(Strategic Takeaway) {#so-what} RC Speed Calculator Pro is a market-leading utilities app that is completely free. With a 4.9/5 rating from 87 reviews, it delivers strong user satisfaction. > **Bottom Line:** RC Speed Calculator Pro provides a functional, high-rated utility for hobbyists, but the developer's shift to the newer Pit Calc Pro suite makes further investment in this app redundant, so the PM should focus on migrating the existing user base to the new platform. **Best for:** RC car hobbyists and competitive racers requiring precise technical adjustments. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset this app because the latest release redirects users to the newer Pit Calc Pro suite → minimize support overhead. ### Outlook: Stable The app is effectively in maintenance mode as the developer consolidates users into the newer Pit Calc Pro suite. Continued reliance on this legacy tool will likely result in user churn as the newer suite receives active feature development. - ⚪ The app has been silent for over 17 months, with the latest release directing users to a different product. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.9/5 | | Total Reviews | 87 | | Sentiment | Thrilled (92/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **RC Speed Calculator Pro** (this app) | 4.9/5 | Thrilled | Degree3, Inc. | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.5/5 | Mixed | Free VPN LLC | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.4/5 | Mixed | Fuxin Technology | | [Potatso](https://marlvel.ai/apps/potatso) | 4.4/5 | n/a | Potatso Lab LTD | | [Quantumult X](https://marlvel.ai/apps/quantumult-x) | 3.8/5 | N/A | Cross Utility Ltd | ## Company Profile - **Developer:** Degree3, Inc. - **Website:** [https://www.sodialed.com/apps/rc-speed-calculator-pro-app](https://www.sodialed.com/apps/rc-speed-calculator-pro-app) - **Social:** [Facebook](https://www.facebook.com/sodialed) · [YouTube](https://www.youtube.com/channel/UCzcRcALRZDIf2zQTHhznMxQ) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/rc-speed-calculator-pro/id6445860835?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.sodialed.speedcalculator&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.sodialed.com/apps/rc-speed-calculator-pro-app) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.5/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.4/5 Rating - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 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 ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
