US Market. No publisher influence. > **Key Insight:** Sprocket: Bike Gear Calculator is a sports app by Linh Phan Nhat Khanh. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Sports | | **Developer** | Linh Phan Nhat Khanh | | **Pricing** | Subscription | | **Platforms** | iOS | | **Confidence** | Low (0.3/1.0) | | **Data Age** | 13d | ## Metadata & Market Performance - **Publisher:** Linh Phan Nhat Khanh - **Category:** Sports - **Target Audience:** Road, gravel, MTB, and touring cyclists who perform their own drivetrain maintenance or build custom bike configurations. - **Platforms:** iOS - **Version Reviewed:** 1.1.0 - **Report Date:** 2026-09-18 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.3/1.0) - **App Store ID (iOS):** 6771944630 - **Bundle ID:** com.sprocket.bikegear - **Data Window:** Analysis based on signals collected up to 2026-09-18 ## Executive Snapshot **What it is:** Sprocket is a bike gear calculator for road, gravel, and MTB cyclists, offering live drivetrain metrics and setup management on iOS. **Why users hire it:** Cyclists need precise gear-ratio data to plan drivetrain swaps and build custom configurations without relying on trial-and-error part changes. ## App DNA (Features & Intent) - **[Standard] Live Drivetrain Calculations:** Calculates gear ratio, gain ratio, gear inches, and speed based on user-input chainring, cog, cadence, and wheel size. * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior. - **[Differentiator] Custom Cassette Entry:** Allows users to define specific cog sequences for non-standard drivetrain builds. * *User Intent:* Users value self-expression and personalized experiences. - **[Standard] Saved Bike Setups:** Stores named configurations of chainring, cassette, and wheel size for quick comparison. * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior. - **[Differentiator] Offline-First Architecture:** Operates entirely without network connection, storing all data locally on the device. * *User Intent:* Users want uninterrupted access without internet dependency. ## Market Position {#market-position} Sprocket occupies a niche utility space within the Sports category, relying on a subscription model to monetize drivetrain math. The lack of updates for over 90 days suggests a maintenance-mode posture that limits its ability to compete with more active tools. ## Monetization Strategy - **Model:** Subscription - **Tiers:** Free tier with limited access, Premium tier at $9.99/week or $49.99/year - **Analysis:** Subscription model anchored at $49.99/year, gating advanced customization and unlimited storage behind a premium paywall. ## SWOT Analysis {#swot} **Core Strengths:** - Offline-first architecture removes connectivity dependency **Growth Levers:** - Localized cassette presets for regional racing standards ## What's New - **Latest (v1.1.0, 3 months ago):** Launched a comprehensive drivetrain calculator featuring live gear ratio metrics, customizable cassette presets, and saved bike setup management. ## App Momentum (Maintenance) {#momentum} - Ships no updates since June 2026. - Maintains maintenance-mode release cadence. > **Cadence:** 1 total versions · 1 majors in last 6 months · 93 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Sprocket: Bike Gear Calculator is a sports app. > **Bottom Line:** Sprocket's offline-first utility provides a strong foundation, but the current maintenance-mode cadence leaves the product vulnerable to more active competitors. Pivoting to a more accessible pricing structure would unlock the user funnel and better align with the tool's specialized utility. **Best for:** Road, gravel, MTB, and touring cyclists who perform their own drivetrain maintenance or build custom bike configurations. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Audit premium paywall conversion because the $49.99/year price point is high for a single-utility tool → increase conversion velocity ### Outlook: Mixed The cycling utility market is consolidating around tools that offer frequent drivetrain updates and community-driven setup sharing. Sprocket's current maintenance-mode posture leaves it exposed to rivals that can iterate on new drivetrain standards faster, which will likely compress its market share over the next two quarters. - 🔴 The three-month development silence suggests a lack of active feature investment, which erodes the competitive edge against more frequently updated cycling tools. - ⚪ The offline-first architecture remains a stable differentiator that protects the core user base from connectivity-related churn in remote riding environments. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Subscription | | Platforms | iOS | | Key Features | 4 analyzed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Sprocket: Bike Gear Calculator** (this app) | N/A/5 | N/A | Linh Phan Nhat Khanh | | [플레이공](https://marlvel.ai/apps/com-tychesoft-playball) | N/A/5 | N/A | Tychesoft | | [더블이글 - 요즘 골프예약](https://marlvel.ai/apps/com-albatrss-de) | 4.0/5 | N/A | Double Eagle Inc. | | [테니스타운](https://marlvel.ai/apps/com-momzit-tennistown) | 3.5/5 | N/A | link.tennistown | | [イッツゴーン！ボイス](https://marlvel.ai/apps/jp-co-gaora-itsgone) | N/A/5 | N/A | GAORA Inc. | | [トニーくんのビッグバンサーブ](https://marlvel.ai/apps/jp-hase-volley4) | 4.0/5 | N/A | hasegawa takuji | ## Company Profile - **Developer:** Linh Phan Nhat Khanh - **Website:** [https://pnkl26.web.app](https://pnkl26.web.app) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/sprocket-bike-gear-calculator/id6771944630?uo=4) - **Dev Site:** [Official Website](https://pnkl26.web.app) - **Sources:** Developer website content, About us / company information, App store metadata. ## Related Intel Reports - [*플레이공*](https://marlvel.ai/apps/com-tychesoft-playball) (Tychesoft) · N/A Rating - [*더블이글 - 요즘 골프예약*](https://marlvel.ai/apps/com-albatrss-de) (Double Eagle Inc.) · 4.0/5 Rating - [*테니스타운*](https://marlvel.ai/apps/com-momzit-tennistown) (link.tennistown) · 3.5/5 Rating - [*イッツゴーン！ボイス*](https://marlvel.ai/apps/jp-co-gaora-itsgone) (GAORA Inc.) · N/A Rating - [*トニーくんのビッグバンサーブ*](https://marlvel.ai/apps/jp-hase-volley4) (hasegawa takuji) · 4.0/5 Rating - [*00:36*](https://marlvel.ai/apps/00-36) (Adriaan de Jongh) · N/A Rating - [*하루 1루*](https://marlvel.ai/apps/randori-onebaseaday) (hyunseo kim) · 5.0/5 Rating - [*10,000 Shots*](https://marlvel.ai/apps/10-000-shots) (Jeremy Rupke) · 4.8/5 Rating - [*100 Climbs of Italy*](https://marlvel.ai/apps/100-climbs-of-italy) (100 Climbs limited) · N/A Rating - [*100 Climbs of Spain*](https://marlvel.ai/apps/100-climbs-of-spain) (100 Climbs limited) · N/A Rating ## Frequently Asked Questions {#faq} ### Is Sprocket worth paying for if I only need occasional gear math? Sprocket offers a free tier for basic calculations, but the premium subscription is required for unlimited bike setups and custom cassette entry.
