The lack of updates since 2017 indicates the developer is not actively competing for market share. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** Gear Ratio Calculator Lite is distributed as a free utility with no in-app purchases or subscription tiers. ## SWOT Analysis {#swot} **Core Strengths:** - Gain Ratio calculation provides a precise metric for drivetrain tuning **Growth Levers:** - Modern mobile-first redesign could capture users relying on spreadsheets ## What's New - **Latest (v3.4.0, 8 years ago):** Stability improvements for iOS 10. ## App Momentum (Zombie) {#momentum} - Dormant for 107 months. - No releases since September 2017. > **Cadence:** 1 total versions · 0 majors in last 6 months · 3258 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Gear Ratio Calculator Lite is an utilities app that is completely free. It holds a 2/5 rating from 6 reviews. > **Bottom Line:** Gear Ratio Calculator Lite provides a functional utility for drivetrain simulation, but the lack of development since 2017 effectively renders it a legacy tool. The PM should sunset the project to focus resources on active product lines. **Best for:** Road bike and mountain bike enthusiasts looking to optimize drivetrain components and gear ratios. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the application because the development cycle has been dormant for over 100 months → eliminate brand drag ### Outlook: Declining The market for cycling utilities is consolidating around apps that offer integrated wearable data and cloud-synced performance tracking. Gear Ratio Calculator Lite remains a static tool, which will likely result in a continued decline in relevance as users migrate to modern, feature-rich alternatives. - 🔴 The 107-month development gap indicates the product is in a permanent maintenance-free state, which will eventually lead to platform incompatibility. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2/5 | | Total Reviews | 6 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Gear Ratio Calculator Lite** (this app) | 2/5 | N/A | ABT Co., Ltd. | | [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:** ABT Co., Ltd. - **Website:** [https://www.abt.jp/](https://www.abt.jp/) - **Social:** [X/Twitter](https://twitter.com/abtjp) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/gear-ratio-calculator-lite/id580455357?uo=4) - **Dev Site:** [Official Website](https://www.abt.jp/) - **Sources:** Developer website content, 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 Ratio Calculator Lite still supported? No, the application has not received a feature update since September 2017, and the developer has not indicated any plans for future development. ### Does Gear Ratio Calculator Lite work offline? Yes, the application functions as a standalone utility and does not require an active internet connection to perform gear ratio or gain ratio calculations. ### What is the difference between Gear Ratio and Gain Ratio? Gear Ratio represents the relationship between the chain wheel and sprocket teeth, while Gain Ratio calculates the actual distance traveled per full crank revolution, providing a more precise measurement for drivetrain tuning. ## 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.
