The primary shift is a more focused articulation of competitive threats and opportunities within the SWOT analysis. **Overall trend**: Stable **Compared at**: 2026-08-30 ### Medium-impact changes - **[Shifted] SWOT Analysis Consolidation** (swot) ### Low-impact changes - **[Shifted] Outlook Trend Adjustment** (positioning) ## App Momentum (Maintenance) {#momentum} - Quiet 4 months, bug fixes only. - Last major release April 2026. > **Cadence:** 1 total versions · 0 majors in last 6 months · 125 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Refrigerant Charge Calculator is an utilities app that is completely free. It holds a 4.6/5 rating from 15 reviews. > **Bottom Line:** Maintaining the current offline-first utility is essential for field retention, but the lack of recent updates risks obsolescence as A2L refrigerant adoption accelerates. **Best for:** Residential and light-commercial HVAC service technicians, refrigeration techs, and apprentices. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit A2L refrigerant support because the current list lacks recent updates → maintain competitive relevance ### Outlook: Stable The HVAC utility market is shifting toward integrated compliance and diagnostic suites, putting pressure on standalone calculators. Refrigerant Charge Calculator remains advantaged by its offline-first design, but the lack of recent updates suggests it may struggle to keep pace with industry-wide transitions to low-GWP refrigerants. - 🔴 The 125-day update gap indicates a maintenance-only posture, which limits the ability to respond to emerging A2L refrigerant standards. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.6/5 | | Total Reviews | 15 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Refrigerant Charge Calculator** (this app) | 4.6/5 | N/A | Mikhail Nikitin | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [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 | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.5/5 | Mixed | Fuxin Technology | ## Company Profile - **Developer:** Mikhail Nikitin ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/refrigerant-charge-calculator/id6762469018?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.9/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*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) · 4.5/5 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 - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating - [*로또 황금번호 생성기*](https://marlvel.ai/apps/lotto-lottogold) (jaehwan lee) · N/A Rating - [*도사폰 (만세력 역학도구)*](https://marlvel.ai/apps/app--656) (Softchaser Company Limited) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Refrigerant Charge Calculator free to use?
