Without a fix for the connectivity regressions, the app will continue to lose its remaining user base to the official manufacturer software or other third-party tools. - 🔴 The 27-month development silence → total loss of connectivity → permanent user churn as photographers switch to more reliable alternatives. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.33/5 | | Total Reviews | 43 | | Sentiment | Frustrated (35/100) | | Confidence | High | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **GRImageViewer** (this app) | 3.33/5 | Frustrated | Pin Chih Lin | | [AI Catch: AI Video Generator](https://marlvel.ai/apps/com-prominent-aicatch) | 4.5/5 | n/a | Prominent Fortune PTE.
