(Strategic Takeaway) {#so-what} Carb Unit Diary for Diabetics is a medical app that is free with in-app purchases. It holds a 4.17/5 rating from 24 reviews. > **Bottom Line:** Carb Unit Diary for Diabetics serves a specific nutrition-tracking need, but the lack of updates over the last two years leaves it vulnerable to competitors offering modern glucose-trend analysis. Prioritizing a feature refresh is necessary to prevent total user attrition to more active, data-rich alternatives. **Best for:** Individuals managing diabetes who require a mobile solution for tracking carbohydrate intake and physical activity. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit the codebase for a minimal feature refresh because the 793-day update gap is a terminal churn risk → restore user trust ### Feature Gaps vs Competitors - A1C tracking and visual progress reporting (available in Blood Sugar Glucose Tracker but missing here) ### Outlook: Declining The medical management market is consolidating around high-cadence platforms that integrate prescription logistics and advanced trend analysis. Carb Unit Diary for Diabetics is currently exposed due to its lack of development, and it will likely lose its remaining user base to more active competitors by the end of the year. - 🔴 The 793-day update gap indicates the app is in maintenance mode, which will lead to inevitable user churn as competitors iterate on core features. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.17/5 | | Total Reviews | 24 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 4 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Carb Unit Diary for Diabetics** (this app) | 4.17/5 | N/A | Jommi UG (haftungsbeschrankt) | | [NimbleRx](https://marlvel.ai/apps/com-nimblerx-nimblerx) | 4.9/5 | Excited | NimbleRx | | [Hickey’s Pharmacy App](https://marlvel.ai/apps/ie-hickeys-live) | 4.0/5 | N/A | Hickey’s Pharmacy | | [Dose Medbox](https://marlvel.ai/apps/com-daralabs-dose-application) | 4.8/5 | N/A | Dose Medbox | | [Ozempic® Suomi](https://marlvel.ai/apps/com-novonordisk-semafinland) | 3.6/5 | N/A | NovoNordisk A/S | | [Walmart Pharmacy App](https://marlvel.ai/apps/ca-walmart-pharmacy) | 3.2/5 | N/A | Walmart | ## Company Profile - **Developer:** Jommi UG (haftungsbeschrankt) - **Website:** [https://www.jommi.de](https://www.jommi.de) - **Social:** [Instagram](https://www.instagram.com/jommi.apps) · [Facebook](https://www.facebook.com/jommi.apps) · [TikTok](https://www.tiktok.com/@jommi.apps) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/carb-unit-diary-for-diabetics/id1460366245?uo=4) - **Dev Site:** [Official Website](https://www.jommi.de) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*NimbleRx*](https://marlvel.ai/apps/com-nimblerx-nimblerx) (NimbleRx) · 4.9/5 Rating | Positive Sentiment - [*Hickey’s Pharmacy App*](https://marlvel.ai/apps/ie-hickeys-live) (Hickey’s Pharmacy) · 4.0/5 Rating - [*Dose Medbox*](https://marlvel.ai/apps/com-daralabs-dose-application) (Dose Medbox) · 4.8/5 Rating - [*Ozempic® Suomi*](https://marlvel.ai/apps/com-novonordisk-semafinland) (NovoNordisk A/S) · 3.6/5 Rating - [*Walmart Pharmacy App*](https://marlvel.ai/apps/ca-walmart-pharmacy) (Walmart) · 3.2/5 Rating - [*Exoda Food Calories Recipes*](https://marlvel.ai/apps/exoda-food-calories-recipes) (Tobias Stephan) · N/A Rating - [*Gout Diet - Acid Uric Table*](https://marlvel.ai/apps/gout-diet-acid-uric-table) (ngo phong) · 4.4/5 Rating - [*Took It - Pill Log*](https://marlvel.ai/apps/took-it-pill-log) (HIROTO TSUTSUSHIMA) · N/A Rating - [*Luka – Blood Glucose Readings*](https://marlvel.ai/apps/luka-blood-glucose-readings) (Pitou Technologies, LLC) · 4.6/5 Rating - [*WellView*](https://marlvel.ai/apps/wellview) (WellDyneRx) · 2.9/5 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.
