The Challenge
Legacy Scrapbook came to TechArk with a mobile app that had been poorly coded and configured. Core APIs for account creation, email communication, and user management were broken, making the platform unreliable. The app was not optimized for scalability, and essential security features were missing. Without stability or proper subscription handling, the client couldn’t grow or confidently offer the service to paying users.
The Solution
TechArk first stabilized the legacy app by reconfiguring broken APIs, fixing code quality issues, and successfully publishing it to the App Store and Play Store. Once the foundation was in place, we delivered improvements in two major phases.
– Phase I introduced monetization and premium features. We integrated native in-app billing for Google Play and Apple Store, implemented a 7-day trial, subscription tiers ($10 basic and $15 premium with secure vaults), and advanced error handling. Users could now unlock secure folders, manage sensitive credentials, and subscribe seamlessly, giving the app a sustainable revenue model.
– Phase II focused on rebuilding critical infrastructure: a secure admin dashboard, user management, attachment categorization, phone number–based login with two-factor authentication, legacy user invitations, and SendGrid email integration. These changes made the app secure, organized, and scalable.
Performance Snapshot
- 81 hours invested in Phase I to rebuild core infrastructure and stabilize the app
- 200+ development hours in Phase II to deliver secure subscription handling across iOS, Android, and APIs
- Enhanced user security with phone-based two-factor authentication
- Seamless subscription model enabling free trials, tiered plans, and secure vault features
The Results
- Stabilized app with properly configured APIs and secure infrastructure
- Successfully published on both iOS and Android, restoring client confidence
- Created a path to recurring revenue through tiered subscription features
- Positioned Legacy Scrapbook for long-term growth with a scalable, future-ready platform
