Project Summary

Young Decade developed native iOS and Android apps for an earbud-replacement marketplace, performing product discovery, UI/UX design, API redesign, and DevOps setup. Post-launch metrics included 18,400 downloads in the first 30 days, an increase in in-app checkout completion from 38% to 71%, a 2.6× rise in monthly GMV within 90 days, and a Day-30 retention of 43%. The team also delivered strong technical KPIs, including a 1.2-second average cold-start time on iPhone 12 and zero ANRs on Android.

Key Challenges

  • Mobile traffic had stagnated and required improvement
  • Client lacked in-house mobile expertise
  • Tight budget constraints
  • Strict launch deadline coinciding with an upcoming iOS release

Project Deliverables

  • Design system in Figma
  • Native iOS and Android apps (SwiftUI, Kotlin)
  • GraphQL backend layer
  • DevOps and release pipelines (Fastlane, TestFlight, staged rollout)
  • Analytics integrations (Firebase, Amplitude, RevenueCat)
  • Knowledge transfer and documentation (pair programming, Loom walkthroughs)

Project Solution

Young Decade performed end-to-end mobile product work: product discovery with user interviews, UX sprints and a Figma design system, native development for iOS (SwiftUI) and Android (Kotlin), API redesign into a GraphQL layer, DevOps and staged releases (TestFlight, Fastlane), analytics integration (Firebase, Amplitude, RevenueCat), and knowledge transfer via pair programming and recorded walkthroughs.

Project Outcome

  • 18,400 downloads in the first 30 days (target was 10,000)
  • In-app checkout completion rose to 71% from 38%
  • Monthly GMV increased by 2.6× within 90 days
  • Sales covered development costs within six weeks
  • Day-30 retention improved to 43% (from 19% on mobile web)
  • 4.9/5 App Store rating based on 1,200 reviews
  • Technical KPIs: no Android ANRs for 60 days; 1.2s average cold-start on iPhone 12
