Elegantune Chromatic Tuner Pro remains exposed to churn as modern iOS updates eventually break its legacy audio implementation. - 🔴 The seven-year development gap (last update 2019) suggests the app is in permanent maintenance mode, which increases the risk of sudden session failure. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.79/5 | | Total Reviews | 73 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Elegantune Chromatic Tuner Pro** (this app) | 4.79/5 | N/A | 立毅 成 | | [SyncTimer - Ensemble Stopwatch](https://marlvel.ai/apps/synctimer-ensemble-stopwatch) | 5.0/5 | Thrilled | Sebastian Suarez-Solis | | [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 | | [クリープハイプ](https://marlvel.ai/apps/creephyp-sp-browsingapp) | N/A/5 | N/A | Fanplus, Inc. | ## Company Profile - **Developer:** 立毅 成 ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/elegantune-chromatic-tuner-pro/id690614145?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 - [*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 - [*100.7 KIK-FM*](https://marlvel.ai/apps/100-7-kik-fm) (Hubbard Radio) · 4.3/5 Rating ## Frequently Asked Questions {#faq} ### Is Elegantune Chromatic Tuner Pro still supported?
