US Market. No publisher influence. > **Key Insight:** Pulley Calculator Easy is a utilities app by YAVUZ BULAMADIK. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Utilities | | **Developer** | YAVUZ BULAMADIK | | **Pricing** | Free | | **Platforms** | iOS | | **Confidence** | Low (0.05/1.0) | | **Data Age** | 42d | ## Metadata & Market Performance - **Publisher:** YAVUZ BULAMADIK - **Category:** Utilities - **Target Audience:** Mechanical engineers, technicians, machinists, and DIY enthusiasts requiring on-site belt drive system calculations. - **Platforms:** iOS - **Version Reviewed:** 1.0 - **Report Date:** 2026-09-18 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.05/1.0) - **App Store ID (iOS):** 6777316736 - **Bundle ID:** com.yavuzbulamadik.Rpm - **Data Window:** Analysis based on signals collected up to 2026-09-18 ## Executive Snapshot **What it is:** Pulley Calculator Easy is a mechanical engineering utility for belt drive system calculations, available as a free tool on iOS. **Why users hire it:** The app removes the cognitive friction of manual formula lookups for on-site technicians and machinists. ## App DNA (Features & Intent) - **[Standard] Belt Speed Calculator:** Computes linear belt speed in multiple units based on pulley diameter and RPM inputs. - **[Standard] Belt Length Calculator:** Calculates required belt length using pulley diameters and center distance. - **[Standard] Pulley Ratio Calculator:** Determines mechanical drive ratio to optimize torque and RPM output. - **[Basic] Unit Converter:** Converts speed and power units within the calculation interface. ## Market Position {#market-position} Pulley Calculator Easy occupies a niche utility space with zero updates since its June 2026 release. The lack of a monetization model or premium tier suggests a developer focus on utility rather than commercial growth. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is distributed as a free utility with no in-app purchases or subscription tiers, limiting long-term revenue potential. ## SWOT Analysis {#swot} **Core Strengths:** - Interface design eliminates nested menus for rapid on-site calculation **Growth Levers:** - Integrating industrial belt databases creates a defensible utility barrier ## App Momentum (Maintenance) {#momentum} - No updates since June 2026 launch. - Maintenance-mode development cycle. > **Cadence:** 1 total versions · 0 majors in last 6 months · 100 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Pulley Calculator Easy is an utilities app that is completely free. > **Bottom Line:** The lack of development cadence since the June 2026 launch invalidates the current passive strategy, and a pivot to a freemium model would unlock the resources needed to build a defensible industrial database. **Best for:** Mechanical engineers, technicians, machinists, and DIY enthusiasts requiring on-site belt drive system calculations. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Audit user retention because the app has been in maintenance mode since launch → determine if a pivot to a freemium model is viable ### Outlook: Declining The engineering utility market is shifting toward tools that provide integrated material databases, rendering simple formula calculators less competitive. Pulley Calculator Easy remains exposed due to its static feature set, and without a shift to a sustainable monetization model, it will likely lose visibility to more actively maintained alternatives. - 🔴 Zero updates since the June 2026 launch indicate a dormant product lifecycle, which erodes user trust in the tool's long-term utility. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 4 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Pulley Calculator Easy** (this app) | N/A/5 | N/A | YAVUZ BULAMADIK | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.8/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.5/5 | Mixed | Fuxin Technology | | [VPN 365-Master WIFI Security](https://marlvel.ai/apps/vpn-365-master-wifi-security) | 4.6/5 | n/a | vpn fast | ## Company Profile - **Developer:** YAVUZ BULAMADIK ## Data Sources & Links - **App Store ID:** 6777316736 - **Sources:** App store metadata. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*VPN 365-Master WIFI Security*](https://marlvel.ai/apps/vpn-365-master-wifi-security) (vpn fast) · 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 - [*근로자 공수달력*](https://marlvel.ai/apps/jaehwan-worktracer) (jaehwan lee) · N/A Rating - [*レジュメ*](https://marlvel.ai/apps/app--54) (Indeed Inc.) · 2.2/5 Rating ## Frequently Asked Questions {#faq} ### Is Pulley Calculator Easy suitable for professional engineering use?
