your product will mean you can have greater confidence that fewer users will eventually churn.

How RevenueCat can help 

There are two areas where RevenueCat can help: what you can see within the RevenueCat dashboard itself, and what data you can send to other tools with our integrations or to a custom data warehouse with Scheduled Data Exports

In the dashboard, when viewing the Subscription Retention chart, the dashed line indicates an incomplete period where the cohort hasn’t matured (i.e. the users haven’t reached their renewal date). If this dashed line is lower than the complete period, this shows you how many of the cohort have turned off auto-renew. This can be particularly useful for spotting early churn signals for annual subscriptions as you’ve got a longer time-frame to work with. 


When it comes to delving deeper into user behavior, RevenueCat directly integrates with analytics tools such as Amplitude and Mixpanel, layering that rich source of subscription lifecycle data that RevenueCat provides. If you’re using a custom analytics tool, you can send your subscriber data to a variety of cloud storage providers.

And when you’re ready to trigger win-back campaigns on those users, you can integrate with tools such as Braze and Intercom. We have a whole blog on creative campaign ideas for winning back users who have turned off auto-renew that you can explore. 

Pre-empting churn: Your next steps

  1. Dive deep into metrics: Revisit your app usage metrics. If you haven’t already, set up dashboards to closely track frequency of usage, session length, and feature engagement. Tools like Amplitude or Mixpanel can be a great starting point.
  2. Engage with users: Actively engage with your users through feedback. Consider setting up automated surveys after specific actions or in-app feedback buttons. The feedback you receive will be invaluable.
  3. Revise your CRM strategy: If you’ve not yet incorporated a customer relationship management (CRM) tool, now is the time. Use it to communicate, engage, and re-engage with users, especially those showing signs of reduced engagement.
  4. Anticipate payment issues: Streamline your payment systems. Consider automated reminders for upcoming payment renewals or card expirations.
  5. Experiment with predictive analytics: Even if you’re an early-stage app, start small by grouping users based on behavior and use this data to anticipate possible churn.
  6. Learn from churn: As painful as it is when a user churns, use it as an opportunity. Establish a system to get feedback from users who cancel their subscriptions.
  7. Stay updated: We regularly create and curate resources to help you manage churn, so subscribe to the Sub Club newsletter to stay up-to-date.
