Without a shift to a more frequent update cadence, the app risks losing functionality as Safari's browser architecture evolves. - ⚪ The lack of feature updates for over 100 days indicates a maintenance-only posture, which limits the app's ability to adapt to new Safari API changes. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Web Overlay Canvas for Safari** (this app) | N/A/5 | N/A | Yoshitaka Nishishita | | [HitWave](https://marlvel.ai/apps/ciendor-applications-hitwave) | 2.5/5 | Mixed | Ciendor Holdings Corp.
