Repro Inc., which supports maximizing web and app revenue by providing marketing solutions, has announced the results of the implementation of "Repro App," a package for maximizing app sales and LTV, part of its multi-channel integrated marketing automation "Repro MA," for the short drama app "BUMP" operated by emole Inc. The case study, including an interview, has been made public.
The short drama app "BUMP," developed by emole Inc. with the vision "To a world where creation can be challenged," offers the great appeal of enjoying short dramas of 1 to 3 minutes per episode during free moments, allowing users to immediately watch works they found interesting on social media. However, it also faced the challenge of users often leaving after watching only a specific work, which made it difficult to encourage overall app navigation and continuous use.
Therefore, the company introduced Repro App with the goal of improving the "7-day completion rate" (the percentage of users who complete one work, meaning watch all episodes, within one week) and began improvements based on user behavior data.
This time, they are announcing their achievements as a case study.
Preventing "leaving after watching one work" and improving the 7-day completion rate. A unique development process also established.
While BUMP was successful in attracting new users continuously through SNS, they believed there was still room to improve the retention rate. To achieve this, they prioritized delivering the experience of "watching a short drama to the very end" to users. They set the 7-day completion rate, which indicates the percentage of users who watched all episodes of one work within one week of starting to use the app, as a metric to measure the quality of the experience.
To improve the 7-day completion rate, they felt the necessity to quickly cycle through improvements, even with non-engineer operational staff. They introduced "Repro App," the app sales and LTV maximization package of "Repro MA," which is equipped with the necessary functions to quickly deliver, review, and improve push notifications and in-app messages (pop-ups). The post-introduction support system, which allowed them to consult on prioritizing measures and specific setup methods, was also a major deciding factor.
Actual push notifications (left) and in-app messages (right) sent. Push notifications effectively guided users to app viewing by incorporating trending scenes and phrases, making them think, "Oh, this was the drama I saw on SNS." In-app messages with finely tuned targets had a high CTR, showing a positive change in the 7-day completion rate.
After introducing Repro App, they began improvements based on user behavior data. Through repeated quick verifications utilizing push notification and pop-up functions, and designing optimized user flows and appeals for each user, they achieved their target 7-day completion rate improvement. Furthermore, they established a unique development process: verifying measures with Repro App before full-scale feature development and only implementing those with tangible results.
Evaluation of Repro App
Regarding Repro App, Mr. Yuki Sasaki, PdM of Product Div., emole Inc. (responsible for BUMP), and Ms. Ayano Date, Product Div. (responsible for operations), have provided the following comments:
-- Comments from Mr. Yuki Sasaki --
By utilizing Repro App not merely as a delivery tool but also as a verification platform, there has been a change in how we proceed with product development and our decision-making process.
Engineer resources are finite, so embarking on heavy feature development with insufficient hypotheses and releasing without knowing if it will "hit or miss" is a big risk for a product. Before full-scale implementation, we now first use Repro App to directly ascertain user reactions. Only those measures that show tangible results in terms of numbers are then placed on the product roadmap. In other words, Repro App is used as a verification platform to pre-emptively increase the probability of success before full implementation. This established flow has eliminated the anxiety of allocating resources to uncertain endeavors, allowing the entire team to pour all their energy into measures with the conviction that "we can win."
-- Comments from Ms. Ayano Date --
We can now complete processes that previously required engineers on our own, and the speed of push notification operations has visibly improved. Verifications utilizing in-app message (pop-up display) functions can also be performed with small-scale hypothesis testing led by the team on the ground.
By optimizing who, when, and what to communicate, we have gained a tangible sense of delivering the value of previously buried works to users and connecting it to changes in behavior.
