The lack of updates for 2,500 days indicates the app is a legacy utility rather than a growth-focused product. ## Monetization Strategy - **Model:** Free - **Tiers:** Completely free utility with no in-app purchases - **Analysis:** The app operates as a free utility to build brand recognition for the developer's paid professional cinematography software. ## 🟢 User Sentiment (Medium Confidence: 2 of 2 reviews analyzed) {#user-sentiment} - **Overall Rating:** 4.44/5 - **Platform Split:** iOS 4.4/5 (9 ratings) - **Overall Sentiment:** Thrilled ### Top Praises - **The back focus chart provides professional utility without the high cost of competing industry tools** - **The application design remains simple and focused, avoiding unnecessary features that clutter the user experience** ## SWOT Analysis {#swot} **Core Strengths:** - Siemens Star graphic provides a professional-grade calibration standard - Display wake-lock ensures reliability during extended calibration sessions **Growth Levers:** - Modernizing the display wake-lock for current OS standards - Cross-promoting the developer's paid cinematography suite to existing users ## What's New - **Latest (v2.0, 6 years ago):** Implemented layout optimizations. ## App Momentum (Zombie) {#momentum} - No feature updates for 2,500 days. - Maintenance-only status for six years. > **Cadence:** 1 total versions · 0 majors in last 6 months · 2500 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Focus Chart is a photo & video app that is completely free. It holds a 4.44/5 rating from 9 reviews. > **Bottom Line:** Focus Chart remains a reliable, specialized utility, but the six-year development gap signals that it is a legacy brand-anchor rather than an active product. A technical audit of the wake-lock functionality would ensure the tool remains viable for its professional user base. **Best for:** Cinematographers, photographers, and camera assistants requiring a portable tool for lens calibration. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit display wake-lock compatibility because the app has not been updated in 2,500 days → ensure core utility remains functional ### Outlook: Stable The professional cinematography utility market is stable, but Focus Chart's long-term inactivity leaves it vulnerable to technical obsolescence. The PM should prioritize a basic compatibility audit to ensure the tool continues to serve its purpose as a brand-authority anchor for the developer's broader software suite. - ⚪ The 2,500-day update gap indicates the app is in maintenance mode, which limits growth but preserves the core utility for existing users. - 🔴 The lack of recent development leaves the app exposed to future OS-level display changes that could break the core wake-lock functionality. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.44/5 | | Total Reviews | 9 | | Sentiment | Thrilled (90/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Focus Chart** (this app) | 4.44/5 | Thrilled | Cadrage GmbH | | [AI Catch: AI Video Generator](https://marlvel.ai/apps/com-prominent-aicatch) | 4.4/5 | n/a | Prominent Fortune PTE.
