Case Study: Sleepiest boosts App Store visibility and conversion with Gummicube

Sleepiest - Customer Case Study

Sleepiest, a scientifically researched sleep app from Sleepiest Ltd, wanted to improve its organic visibility and conversion in the App Store. Gummicube partnered with the team to strengthen its App Store Optimization (ASO) strategy using its DATACUBE intelligence platform, focusing on keyword growth and better alignment with user search demand.

Gummicube optimized Sleepiest’s metadata across the title, subtitle, keyword bank, and description, then refreshed screenshots through split testing to improve conversion. The result was strong 90-day growth: keyword growth increased 95%, impressions rose 13%, app units grew 26%, and conversion improved 24%, with several key terms newly ranking in top positions such as “fall asleep music” at #1 and “help sleep” at #2.
