No major releases in 5 years. - Maintenance-mode status since October 2020. > **Cadence:** 1 total versions · 0 majors in last 6 months · 2106 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} PowerMon is a market-leading utilities app that is completely free. With a 4.5/5 rating from 32 reviews, it delivers strong user satisfaction. > **Bottom Line:** PowerMon's reliance on legacy hardware integration without cloud-sync support limits its long-term viability against modern rivals. Addressing the data-logging regressions is the only way to retain the professional user base that currently relies on the tool for system maintenance. **Best for:** Owners of RVs, boats, and solar systems who require precise energy storage and battery monitoring. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit data-sync logic because it is the top-reported complaint → reduce churn ### Feature Gaps vs Competitors - Cloud-based history logging (available in BatteryShare but missing here) ### Outlook: Declining The utility market is consolidating around cloud-enabled monitoring, leaving PowerMon's local-only architecture increasingly isolated. Without a return to active development, the app will continue to lose its professional user base to competitors that offer modern synchronization and automation features. - 🔴 Persistent data synchronization failures in the latest version erode the daily active habit, which compounds the rating drag already visible on Android. - 🔴 The five-year update gap signals a maintenance-mode posture, leaving the app vulnerable to rivals with active two-week release cadences. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.5/5 | | Total Reviews | 32 | | Sentiment | Thrilled (85/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **PowerMon** (this app) | 4.5/5 | Thrilled | Thornwave Labs Inc | | [Amperes 4- battery charge info](https://marlvel.ai/apps/com-criosoft-amperes1) | 4.5/5 | Excited | CrioSoft LLC | | [CueTrack](https://marlvel.ai/apps/cuetrack) | 5.0/5 | N/A | Daniel Murfin | | [NetForge: Engineer's Toolkit](https://marlvel.ai/apps/netforge-engineer-s-toolkit) | N/A/5 | N/A | Andy Arevalo | | [Allegion ENGAGE](https://marlvel.ai/apps/allegion-engage) | 2.2/5 | N/A | Schlage Lock Company | | [CowManager App](https://marlvel.ai/apps/cowmanager-app) | 3.0/5 | N/A | CowManager B.V. | ## Company Profile - **Developer:** Thornwave Labs Inc - **Website:** [https://www.thornwave.com/products-btdcpm](https://www.thornwave.com/products-btdcpm) - **Social:** [Instagram](https://www.instagram.com/thornwavelabs) · [Facebook](https://www.facebook.com/thornwave) · [YouTube](https://www.youtube.com/channel/UCBe4iTXcstumGGGvIixCdyg) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/powermon/id1289006249?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.thornwave.powermon&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.thornwave.com/products-btdcpm) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*Amperes 4- battery charge info*](https://marlvel.ai/apps/com-criosoft-amperes1) (CrioSoft LLC) · 4.5/5 Rating | Positive Sentiment - [*CueTrack*](https://marlvel.ai/apps/cuetrack) (Daniel Murfin) · 5.0/5 Rating - [*NetForge: Engineer's Toolkit*](https://marlvel.ai/apps/netforge-engineer-s-toolkit) (Andy Arevalo) · N/A Rating - [*Allegion ENGAGE*](https://marlvel.ai/apps/allegion-engage) (Schlage Lock Company) · 2.2/5 Rating - [*CowManager App*](https://marlvel.ai/apps/cowmanager-app) (CowManager B.V.) · 3.0/5 Rating - [*Cropwise Imagery*](https://marlvel.ai/apps/cropwise-imagery) (Syngenta Digital LTDA) · 5.0/5 Rating | Excellent Sentiment - [*BatteryShare: Remote Sync*](https://marlvel.ai/apps/batteryshare-remote-sync) (Jack Kroll) · N/A Rating - [*Elitech iCold*](https://marlvel.ai/apps/elitech-icold) (Elitech Technology,Inc.) · 3.4/5 Rating - [*Enerdrive ePRO*](https://marlvel.ai/apps/enerdrive-epro) (enerdrive) · N/A Rating - [*BatMon*](https://marlvel.ai/apps/batmon) (Monitor of Things Ltd) · N/A Rating ## Frequently Asked Questions {#faq} ### Is PowerMon compatible with any battery monitor?
