With no public ratings yet, the app currently relies on its unique orientation to differentiate from established scale-reference tools. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free with banner ads - **Analysis:** Ad-supported model using Google AdMob to monetize free access to scale reference tools. ## SWOT Analysis {#swot} **Core Strengths:** - Landscape-first panoramic layout removes vertical scrolling friction **Growth Levers:** - Adding Major and Blues scales would increase retention ## Recent Changes (v2 → v3) {#recent-changes} SHIBAN has refined its competitive narrative, pivoting from a passive maintenance posture to framing its lack of gamification as a deliberate design choice for serious practice. The app continues to operate in a maintenance-only state with no new feature releases. **Overall trend**: Stable **Compared at**: 2026-08-29 ### Medium-impact changes - **[Shifted] Ad-supported model risk** (swot) - **[Shifted] Gamification strategy** (positioning) ### Low-impact changes - **[Added] Blues scale expansion** (swot) ## What's New - **Latest (v1.0.2, 2 months ago):** Applied minor user interface refinements. ## App Momentum (Maintenance) {#momentum} - Ships minor interface refinements only. - Maintains 67-day maintenance-only cadence. > **Cadence:** 1 total versions · 0 majors in last 6 months · 67 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} SHIBAN — Guitar Scales is a music app that is free with in-app purchases. > **Bottom Line:** SHIBAN's landscape-first design addresses a specific ergonomic friction in guitar practice, but the current limited scale library and maintenance-mode cadence cap its retention potential. **Best for:** Guitar learners and musicians seeking a visual reference for scale positions and fretboard navigation. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship Major and Blues scale modules because they are the top-requested roadmap items → increase session frequency ### Outlook: Stable The music education market is shifting toward interactive, gamified platforms, leaving a gap for simple, high-utility reference tools. SHIBAN is well-positioned to serve the practice-stand segment if it expands its scale library to match the breadth of its competitors. - ⚪ The current maintenance-only release cadence indicates a stable, feature-complete utility that is not currently pursuing aggressive growth or expansion. - 🟢 The landscape-first design provides a clear differentiator that serves a specific, underserved segment of guitarists who practice with devices on stands. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **SHIBAN — Guitar Scales** (this app) | N/A/5 | N/A | Yuta Fukutani | | [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. | | [イントリズム](https://marlvel.ai/apps/jp-rc-into-rhythm) | 3.5/5 | N/A | RedinC | ## Company Profile - **Developer:** Yuta Fukutani - **Website:** [https://fuku01.github.io/shiban-support/](https://fuku01.github.io/shiban-support/) ## Data Sources & Links - **App Store ID:** 6778239183 - **Dev Site:** [Official Website](https://fuku01.github.io/shiban-support/) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*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 - [*100.3 The Wolf*](https://marlvel.ai/apps/100-3-the-wolf) (SummitMedia, LLC) · 4.1/5 Rating ## Frequently Asked Questions {#faq} ### Is SHIBAN suitable for beginners?
