The four-year update gap signals a maintenance-only posture, limiting its ability to compete with modern, actively updated photography tools. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is distributed as a free utility with no observable monetization or in-app purchases. ## SWOT Analysis {#swot} **Core Strengths:** - Open-source distribution establishes developer credibility and transparency within the photography community. - Single-screen interface reduces cognitive load during field-based photography sessions. **Growth Levers:** - Transition to a community-led maintenance model to preserve the utility for the photography community. ## What's New - **Latest (v3.1.1, 4 years ago):** Resolved dark mode display issues and increased minimum iOS requirement to version 12. ## App Momentum (Zombie) {#momentum} - Quiet 4 years, maintenance mode only. - Last major release September 2022. > **Cadence:** 1 total versions · 0 majors in last 6 months · 1472 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Field Tools is a photo & video app that is completely free. It holds a 4.89/5 rating from 9 reviews. > **Bottom Line:** Field Tools provides a reliable, zero-cost utility, but the four-year development hiatus limits its long-term viability against actively maintained rivals. Transitioning to a community-led maintenance model would address the obsolescence risk and preserve the utility for its user base. **Best for:** Photographers requiring quick, field-based depth of field calculations for specific camera and lens setups. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Open-source the maintenance roadmap because the four-year update gap signals a zombie status → prevent total obsolescence ### Outlook: Stable The photography utility market is consolidating around tools that offer cloud-sync and frequent feature updates. Field Tools remains stable as a legacy utility, but its lack of development activity leaves it exposed to OS-level changes that could break the core calculation engine. - ⚪ The four-year update gap indicates a maintenance-only posture, which limits the app's ability to capture new users in a competitive market. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.89/5 | | Total Reviews | 9 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Field Tools** (this app) | 4.89/5 | N/A | Brad Sokol | | [AI Catch: AI Video Generator](https://marlvel.ai/apps/com-prominent-aicatch) | 4.4/5 | n/a | Prominent Fortune PTE.
