The app "Amblyopia – Lazy Eye" is designed to aid individuals in improving visual acuity for amblyopia, commonly known as "lazy eye." It serves as an affordable and accessible alternative to traditional, costly vision therapy that often demands multiple clinic visits. The app targets both children and adults with evidence-based exercises that engage and train the weaker eye through interactive tasks. Key features include customizable settings and progress tracking to monitor user improvement over time. The app operates primarily on a paid download model, with potential for in-app purchases or subscriptions (current setup should be verified). It requires iOS 12.0 or later and has been available since October 2019. The business has shown stable revenue, with a total of $21,167 in earnings. Over the past year, it generated $1,592, averaging $133 monthly, with the highest revenue of $219 in July 2025 and the lowest at $40 in June 2026. There is significant growth potential, as the app's listing is not fully optimized for keywords such as "vision therapy" and "amblyopia treatment." Implementing a subscription model and launching targeted advertising could dramatically increase revenue. New features like AI-based progress analysis and integration with Apple Health, along with localization for non-English-speaking markets, could enhance user retention and expansion. The original developer is selling due to a shift in project focus and believes a new owner with marketing skills can maximize its potential. The sale includes full source code, branding materials, revenue data, and 30 days of support during the transition.
