The absence of updates since May 2022 suggests the product is in maintenance mode rather than active market competition. ## Monetization Strategy - **Model:** Free - **Tiers:** Fully free utility - **Analysis:** The app operates as a free utility with no visible monetization, subscription, or ad-based revenue model. ## SWOT Analysis {#swot} **Core Strengths:** - Custom circle of confusion calculation provides precision for technical photographers **Growth Levers:** - Modernizing sensor format presets could attract users from manual calculation workflows ## Recent Changes (v2 → v3) {#recent-changes} The outlook for the utility has shifted from stable to declining, as the 1,564-day development gap now presents a critical risk of platform-level deprecation. The analysis identifies the lack of a revenue model as the primary barrier to the maintenance required for long-term viability. **Overall trend**: Declining **Compared at**: 2026-08-28 ### High-impact changes - **[Shifted] Outlook Trend** (positioning) ### Medium-impact changes - **[Shifted] Threats and Weaknesses** (swot) ## What's New - **Latest (v1.1.2, 4 years ago):** Optimized hyperfocal distance button visibility and fixed display errors in the Circle of Confusion pane. ## App Momentum (Zombie) {#momentum} - No updates for over 1500 days. - Maintenance-mode status confirmed. > **Cadence:** 1 total versions · 0 majors in last 6 months · 1563 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Depth of Field Estimator is a photo & video app that is completely free. It holds a 4.86/5 rating from 65 reviews. > **Bottom Line:** Depth of Field Estimator provides a stable, specialized utility for optical calculations, but the four-year development silence leaves it exposed to platform-level deprecation risks that would force users toward active alternatives. **Best for:** Photographers requiring precise optical calculations for depth of field and focus range estimation. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit codebase for iOS compatibility because the last update occurred in May 2022 → prevent potential launch failures ### Outlook: Declining The market for specialized photography utilities is consolidating around apps that integrate directly with camera-control workflows rather than standalone calculators. Depth of Field Estimator remains exposed to platform-level changes, and the lack of a revenue model suggests no path to the active development required to defend its niche. - 🔴 The 1564-day update gap signals that Depth of Field Estimator is in maintenance mode, which increases the risk of sudden churn due to OS incompatibility. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.86/5 | | Total Reviews | 65 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Depth of Field Estimator** (this app) | 4.86/5 | N/A | Malte Jan Michael Gurgel | | [Cantina: AI Video & Characters](https://marlvel.ai/apps/is-signal-ios) | 4.8/5 | N/A | Cantina, Inc | | [CapCut: Photo & Video Editor](https://marlvel.ai/apps/capcut-photo-video-editor) | 4.1/5 | Mixed | Bytedance Pte.
