(Strategic Takeaway) {#so-what} Amperes 4- battery charge info is an utilities app that is free with in-app purchases. With a 4.5/5 rating from 327.4K reviews, it shows mixed user reception. > **Bottom Line:** Amperes 4- provides a reliable diagnostic mechanism for hardware enthusiasts, but the latest update's performance regressions and lack of hardware-compatibility transparency threaten its reputation, so the team must prioritize stability fixes to prevent further churn. **Best for:** Tech-savvy users and hardware enthusiasts looking to diagnose charging performance of cables, chargers, and battery health. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Fix testing-hang regressions in the next release because they are the #1 churn driver → stabilize the rating baseline ### Feature Gaps vs Competitors - Real-time monitoring dashboard (available in generalized battery monitors but missing here) ### Outlook: Declining The utility market is consolidating around high-frequency, stable tools, leaving Amperes 4- exposed due to its slow, unreliable testing mechanism on modern operating systems. Unless the team addresses the testing hangs and improves disclosure, the app will continue to bleed users to more stable, generalized alternatives. - 🔴 Post-update performance regressions cause the app to hang indefinitely, which compounds the rating drag already visible on Android. - 🔴 User accusations of deceptive marketing regarding hardware compatibility erode trust, likely leading to increased refund requests in the coming quarter. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.5/5 | | Total Reviews | 327.4K | | Sentiment | Mixed (45/100) | | Confidence | High | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Amperes 4- battery charge info** (this app) | 4.5/5 | Mixed | CrioSoft LLC | | [Cleaner Kit - Clean Up Storage](https://marlvel.ai/apps/bp-rmaster-free) | 4.4/5 | Mixed | BPMobile | | [1.1.1.1: Faster Internet](https://marlvel.ai/apps/com-cloudflare-1dot1dot1dot1) | 4.5/5 | Mixed | Cloudflare | | [Battery HD+](https://marlvel.ai/apps/battery-hd) | 4.6/5 | Excited | smalltech sarl | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.5/5 | Mixed | Free VPN LLC | ## Company Profile - **Developer:** CrioSoft LLC - **Website:** [https://www.criosoft.com/amperes](https://www.criosoft.com/amperes) - **Social:** [Facebook](https://www.facebook.com/pages/category/Software-Company/CrioSoft-279931649214589) · [LinkedIn](https://www.linkedin.com/company/criosoft) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/amperes-4-battery-charge-info/id1245475416?uo=2) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.gombosdev.ampere&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.criosoft.com/amperes) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*Cleaner Kit - Clean Up Storage*](https://marlvel.ai/apps/bp-rmaster-free) (BPMobile) · 4.4/5 Rating - [*1.1.1.1: Faster Internet*](https://marlvel.ai/apps/com-cloudflare-1dot1dot1dot1) (Cloudflare) · 4.5/5 Rating - [*Battery HD+*](https://marlvel.ai/apps/battery-hd) (smalltech sarl) · 4.6/5 Rating | Positive Sentiment - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.5/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.4/5 Rating - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.5/5 Rating - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating ## Frequently Asked Questions {#faq} ### Is Amperes 4- accurate for measuring battery health? The app is not meant to be mA accurate. It is designed to relatively measure how various chargers and USB cables perform on the same device. ### Why does the app show 0mA during testing? Some devices lack an appropriate measurement chip. If the app shows 0mA, you can try the 'Old measurement method' in settings if your device supports it. ### Is Amperes 4- compatible with all Android phones? No, not every device is supported. Some phones lack the necessary measurement interface, and the app description lists several incompatible models. ### What is the difference between the free and paid versions? The Android version is free and ad-supported, while the iOS version is a one-time paid purchase. Premium features include widgets, notifications, and alerts. ## 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.
