Manual entry model lacks the automation of competitors like Gloomhaven Scenario Viewer - No multi-device sync or server-side campaign tracking for gaming groups **Growth Levers:** - Integration of image recognition to automate clue tracking from physical game boards - Partnerships with physical board game publishers for official digital companion status **Market Threats:** - Bundled board game apps like Board Games Arena reduce the need for niche utilities - Automated companion apps with fog-of-war mechanics capture higher-intent tabletop users ## Recent Changes (v3 → v4) {#recent-changes} The app's competitive positioning shifted to acknowledge the threat of automated, image-recognition-based companion tools, while the product remains in a maintenance state. **Overall trend**: Stable **Compared at**: 2026-05-25 ### High-impact changes -

**[Yatzy & Farkle: Dice World](https://marlvel.ai/intel-report/games/yatzy-farkle-dice-world)** by AppA11y, Inc.: This app competes for the same casual board game enthusiast demographic by providing a digital utility for classic tabletop mechanics. -

Last major update Dec 2025. > **Cadence:** 1 total versions · 0 majors in last 6 months · 152 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Detective Notes is an established games app that is completely free. With a 4.68/5 rating from 217 reviews, it shows polarized user reception. > **Bottom Line:** Detective Notes holds a strong niche position through customization, but it lacks the automation and group-sync features of modern tabletop companions, so the PM should prioritize multi-device data sharing to prevent churn to more robust campaign trackers. **Best for:** Board game enthusiasts who play deduction-based mystery games and want a digital, paperless alternative to traditional score pads. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [HIGH IMPACT] Ship multi-device sync because the lack of group data sharing is a feature gap against Gloomhaven Campaign Tracker → increase retention — *Competitor analysis shows multi-device sync is a standard differentiator for board game assistants.* _(trade-off: deprioritize Pause the multilingual support expansion to new languages — current 6-language coverage is sufficient for the core market.)_ ### Feature Gaps vs Competitors - Multi-device server sync (available in Gloomhaven Campaign Tracker) - Automated fog of war (available in Gloomhaven Scenario Viewer) - Hardware-based input integration (available in Battle Grid Companion) ### Outlook: Stable The tabletop companion market is shifting toward automated, multi-device integrated tools that handle complex game states for the user. Detective Notes remains stable but exposed to these more feature-rich competitors, so the PM must decide whether to remain a lightweight utility or pivot toward group-sync capabilities to stay relevant. - ⚪ The app maintains a stable rating and update cadence, suggesting a mature product that is not currently pursuing aggressive feature expansion. - 🔴 The emergence of bundled board game apps threatens to consolidate the utility market, which could erode the install velocity of single-purpose tools. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.68/5 | | Total Reviews | 217 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Detective Notes** (this app) | 4.68/5 | N/A | Kyeong Cheon Yang | | [Kingdomino: The Board Game](https://marlvel.ai/intel-report/games/com-meeplecorp-kingdomino) | 4.9/5 | Excited | Meeple Corp | | [Tombola (Italian Bingo)](https://marlvel.ai/intel-report/casino/com-mobilesafeapps-tombola) | 4.5/5 | N/A | Mobile Safe Apps | | [Ticket to Ride® Companion](https://marlvel.ai/intel-report/board/ticket-to-ride-companion-1) | 2.9/5 | Frustrated | Marmalade Game Studio | | [Battle Grid Companion](https://marlvel.ai/intel-report/tools/battle-grid-companion-1) | 1.9/5 | Upset | Marmalade Game Studio | | [Lucky Rollers](https://marlvel.ai/intel-report/games/lucky-rollers) | 3.7/5 | Frustrated | FunCraft, Inc | ## Company Profile - **Developer:** Kyeong Cheon Yang - **Website:** [https://detective-note.fresh-air-creativity.com](https://detective-note.fresh-air-creativity.com) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/detective-notes/id6466589007?uo=4) - **Dev Site:** [Official Website](https://detective-note.fresh-air-creativity.com) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*Kingdomino: The Board Game*](https://marlvel.ai/intel-report/games/com-meeplecorp-kingdomino) (Meeple Corp) — 4.9/5 Rating | Positive Sentiment - [*Tombola (Italian Bingo)*](https://marlvel.ai/intel-report/casino/com-mobilesafeapps-tombola) (Mobile Safe Apps) — 4.5/5 Rating | N/A Sentiment - [*Ticket to Ride® Companion*](https://marlvel.ai/intel-report/board/ticket-to-ride-companion-1) (Marmalade Game Studio) — 2.9/5 Rating | Negative Sentiment - [*Battle Grid Companion*](https://marlvel.ai/intel-report/tools/battle-grid-companion-1) (Marmalade Game Studio) — 1.9/5 Rating | Terrible Sentiment - [*Lucky Rollers*](https://marlvel.ai/intel-report/games/lucky-rollers) (FunCraft, Inc) — 3.7/5 Rating | Negative Sentiment - [*Ludo Game : Onilne King Star*](https://marlvel.ai/intel-report/games/ludo-game-onilne-king-star) (sohil kadevar) — 3.8/5 Rating | N/A Sentiment - [*Legends of Splendoria: gems*](https://marlvel.ai/intel-report/games/legends-of-splendoria-gems) (julien DOLAIS) — N/A Rating | N/A Sentiment - [*Gloomhaven Campaign Tracker*](https://marlvel.ai/intel-report/games/gloomhaven-campaign-tracker) (Grzegorz Dziembowski) — 4.8/5 Rating | Positive Sentiment - [*Gloomhaven Scenario Viewer*](https://marlvel.ai/intel-report/games/gloomhaven-scenario-viewer) (Roy Goncalves) — 5.0/5 Rating | Positive Sentiment - [*Board Games Arena - BoardQ*](https://marlvel.ai/intel-report/games/board-games-arena-boardq) (Nikita Bohara) — 5.0/5 Rating | N/A Sentiment ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** — Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** — Identifies the app's core features, monetization model, target audience, and competitive positioning.
