A Workout App Increased Reminder Campaign CVR by 29% with Continuous A/B Tests

Company

There is a dynamic workout app designed for fitness enthusiasts aiming to improve their health and well-being. Essentially, it is a virtual personal trainer that tailors fitness plans to the individual needs of users exercising at home or in the gym.

With a focus on diverse fitness goals, such as muscle building and fat-burning cardio, the app leverages an AI-driven training algorithm to create personalized workout strategies based on individual user objectives, body measurements, and available equipment. Users are guided through sets, rep ranges, and rest intervals to ensure they effectively progress toward their goals.

Key features of the app include:

• A comprehensive library of over 1,000 targeted workouts.
• Audio-guided Workout Player offering exercise instructions and muscle usage insights, compatible with Apple Watch.
• Specialized fitness challenges tailored to user onboarding, covering routines such as fat burning and injury recovery.
• Personalized workout plans that factor in available equipment, estimated completion time, and metabolic rate.
• Muscle recovery guidance and milestones for non-stop motivation.

This H&F app operates on a freemium monetization model. The app is free to download, providing basic access to its features, while full functionality requires a paid subscription. Payments come with auto-renewal options that can be managed through the App Store, ensuring seamless access to premium content. Activated plans unlock the full workout library, personalized workouts, and advanced features like the AI-powered fitness test and detailed muscle recovery insights.

Challenge

With a growing user base relying on timely, motivational push notifications to stay on track - whether for morning routines, gym sessions, or recovery workouts - the app needed a solution to effectively scale its reminder campaigns.

Previously, the company relied on traditional A/B testing techniques to ensure ongoing user communication. This time, however, their team was looking for a proven, scalable way to optimize the messaging flows of their push campaigns in a cost-neutral, resource-friendly way.

The key challenges included:

• Streamlining the A/B testing process without disrupting existing workflows.
• Enhancing the impact of reminder campaigns to increase user engagement and retention. 
• Ensuring continuous campaign optimization that requires minimal manual effort.

The stakes were high, as inefficient testing could lead to stagnant user retention, increased churn, and missed recurring revenue opportunities.

Solution

To scale their reminder campaigns, the product’s marketing team partnered with Reteno and adopted its “One from many” messaging block. This game-changing tool changed the way they built and optimized regular push notifications. The app’s team was able to seamlessly design messaging workflows that tested multiple reminder variations in a single, automated process.

With Reteno’s innovative messaging optimization solution, the following benefits have been achieved:

1. Swift multi-variant testing. Marketers could experiment with multiple reminder versions in real time. This allowed them to effortlessly tweak elements such as copy, tone, and calls-to-action. The need for separate, time-consuming A/B testing for each push notification was eliminated.
2. Automated high-performer selection. The system evaluated engagement metrics, such as click-through rate (CTR), to automatically identify the top-performing reminder and deliver it to the broader audience. This ensured that fitness fans received the most impactful nudges without delay.
3. Seamless reminder campaign flow optimization. By integrating Reteno’s state-of-the-art A/B testing into the message flow, the health & fitness app aligned each nudge with the user’s fitness journey, improving the overall experience from initial prompt to workout completion.
4. Resource efficiency. The automated, easy-to-maintain campaign creation and testing process slashed manual effort. As a result, marketing and product teams were freed from repetitive testing tasks, allowing them to prioritize strategic initiatives.

Results

Armed with Reteno’s AI-powered messaging optimization solution, the app’s marketing team achieved a standout result that underscored the power of continuous campaign performance testing. While click-through rates (CTR) showed little change, the real win was a 29% boost in conversion rates (CVR), a key metric directly impacting revenue. This shift meant that fewer app users clicked aimlessly. Instead, the fitness geeks, who did engage, were significantly more likely to take a desired action, namely completing workouts.

For the H&F app, this translated into a direct benefit, as higher conversions signaled stronger user commitment. The marketing team’s focus on message quality and refining reminder flows with Reteno’s scalable A/B testing paid off by prioritizing high-value engagement over sheer click volume.

This strategic pivot improved the user experience and increased subscription revenue opportunities. It also proved that smarter testing, paired with a well-optimized conversion funnel, can deliver outstanding business results even when traditional metrics take a back seat.

The success list includes:

• 29% boost in CVR
• Increased revenue opportunities
• CTR with smarter focus
