DX Pro Skin 2 / DX Pro Hair 2 1. App Description DX Pro Skin 2 / DX Pro Hair 2 DX Pro Skin 2 and DX Pro Hair 2 are the next-generation successors to DX Pro Skin and DX Pro Hair. Due to a fundamental redesign of the underlying database architecture, the new apps are not backward-compatible with the previous versions. Both versions will remain available to ensure uninterrupted service for existing users during the transition period. What's New in Version 2: Reliability — No More Data Loss All diagnostic sessions are saved in real time to a local on-device database. If the app closes unexpectedly or the battery dies, users can resume exactly where they left off. A smart sync engine uploads data to the cloud automatically once connectivity is restored, enabling full offline diagnostics. Speed — Faster Analysis A parallel background processing engine reduces wait time between image capture and AI analysis results. Screen transition latency has been reduced by over 50% (from 200ms to 100ms), delivering a noticeably smoother experience during client sessions. Client History — Cloud-Backed and Portable All diagnostic records, including images and reports, are stored in a standardized cloud format. Reinstalling the app or switching devices does not result in data loss — full client history is restored automatically. Maintainability — Faster Support Structured logging and error tracking allow the support team to diagnose and resolve field issues remotely and more quickly. 2. Review Notes (■■■ ■■■ ■■) Note to App Review Team: This app (DX Pro Skin 2 / DX Pro Hair 2) is a new, standalone application and is not a duplicate of the existing DX Pro Skin / DX Pro Hair apps currently live on the store. The reason both versions coexist is that Version 2 uses a completely redesigned database schema that is not compatible with Version 1 data. A forced migration would result in permanent data loss for existing users. To protect existing users and allow a smooth voluntary transition, we are maintaining both apps simultaneously during the migration period. Version 2 offers the following substantive new functionality not present in Version 1: • Local SQLite-based auto-save with session resume capability• Offline-first diagnostic mode with background cloud sync • Standardized data schema enabling future cross-platform integrations • 50%+ reduction in UI transition latency via parallel async processing • Remote diagnostic logging and error tracking infrastructure We appreciate your understanding and are happy to provide additional technical documentation upon request.
