Gummicube helped Sleepiest boost organic downloads and increase overall conversion by more than 25% in just the first 90 days


Overall Growth










Sleepiest is an app that brings bedtime stories, lullabies, meditations and soothing sounds to millions of users worldwide. An internationally recognized Apple recommendation, Sleepiest hopes to bring its tested sleep aids to users.

Sleepiest is consistently featured by Apple on its today tab giving it widespread visibility. While this is excellent exposure, the Sleepiest team also understood that there was great potential to grow even more by optimizing for organic search. Gummicube was enlisted to help with these efforts.


As part of the optimization process, Gummicube dove into Sleepiest’s historical keyword rankings, external marketing efforts and related apps in its market to gain a deeper understanding of Sleepiest and its targeted audience.

After further research with Gummicube’s App Store Intelligence platform DATACUBE, we were able to understand which keywords to include to help expand Sleepiest’s keyword visibility, aligning with current search demand and popular features. Gummicube was able to identify multiple terms that had an audience overlap. Sleepiest’s main audio aids allow users to fall asleep naturally, while also including multiple meditations, helping them to feel healthier and well-rested.

Gummicube recognized multiple combinations of keywords that Sleepiest could break into tied to these genres, allowing for wider visibility:

  • Help
  • Sleep
  • Sleeping
  • Relaxation
  • Sounds
  • Music/Melodies
  • Mediation
  • Mindfulness

Metadata Deployment Results

Gummicube’s strategy was to target two different markets that best overlapped with Sleepiest’s features. Gummicube applied these insights within Sleepiest’s title, subtitle, keyword bank and description.

This resulted in an increase of high volume, high ranked keywords including several previously unranked terms:

Though Sleepiest was consistently featured in the App Store, App Store Optimization was able to help the app newly rank for relevant high volume terms in the App Store. After just 90 days, Gummicube was able to help Sleepiest achieve over 95% growth in keyword visibility, resulting in a 13.5% increase in organic impressions.

After thorough research of the health and meditation markets, Gummicube created updated screenshots that adhered to creative best practices such as:
