The lack of recent feature investment relative to rivals like Z5 signals a loss of competitive relevance. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free version, In-app purchases available - **Analysis:** The app uses a freemium model, though specific premium feature gates are not detailed in the current store presence. ## 🔴 User Sentiment (Low Confidence: 1 of 1 review analyzed) {#user-sentiment} - **Overall Rating:** 1/5 - **Platform Split:** iOS 1.0/5 (1 ratings) - **Overall Sentiment:** Upset ### Top Complaints (Impact Areas) - **The application fails to launch on mobile devices, preventing users from accessing any core functionality** ## SWOT Analysis {#swot} **Core Strengths:** - Specialized speed-cadence graphing establishes category authority **Growth Levers:** - PDF export functionality would address documentation gaps against rivals ## Recent Changes (v3 → v4) {#recent-changes} The product has transitioned from a dormant utility to a non-functional state, with confirmed launch failures rendering the app unusable. This technical collapse has forced a shift in strategic outlook toward sunsetting the current standalone architecture. **Overall trend**: Declining **Compared at**: 2026-10-10 ### High-impact changes - **[Declined] Confirmed Launch Failure** (sentiment) - **[Shifted] Strategic Sunset Recommendation** (positioning) ### Medium-impact changes - **[Added] Critical Technical Weakness** (swot) ## What's New - **Latest (v1.2.54, 8 months ago):** Updated native libraries to support 16KB memory page size for Android 16+ compatibility. ## App Momentum (Zombie) {#momentum} - Dormant for over eight months. - Critical launch failure persists. > **Cadence:** 2 total versions · 0 majors in last 6 months · 251 days since last update · 124 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Gear Ratio Calculator 2 is a sports app that is free with in-app purchases. It holds a 1/5 rating from 1 review. > **Bottom Line:** Gear Ratio Calculator 2 is currently non-functional, and the lack of development investment suggests it cannot compete with modern, data-integrated rivals. Addressing the launch failure is the only path to restoring basic utility for the existing user base. **Best for:** Road bike and mountain bike cyclists looking to analyze and optimize their drivetrain gear ratios. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit launch sequence because users report the app fails to open on mobile devices → restore core utility ### Feature Gaps vs Competitors - Strava integration (available in Z5 but missing here) ### Outlook: Declining The cycling utility market is consolidating around apps that offer automated biomechanical analysis and direct data syncing with platforms like Strava. Gear Ratio Calculator 2 remains isolated as a manual calculator, and its current technical instability suggests it will continue to lose relevance to these integrated alternatives. - 🔴 The eight-month development silence indicates a maintenance-only posture that leaves the app unable to respond to emerging AI-driven competitors. - 🔴 Critical launch failures in the latest release erode user trust, which compounds the existing 1★ rating drag. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 1/5 | | Total Reviews | 1 | | Sentiment | Upset (10/100) | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Gear Ratio Calculator 2** (this app) | 1/5 | Upset | ABT Co., Ltd. | | [SizeMyBike](https://marlvel.ai/apps/com-lapommechezvous-sizemybike) | 2.5/5 | Mixed | La Pomme Chez Vous | | [Z5](https://marlvel.ai/apps/z5-app) | 4.0/5 | N/A | Juan Aristizabal | | [BikeFit AI - Bike Fit Analyzer](https://marlvel.ai/apps/bikefit-ai-bike-fit-analyzer) | N/A/5 | N/A | Jonas Friesslich | | [BMX New Zealand](https://marlvel.ai/apps/bmx-new-zealand) | N/A/5 | N/A | Sportsground | | [SDBR Club](https://marlvel.ai/apps/sdbr-club) | N/A/5 | N/A | Sportsground | ## Company Profile - **Developer:** ABT Co., Ltd. ## Data Sources & Links - **App Store ID:** 6449957065 - **Google Play ID:** jp.abt.gearratio2 - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*SizeMyBike*](https://marlvel.ai/apps/com-lapommechezvous-sizemybike) (La Pomme Chez Vous) · 2.5/5 Rating - [*Z5*](https://marlvel.ai/apps/z5-app) (Juan Aristizabal) · 4.0/5 Rating - [*BikeFit AI - Bike Fit Analyzer*](https://marlvel.ai/apps/bikefit-ai-bike-fit-analyzer) (Jonas Friesslich) · N/A Rating - [*BMX New Zealand*](https://marlvel.ai/apps/bmx-new-zealand) (Sportsground) · N/A Rating - [*SDBR Club*](https://marlvel.ai/apps/sdbr-club) (Sportsground) · N/A Rating - [*BeSoccer: Soccer Live Score*](https://marlvel.ai/apps/besoccer-soccer-live-score-1) (BeSoccer apps) · 4.5/5 Rating | Positive Sentiment - [*BeSoccer: Soccer Live Score*](https://marlvel.ai/apps/besoccer-soccer-live-score) (BESOCCER) · 4.5/5 Rating - [*Football Playbook Animator*](https://marlvel.ai/apps/football-playbook-animator) (BJT Software LLC) · 4.6/5 Rating - [*Football Play Designer*](https://marlvel.ai/apps/football-play-designer) (greg brady) · 4.1/5 Rating - [*QZ Fitness*](https://marlvel.ai/apps/qz-qdomyos-zwift) (Roberto Viola) · 4.8/5 Rating | Excellent Sentiment ## Frequently Asked Questions {#faq} ### Is Gear Ratio Calculator 2 suitable for professional bike fitting? No, the app focuses on mechanical gear ratio and speed-cadence calculations. For professional bike fitting and biomechanical analysis, rivals like SizeMyBike or AI-based analyzers are more appropriate. ### How does Gear Ratio Calculator 2 compare to Z5? Gear Ratio Calculator 2 is a standalone manual calculator, whereas Z5 integrates directly with Strava to sync ride data and provides social-focused features. ### Does Gear Ratio Calculator 2 have any known technical issues? Yes, users report that the application fails to launch on mobile devices, which prevents access to all core functionality. ### What is a free alternative to Gear Ratio Calculator 2?
