Quell Fibromyalgia remains stable but exposed due to its limited feature set and technical performance issues, which will likely lead to increased churn if the development team does not address the core stability complaints. - 🔴 The lack of feature updates over the last six months suggests a shift toward maintenance, which risks losing users to more active health-tracking platforms. - 🔴 Technical complaints regarding battery and thermal management persist, which erodes trust in the app as a reliable daily medical companion. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.27/5 | | Total Reviews | 13 | | Sentiment | Excited (75/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Quell Fibromyalgia** (this app) | 4.27/5 | Excited | NeuroMetrix, Inc. | | [필잇 - 약 알림 및 복용 기록](https://marlvel.ai/apps/app--35) | N/A/5 | N/A | Hansub Yoo | | [레어노트 - 암·희귀질환 정보](https://marlvel.ai/apps/app--629) | 5.0/5 | N/A | LifeX, Inc. | | [창고형약국 약값체크](https://marlvel.ai/apps/com-hiddenwave-yakcheck) | N/A/5 | N/A | Lowkeybase | | [용인세브란스병원](https://marlvel.ai/apps/com-severance-newys) | 1.9/5 | N/A | Yonsei University Health System | | [1001Doktor](https://marlvel.ai/apps/com-binbirdoktor-binbirdoktor) | 4.8/5 | N/A | 1001Doktor Ltd.
