Last major update February 2026. - No notable feature additions recently. > **Cadence:** 2 total versions · 0 majors in last 6 months · 96 days since last update · 202 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Fertilizer Calc App is an established utilities app that is free with in-app purchases. With a 1/5 rating from 1 reviews, it shows polarized user reception. > **Bottom Line:** Fertilizer Calc App provides a specialized elemental calculation tool, but its lack of offline support and high manual-entry friction limits its utility against established rivals, so the PM should prioritize offline functionality to close the competitive gap. **Best for:** Farmers and agricultural professionals needing precise, localized fertilizer application calculations. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [HIGH IMPACT] Ship offline mode because it is the primary utility gap against the nemesis → neutralize the connectivity disadvantage — *Competitor analysis identifies offline sync as a key differentiator for the nemesis, Tank Mix Calculator.* _(trade-off: deprioritize Push the UI redesign sprint to Q4 — offline utility is a higher-impact retention lever.)_ - [ ] [PIVOT] [MEDIUM IMPACT] Build a pre-populated nutrient database because manual entry is the top friction point → increase user retention — *The current manual entry requirement is a barrier to entry compared to established chemical databases.* _(trade-off: deprioritize Pause the custom unit storage expansion — database utility has a higher impact on new-user conversion.)_ - [ ] [MAINTAIN] [HIGH IMPACT] Audit the iOS onboarding flow because the 1-star rating suggests immediate user abandonment → stabilize the rating baseline — *The 1-star rating on iOS indicates a critical failure in the first-time user experience.* _(trade-off: deprioritize Same-quarter capacity available — no major lever displaced.)_ ### Feature Gaps vs Competitors - Offline sync capabilities (available in Tank Mix Calculator but missing here) - Pre-populated chemical/nutrient database (available in Tank Mix Calculator but missing here) ### Outlook: Mixed The agricultural utility market is consolidating around tools that offer offline access and pre-populated data, making manual-entry apps like Fertilizer Calc App increasingly obsolete. The app must transition from a static calculator to a data-rich utility to survive the competitive pressure from established industry players. - 🔴 The 1-star rating on iOS indicates a failure in the core user experience, which will likely accelerate churn if not addressed immediately. - ⚪ Recent updates have focused on stability rather than feature expansion, leaving the app exposed to more aggressive competitors with faster release cadences. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 1/5 | | Total Reviews | 1 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Fertilizer Calc App** (this app) | 1/5 | N/A | Alberto Giambone | | [JobSite King](https://marlvel.ai/intel-report/tools/com-jobsiteking-app) | N/A/5 | N/A | jobsite labs | | [Taranis mobile](https://marlvel.ai/intel-report/business/taranis-mobile) | 5.0/5 | N/A | Taranis | | [GeoPard Agriculture](https://marlvel.ai/intel-report/business/geopard-agriculture) | 5.0/5 | N/A | FlyPard | | [Cropwise Imagery](https://marlvel.ai/intel-report/utilities/cropwise-imagery) | 5.0/5 | Thrilled | Syngenta Digital LTDA | | [Valley Irrigation Run Time](https://marlvel.ai/intel-report/business/valley-irrigation-run-time) | 3.0/5 | N/A | Valmont Industries, Inc. | ## Company Profile - **Developer:** Alberto Giambone - **Website:** [https://www.facebook.com/Fertilizer-Calc-App-411414476266144/](https://www.facebook.com/Fertilizer-Calc-App-411414476266144/) - **Social:** [Instagram](https://www.instagram.com/meta) · [Facebook](https://www.facebook.com/Meta) · [X/Twitter](https://twitter.com/Meta) · [YouTube](https://www.youtube.com/meta) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/fertilizer-calc-app/id1450299266?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.org.agri.urea&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.facebook.com/Fertilizer-Calc-App-411414476266144/) - **Sources:** About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*JobSite King*](https://marlvel.ai/intel-report/tools/com-jobsiteking-app) (jobsite labs) — N/A Rating | N/A Sentiment - [*Taranis mobile*](https://marlvel.ai/intel-report/business/taranis-mobile) (Taranis) — 5.0/5 Rating | N/A Sentiment - [*GeoPard Agriculture*](https://marlvel.ai/intel-report/business/geopard-agriculture) (FlyPard) — 5.0/5 Rating | N/A Sentiment - [*Cropwise Imagery*](https://marlvel.ai/intel-report/utilities/cropwise-imagery) (Syngenta Digital LTDA) — 5.0/5 Rating | Excellent Sentiment - [*Valley Irrigation Run Time*](https://marlvel.ai/intel-report/business/valley-irrigation-run-time) (Valmont Industries, Inc.) — 3.0/5 Rating | N/A Sentiment - [*Farm Feed Protein Mix Cal Pro*](https://marlvel.ai/intel-report/utilities/farm-feed-protein-mix-cal-pro) (Richard Perry) — N/A Rating | N/A Sentiment - [*Tank Mix Calculator*](https://marlvel.ai/intel-report/utilities/tank-mix-calculator) (TapLogic, LLC) — 3.3/5 Rating | N/A Sentiment - [*TankMix*](https://marlvel.ai/intel-report/utilities/tankmix) (Corteva, Inc.) — 5.0/5 Rating | N/A Sentiment - [*Drought Feed Calculator*](https://marlvel.ai/intel-report/business/drought-feed-calculator) (NSW Department of Primary Industries) — 5.0/5 Rating | N/A Sentiment - [*BASF Agro Adviser*](https://marlvel.ai/intel-report/utilities/basf-agro-adviser) (Agro BASF) — 5.0/5 Rating | N/A Sentiment ## 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.
