**[MKS Beton](https://marlvel.ai/apps/com-mksbetongroup-mymksbeton)** by MKS BETON LLC: While focused on construction materials, it competes for the same utility-app user base by offering specialized material calculators. - Provides a bilingual interface that expands accessibility for international users in the construction and material sector. - **[Farm Feed Protein Mix Cal Pro](https://marlvel.ai/apps/farm-feed-protein-mix-cal-pro)** by Richard Perry: This newcomer targets the same agricultural utility market by focusing on specialized feed mix and protein balancing calculations. - Focuses exclusively on balancer feed integration to simplify complex nutritional calculations for livestock producers. ## What's New - **Latest (v1.0.1, 14 years ago):** Added history deletion and integrated added chemicals into carrier water calculations. ## App Momentum (Zombie) {#momentum} - No major feature releases in 2025. - Last store update over 370 days ago. > **Cadence:** 5 total versions · 0 majors in last 6 months · 293 days since last update · 307 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Tank Mix Calculator is an utilities app that is free with in-app purchases. With a 2.75/5 rating from 237 reviews, it faces significant user friction. > **Bottom Line:** Tank Mix Calculator provides a high-utility chemical database, but the current technical instability blocks basic access, so the PM must prioritize a stability sprint to prevent the total collapse of the FarmLogic acquisition funnel. **Best for:** Farmers and agricultural operators requiring field record-keeping and chemical mixing calculations. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Rebuild terms-of-service screen because it blocks new user access → restore install-to-first-use conversion ### Feature Gaps vs Competitors - Spray tip recommendation engine (available in SpraySelect but missing here) ### Outlook: Declining The agricultural utility market is consolidating around apps that offer both calculation and hardware-specific optimization. Tank Mix Calculator's lack of development leaves it exposed to rivals like SpraySelect, which will continue to drain the user base until the core usability bugs are addressed. - 🔴 Critical usability regressions in the latest version (terms-screen lock, unit-toggle failure) erode the daily active habit, which compounds the rating drag. - 🔴 The 373-day update gap signals the app is in maintenance mode, leaving it vulnerable to rivals with higher release cadences. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2.75/5 | | Total Reviews | 237 | | Sentiment | Frustrated (25/100) | | Confidence | High | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Tank Mix Calculator** (this app) | 2.75/5 | Frustrated | TapLogic, LLC | | [MKS Beton](https://marlvel.ai/apps/com-mksbetongroup-mymksbeton) | N/A/5 | N/A | MKS BETON LLC | | [db.Mobil App](https://marlvel.ai/apps/de-bhzp-dbmobil) | 4.1/5 | N/A | BHZP GmbH | | [Fertilizer Calc App](https://marlvel.ai/apps/fertilizer-calc-app) | 1.0/5 | N/A | Alberto Giambone | | [xarvio® FIELD MANAGER](https://marlvel.ai/apps/xarvio-field-manager) | 4.1/5 | N/A | BASF Digital Farming GmbH | | [FieldNET](https://marlvel.ai/apps/fieldnet) | 3.9/5 | N/A | Lindsay Irrigation Solutions LLC | ## Company Profile - **Developer:** TapLogic, LLC - **Website:** [https://www.farmlogic.com](https://www.farmlogic.com) - **Social:** [Facebook](https://www.facebook.com/TapLogic) · [X/Twitter](https://twitter.com/taplogic) · [YouTube](https://www.youtube.com/channel/UCoaD18juEXoBNxQzoXRrlSg) · [LinkedIn](https://www.linkedin.com/company/taplogic-llc-) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/tank-mix-calculator/id464313025?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=air.com.taplogic.tankmixcalculator&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.farmlogic.com) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*MKS Beton*](https://marlvel.ai/apps/com-mksbetongroup-mymksbeton) (MKS BETON LLC) · N/A Rating - [*db.Mobil App*](https://marlvel.ai/apps/de-bhzp-dbmobil) (BHZP GmbH) · 4.1/5 Rating - [*Fertilizer Calc App*](https://marlvel.ai/apps/fertilizer-calc-app) (Alberto Giambone) · 1.0/5 Rating - [*xarvio® FIELD MANAGER*](https://marlvel.ai/apps/xarvio-field-manager) (BASF Digital Farming GmbH) · 4.1/5 Rating - [*FieldNET*](https://marlvel.ai/apps/fieldnet) (Lindsay Irrigation Solutions LLC) · 3.9/5 Rating - [*Valley Irrigation Run Time*](https://marlvel.ai/apps/valley-irrigation-run-time) (Valmont Industries, Inc.) · 3.0/5 Rating - [*Lely Control*](https://marlvel.ai/apps/lely-control) (Lely Industries N.V.) · 3.7/5 Rating - [*Farm Feed Protein Mix Cal Pro*](https://marlvel.ai/apps/farm-feed-protein-mix-cal-pro) (Richard Perry) · N/A Rating - [*TankMix*](https://marlvel.ai/apps/tankmix) (Corteva, Inc.) · 5.0/5 Rating - [*Drought Feed Calculator*](https://marlvel.ai/apps/drought-feed-calculator) (NSW Department of Primary Industries) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Tank Mix Calculator free to use?
