US Market. No publisher influence. > **Key Insight:** Chord Table is a music app by Co-Engineering LLC.. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Music | | **Developer** | Co-Engineering LLC. | | **Pricing** | Free | | **Platforms** | iOS | | **Confidence** | Low (0.05/1.0) | | **Data Age** | 29d | ## Metadata & Market Performance - **Publisher:** Co-Engineering LLC. - **Category:** Music - **Target Audience:** Music students and composers seeking a reference tool for music theory, chord relationships, and modulation. - **Platforms:** iOS - **Version Reviewed:** 1.0.0 - **Report Date:** 2026-09-02 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.05/1.0) - **App Store ID (iOS):** 6476453241 - **Bundle ID:** com.co-engi.chordtable - **Performance Trend:** Declining - **Data Window:** Analysis based on signals collected up to 2026-09-02 ## Executive Snapshot **What it is:** Chord Table is a music theory reference utility for iOS that visualizes diatonic chords and modulation relationships in a grid format. **Why users hire it:** It removes the cognitive friction of manual chord degree calculation for students and composers by providing a color-coded reference table. ## App DNA (Features & Intent) - **[Standard] Chord Table Visualization:** Displays diatonic chords in a grid format for music theory study. - **[Differentiator] Modulation Analysis Tool:** Provides deep analysis of chord modulation intricacies. * *User Intent:* Users seek enhanced value through premium features. - **[Differentiator] Secondary Dominant Highlighting:** Applies distinctive borders to secondary dominants within the chord table. ## Market Position {#market-position} Chord Table occupies a niche position in the Music category as a static reference utility. With zero ratings and no updates since January 2024, the app lacks the momentum of active theory-learning platforms [1, 2]. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all features - **Analysis:** The app is distributed as a free utility with no visible in-app purchases or subscription tiers. ## SWOT Analysis {#swot} **Core Strengths:** - Grid-based diatonic chord visualization - Modulation analysis tool for complex theory - Color-coded secondary dominant guides **Growth Levers:** - Interactive playback for chord visualization - Mobile-first theory exercises for students ## Recent Changes (v2 → v3) {#recent-changes} The app's competitive outlook shifted from mixed to declining as the lack of development activity now poses a direct risk of store removal. No functional changes occurred, but the analytical framework now explicitly identifies the absence of interactive features as a primary weakness. **Overall trend**: Declining **Compared at**: 2026-09-02 ### Medium-impact changes - **[Added] Expanded SWOT analysis** (swot) - **[Shifted] Outlook trend downgrade** (positioning) ## App Momentum (Zombie) {#momentum} - No updates for 31 months. - Zero store ratings recorded. > **Cadence:** 1 total versions · 1 majors in last 6 months · 953 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Chord Table is a music app that is completely free. > **Bottom Line:** Chord Table serves as a static reference for music theory, but the lack of updates since early 2024 leaves it vulnerable to more interactive competitors, suggesting a need for a maintenance release to ensure continued store presence. **Best for:** Music students and composers seeking a reference tool for music theory, chord relationships, and modulation. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit the current codebase to determine if a maintenance release is viable because the app has been silent for 31 months → restore store visibility ### Outlook: Declining The music theory utility market is shifting toward interactive, gamified learning experiences that integrate ear training with reference tools. Chord Table remains a static grid, which will likely lead to further obscurity as users prioritize tools that offer active engagement over passive reference. - 🔴 The lack of updates since January 2024 indicates the app is in maintenance mode, which prevents it from competing with modern, interactive theory tools. - 🔴 Zero store ratings suggest the app has failed to gain traction or visibility, limiting its potential for organic growth in the Music category. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Chord Table** (this app) | N/A/5 | N/A | Co-Engineering LLC. | | [SyncTimer - Ensemble Stopwatch](https://marlvel.ai/apps/synctimer-ensemble-stopwatch) | 5.0/5 | Thrilled | Sebastian Suarez-Solis | | [BandLab – Music Maker & Beats](https://marlvel.ai/apps/bandlab-music-maker-beats) | 4.8/5 | n/a | BandLab Singapore Pte Ltd | | [Suno - AI Songs, Music, Lyrics](https://marlvel.ai/apps/suno-ai-songs-music) | 4.0/5 | Mixed | Suno, Inc. | | [ヨルシカ](https://marlvel.ai/apps/com-yorushika-sp) | 4.8/5 | N/A | Fanplus, Inc. | | [あいみょん](https://marlvel.ai/apps/net-aimyong-sp) | 4.5/5 | N/A | Fanplus, Inc. | ## Company Profile - **Developer:** Co-Engineering LLC. ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/chord-table/id6476453241?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*SyncTimer - Ensemble Stopwatch*](https://marlvel.ai/apps/synctimer-ensemble-stopwatch) (Sebastian Suarez-Solis) · 5.0/5 Rating | Excellent Sentiment - [*BandLab – Music Maker & Beats*](https://marlvel.ai/apps/bandlab-music-maker-beats) (BandLab Singapore Pte Ltd) · 4.8/5 Rating - [*Suno - AI Songs, Music, Lyrics*](https://marlvel.ai/apps/suno-ai-songs-music) (Suno, Inc.) · 4.0/5 Rating - [*ヨルシカ*](https://marlvel.ai/apps/com-yorushika-sp) (Fanplus, Inc.) · 4.8/5 Rating - [*あいみょん*](https://marlvel.ai/apps/net-aimyong-sp) (Fanplus, Inc.) · 4.5/5 Rating - [*イントリズム*](https://marlvel.ai/apps/jp-rc-into-rhythm) (RedinC) · 3.5/5 Rating - [*クリープハイプ*](https://marlvel.ai/apps/creephyp-sp-browsingapp) (Fanplus, Inc.) · N/A Rating - [*マカロニえんぴつ*](https://marlvel.ai/apps/com-macaroniempitsu-fc) (Fanplus, Inc.) · 3.1/5 Rating - [*100.1 Jack FM*](https://marlvel.ai/apps/100-1-jack-fm) (NRG Media) · 1.0/5 Rating - [*100.1 WJRZ*](https://marlvel.ai/apps/100-1-wjrz) (Beasley Broadcast Group) · 4.8/5 Rating | Excellent Sentiment ## Frequently Asked Questions {#faq} ### Is Chord Table suitable for beginners learning music theory? Chord Table is designed as a reference tool for diatonic chords and modulation. While it provides clear visualization, it lacks interactive exercises or tutorials, making it better suited for students who already have a basic understanding of theory. ### How does Chord Table compare to other music theory apps? Unlike many theory apps that focus on instrument-specific fingerings or gamified ear training, Chord Table functions as a static reference grid for analyzing chord relationships and modulation. ### Does Chord Table require an internet connection? Chord Table is a reference utility. While the app does not explicitly state offline requirements, its nature as a static tool suggests it functions without a constant connection, though progress sync or updates would require one. ## 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.
