(Strategic Takeaway) {#so-what} Ratio Calculator Tool is an utilities app that is completely free. It holds a 3.15/5 rating from 13 reviews. > **Bottom Line:** The lack of updates since 2021 signals that Ratio Calculator Tool is in maintenance mode, leaving the app vulnerable to displacement by modern, ad-free alternatives. Addressing the clipboard automation would improve retention, but the current stagnant development cadence limits the app's ability to compete. **Best for:** Users requiring quick, specific calculations for direct and inverse proportions in daily tasks. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship a toggle for clipboard automation because it is the top-requested fix → reduce user frustration ### Outlook: Stable The utilities market is consolidating around tools that offer ad-free experiences and flexible input methods, leaving Ratio Calculator Tool exposed. Without a shift in development cadence, the app will likely continue to lose ground to more responsive, modern competitors. - 🔴 The five-year development silence indicates the app is in maintenance mode, which increases the risk of OS-level incompatibility and user churn. - 🔴 Aggressive clipboard automation without user consent drives negative sentiment, which compounds the rating drag already visible in the store data. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.15/5 | | Total Reviews | 13 | | Sentiment | Mixed (45/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Ratio Calculator Tool** (this app) | 3.15/5 | Mixed | Kubilay Erdogan | | [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:** Kubilay Erdogan - **Website:** [https://kubilayerdogan.net/](https://kubilayerdogan.net/) - **Social:** [X/Twitter](https://twitter.com/kublaios) ## Data Sources & Links - **App Store ID:** 879213465 - **Dev Site:** [Official Website](https://kubilayerdogan.net/) - **Sources:** Developer website content, App store metadata, User reviews. ## 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 Ratio Calculator Tool suitable for professional use?
