Its lack of updates since 2023 contrasts with the high-precision requirements of the industry, signaling a potential gap in reliability for professional users. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is currently offered as a free utility with no visible in-app purchases or subscription tiers. ## SWOT Analysis {#swot} **Core Strengths:** - Adherence to SS 600 and ASTM standards establishes technical authority **Growth Levers:** - Integration of historical fuel price tracking could provide a recurring retention loop ## Recent Changes (v2 → v3) {#recent-changes} The app's competitive outlook has shifted from a neutral observation of dormancy to an active recommendation for sunsetting, driven by the persistent 35-month development freeze and the resulting risk of regulatory non-compliance. **Overall trend**: Declining **Compared at**: 2026-08-05 ### High-impact changes - **[Shifted] Strategic Recommendation Pivot** (positioning) ### Medium-impact changes - **[Removed] SWOT Item Consolidation** (swot) - **[Shifted] Outlook Narrative Tone** (positioning) ## App Momentum (Zombie) {#momentum} - Dormant for 35 months. - No updates since September 2023. > **Cadence:** 1 total versions · 1 majors in last 6 months · 1064 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} MMS - Bunker Fuel Calculator is an utilities app that is completely free. It holds a 5/5 rating from 2 reviews. > **Bottom Line:** Bunker Fuel Calculator provides a necessary, compliant utility for maritime professionals, but the 35-month development freeze risks the tool's long-term viability. If the calculation logic remains current, the tool serves its purpose; if standards have evolved, the app is a liability for its users. **Best for:** Vessel representatives, chief engineers, and fuel buyers requiring precise bunker fuel calculations. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit calculation logic against the latest SS 600 and ASTM revisions because the app has been dormant for 35 months → ensure continued regulatory compliance ### Outlook: Declining The maritime utility market requires high-precision, up-to-date tools that reflect current regulatory standards. Bunker Fuel Calculator's prolonged inactivity suggests it is no longer a viable long-term solution for professional vessel representatives who need reliable, current data. - 🔴 The 35-month development gap indicates the app is in maintenance-only mode, which risks obsolescence as maritime industry standards evolve. - ⚪ The lack of recent updates means the app may fail to support newer iOS versions, eventually eroding its utility for professional users. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 5/5 | | Total Reviews | 2 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **MMS - Bunker Fuel Calculator** (this app) | 5/5 | N/A | Norvin Teo | | [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) | 4.4/5 | Mixed | Fuxin Technology | | [Potatso](https://marlvel.ai/apps/potatso) | 4.4/5 | n/a | Potatso Lab LTD | | [Quantumult X](https://marlvel.ai/apps/quantumult-x) | 3.8/5 | N/A | Cross Utility Ltd | ## Company Profile - **Developer:** Norvin Teo ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/mms-bunker-fuel-calculator/id6456887650?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*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) · 4.6/5 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 - [*근로자 공수달력*](https://marlvel.ai/apps/jaehwan-worktracer) (jaehwan lee) · N/A Rating ## Frequently Asked Questions {#faq} ### Is Bunker Fuel Calculator accurate for professional use? Bunker Fuel Calculator adheres to SS 600 and ASTM standards, which are industry benchmarks for bunker fuel calculations. However, the app has not been updated since September 2023, so users should verify if these standards have changed since that time. ### Does Bunker Fuel Calculator require a subscription? No, Bunker Fuel Calculator is currently offered as a free utility with no in-app purchases or subscription tiers. ### What are the limitations of Bunker Fuel Calculator? The primary limitation is the lack of development updates since 2023.
