For Road bike and mountain bike cyclists looking to analyze and optimize their drivetrain gear ratios.
What does it look like?
Key features
Visualizes gear ratios and gain ratios based on specific chainwheel, sprocket, and tire combinations.
Plots speed against cadence for multiple gear positions to identify optimal performance ranges.
How much does it cost?

Velocity
Dormant developmentperformanceplatform expansionShow more...
The development cadence is effectively dormant, with no releases recorded in the last 8 months. The most recent update was a technical maintenance patch for Android 16 compatibility, and there has been no activity on the iOS platform since May 2025. Given the lack of updates for over 240 days, the app is classified as a zombie project.

Key takeaways for Gear Ratio Calculator 2
Where is it heading?
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.
The SWOT
- Specialized speed-cadence graphing establishes category authority
- PDF export functionality would address documentation gaps against rivals

Since the last report: 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.
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.
