Vehicle Setup Simulator:** Side-by-side comparison of current vehicle configurations against potential modifications like tire size, axle ratios, and transmission swaps. * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior. - **[Differentiator] Transmission Presets:** Library of 74 pre-configured transmission gear ratios from major manufacturers like TREMEC, ZF, and Ford. - **[Differentiator] Offline Calculation Engine:** Full functionality for all calculators and simulators without requiring an active internet connection. * *User Intent:* Users want uninterrupted access without internet dependency. ## Market Position {#market-position} Gear Ratio & Speed Calculator occupies a specialized niche in the Utilities category, focusing on technical precision rather than general-purpose automotive content. The absence of public ratings suggests the app is currently in an early adoption phase, requiring a shift toward community-driven growth to establish market presence. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all calculators and simulators - **Analysis:** The app operates on an ad-supported free model with no current IAP or subscription gates. ## SWOT Analysis {#swot} **Core Strengths:** - Offline-first architecture ensures utility in remote garage environments - 74-preset transmission library reduces manual data entry for professional mechanics - What If? simulator provides visual impact analysis for complex drivetrain swaps **Growth Levers:** - Localized pricing or premium ad-free tiers for professional users - Integration of a community-driven database for custom transmission ratios ## What's New - **Latest (v1.1.5, 2 days ago):** Introduced real-time unit persistence for speed and tire formats, alongside refined gear ratio specifications for NV4500 transmissions. ## App Momentum (Active) {#momentum} - Ships two updates every three weeks. - Integrated real-time unit persistence. - Refined NV4500 transmission gear specifications. > **Cadence:** 2 total versions · 1 majors in last 6 months · 2 days since last update · 20 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Gear Ratio & Speed Calculator is an utilities app that is completely free. > **Bottom Line:** Gear Ratio & Speed Calculator provides a high-utility, offline-first simulation engine that serves as a technical planning tool for automotive builders. The current lack of user engagement signals a need to prioritize discoverability and community-driven content to build a user base. **Best for:** Automotive enthusiasts, track racers, off-road builders, and mechanics requiring precise drivetrain and gear ratio calculations. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship social sharing for setup simulations because zero reviews exist → increase organic discovery ### Outlook: Stable Automotive utility tools are increasingly shifting toward community-integrated platforms that allow for custom data sharing. Gear Ratio & Speed Calculator's current focus on offline precision is a strong foundation, but without social-sharing or community-data features, it risks being displaced by web-based tools that offer broader, user-generated datasets. - 🟢 The steady release cadence of two updates in three weeks shows active feature investment rather than maintenance mode. - ⚪ The lack of public user engagement or ratings suggests the app has yet to penetrate the broader automotive enthusiast market. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Gear Ratio & Speed Calculator** (this app) | N/A/5 | N/A | HyeongSeok Oh | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [App For Siri Commands Tips](https://marlvel.ai/apps/app-for-siri-commands-tips) | N/A/5 | N/A | Anh La Phan Son | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Bin Days - Bin Reminder](https://marlvel.ai/apps/bin-days-bin-reminder) | N/A/5 | N/A | Vicki Partridge | ## Company Profile - **Developer:** HyeongSeok Oh - **Website:** [https://domilabs.vercel.app/gear-ratio-calculator](https://domilabs.vercel.app/gear-ratio-calculator) ## Data Sources & Links - **App Store ID:** 6809325091 - **Google Play ID:** com.giftsets.gearratiocalc - **Dev Site:** [Official Website](https://domilabs.vercel.app/gear-ratio-calculator) - **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 - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*App For Siri Commands Tips*](https://marlvel.ai/apps/app-for-siri-commands-tips) (Anh La Phan Son) · N/A Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Bin Days - Bin Reminder*](https://marlvel.ai/apps/bin-days-bin-reminder) (Vicki Partridge) · N/A Rating - [*Controller Tester FGC*](https://marlvel.ai/apps/controller-tester-fgc) (Aaron Lowe) · 5.0/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Gear Ratio Calculator & RPM*](https://marlvel.ai/apps/cog-gear-ratio-calculator) (Linh Phan Nhat Khanh) · N/A Rating - [*MDflow Web Clipper*](https://marlvel.ai/apps/mdflow-web-clipper) (DataOps, s.r.o.) · N/A Rating - [*NordVPN: VPN Fast & Secure*](https://marlvel.ai/apps/com-nordvpn-nordvpn) (Nordvpn S.A.) · 4.7/5 Rating ## Frequently Asked Questions {#faq} ### Is Gear Ratio & Speed Calculator free to use?
