With only one store rating, the app lacks the visibility and social proof required to compete with broader engineering toolsets. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is offered as a free utility with no visible in-app purchases or subscription tiers. ## SWOT Analysis {#swot} **Core Strengths:** - Real-time preview mechanism verifies design feasibility instantly. - Specialized support for multiple gear types provides technical depth. **Growth Levers:** - Export functionality for CAD software would increase professional utility. - Expansion into material property tables could broaden the user base. ## Recent Changes (v2 → v3) {#recent-changes} Development remains dormant with no feature or pricing changes; the only shifts are in the analytical framework regarding competitive threats and market visibility. **Overall trend**: Stable **Compared at**: 2026-08-18 ### High-impact changes - **[Added] Expanded SWOT Analysis** (swot) ### Medium-impact changes - **[Shifted] Market Visibility Narrative** (positioning) ## What's New - **Latest (v1.0.2, 1 years ago):** General bug fixes and stability improvements. ## App Momentum (Zombie) {#momentum} - No updates in over 700 days. - Development velocity remains dormant. > **Cadence:** 1 total versions · 0 majors in last 6 months · 712 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Gear Calculator Pro is an utilities app that is completely free. It holds a 5/5 rating from 1 review. > **Bottom Line:** Gear Calculator Pro provides a functional, specialized toolset for gear design, but the lack of development velocity suggests it is a legacy project. Maintaining basic OS compatibility is the only move that prevents the tool from becoming obsolete. **Best for:** Mechanical engineers and students requiring quick reference tools for gear design parameters. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit compatibility for the latest iOS version because the app has been dormant for 713 days → ensure basic utility remains functional ### Outlook: Declining The mechanical design utility market is consolidating around tools that offer cloud-sync and CAD integration. Gear Calculator Pro's stagnant development cadence leaves it exposed to platform-level deprecation, which will likely erode its utility for professional users within the next two quarters. - 🔴 The 713-day update gap indicates the app is in maintenance mode, which risks total obsolescence as iOS system requirements evolve. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 5/5 | | Total Reviews | 1 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Gear Calculator Pro** (this app) | 5/5 | N/A | 志桂 李 | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | N/A | Cat Connect | | [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 | ## Company Profile - **Developer:** 志桂 李 ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/gear-calculator-pro/id6463792360?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 - [*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 ## Frequently Asked Questions {#faq} ### Is Gear Calculator Pro suitable for professional engineering work?
