Violin Lessons by tonestro – app for learning how to play the violin with high-quality, step-by-step lessons, real-time feedback technology and a vast sheet music library.

Apart from advanced, high-quality options for learning violin, the app has one more important feature – violin tuner. It helps users easily tune their violin with precision and accuracy. Violin tuner keywords have good Search Popularity and therefore are capable of getting higher impressions volume and engaging more users. However, default product page screenshots are focused on violin learning features and do not highlight violin tuner to the full extent. As a result, potential violin tuner users may not be engaged.

SpliMetrics Agency experts aimed to increase user engagement and drive conversions for the violin tuner feature. Aligning with our Client’s vision, we also aimed to improve overall user satisfaction and retention by making the feature more accessible. Thus keeping users in the violin learning loop and preventing frustration and progress hindrance by playing an out-of-tune.

To achieve the above mentioned objectives by building a custom product page that resonates with potential users, SplitMetrics worked closely with the Client who provided insights on what is important for violin students. With this knowledge, SplitMetrics experts designed, developed and launched a custom product page for the violin tuner in Apple Search Ads. This custom product page offered an in-depth look at the feature and its benefits, making it easier for users to understand the value and reinforce their commitment to learning violin.

We expected growth in volume and conversion rates with the increased relevance to the audience who came with a specific search for violin tuner.
