It holds a 2.33/5 rating from 3 reviews. > **Bottom Line:** Dilution Calculator serves as a static utility that has been surpassed by modern, integrated agricultural management platforms. The lack of development for over a decade confirms that the app is in sunset status, and users should be directed to more current, cloud-enabled alternatives. **Best for:** Farmers, gardeners, and agricultural professionals requiring precise chemical dilution ratios. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the app because the 10-year development gap makes feature parity impossible → stop resource drain on a non-viable product ### Outlook: Declining The agricultural utility market is consolidating around platforms that offer integrated inventory and compliance logging. Dilution Calculator remains a static, legacy tool that fails to provide the data-sync or regulatory features required by modern professionals, signaling a total loss of competitive relevance. - 🔴 The 10-year development gap confirms a maintenance-only cadence, which prevents the app from addressing modern agricultural compliance needs. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2.33/5 | | Total Reviews | 3 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Dilution Calculator** (this app) | 2.33/5 | N/A | Koji Iida | | [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 | | [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) | 4.5/5 | Mixed | Fuxin Technology | ## Company Profile - **Developer:** Koji Iida ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/dilution-calculator/id955305524?uo=4) - **Sources:** 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 - [*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) · 4.5/5 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 - [*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 ## Frequently Asked Questions {#faq} ### Is Dilution Calculator still being updated?
