This pivot reflects an acknowledgment that the 502-day update gap now poses a critical risk to user retention. **Overall trend**: Mixed **Compared at**: 2026-08-16 ### High-impact changes - **[Shifted] Weakness focus: UI friction to Trust erosion** (swot) - **[Shifted] PM Action Item: Pivot to Maintain** (positioning) ### Medium-impact changes - **[Shifted] Opportunity focus: UI to Localization** (swot) ## What's New - **Latest (v1.74, 1 years ago):** Routine maintenance update focused on bug fixes and performance optimization. ## App Momentum (Zombie) {#momentum} - Quiet 16 months, no feature expansion. - Last major release April 2025. > **Cadence:** 1 total versions · 0 majors in last 6 months · 501 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Fetal Weight Calculator is a health & fitness app that is completely free. It holds a 5/5 rating from 1 review. > **Bottom Line:** Fetal Weight Calculator offers a precise, multi-method utility for growth tracking, but the 500-day update gap risks user abandonment as health-data requirements evolve. **Best for:** Expectant parents seeking to track fetal growth measurements against standardized medical growth charts. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Ship a maintenance update to ensure compatibility with current OS standards because the 500-day gap risks app removal → restore user trust ### Outlook: Mixed The market for pregnancy-tracking utilities is shifting toward integrated, high-frequency engagement models that Fetal Weight Calculator currently ignores. Without a return to a regular update cadence, the app will likely see its user base migrate to generalist platforms that offer more frequent feature updates and broader health-tracking capabilities. - 🔴 The 502-day update gap suggests the product is in maintenance mode, which limits its ability to compete with active, feature-rich rivals. - ⚪ The core utility of dual-method calculation remains a valid differentiator for users who specifically require NICHD or WHO-compliant growth tracking. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 5/5 | | Total Reviews | 1 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Fetal Weight Calculator** (this app) | 5/5 | N/A | METKO LABS BILISIM ITHALAT VE IHRACAT TICARET LIMITED SIRKETI | | [GoTall - Height Predictor](https://marlvel.ai/apps/gotall-height-predictor) | 4.5/5 | n/a | Grow Labs LLC | | [Mind - Méditations guidées](https://marlvel.ai/apps/mind-m-ditations-guid-es) | 4.6/5 | Excited | MIND AND CIE | | [Strava: Run, Bike, Walk](https://marlvel.ai/apps/strava-run-bike-walk) | 4.7/5 | n/a | Strava, Inc. | | [Taller AI: Height Maximizer](https://marlvel.ai/apps/taller-ai-height-maximizer) | 4.7/5 | Excited | Leadimize | | [TallerTeen - Grow Taller Now](https://marlvel.ai/apps/tallerteen-grow-taller-now) | 4.7/5 | n/a | Viral App Developement LLC | ## Company Profile - **Developer:** METKO LABS BILISIM ITHALAT VE IHRACAT TICARET LIMITED SIRKETI - **Website:** [https://www.metko.org](https://www.metko.org) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/fetal-weight-calculator/id6470185501?uo=4) - **Dev Site:** [Official Website](https://www.metko.org) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*GoTall - Height Predictor*](https://marlvel.ai/apps/gotall-height-predictor) (Grow Labs LLC) · 4.5/5 Rating - [*Mind - Méditations guidées*](https://marlvel.ai/apps/mind-m-ditations-guid-es) (MIND AND CIE) · 4.6/5 Rating | Positive Sentiment - [*Strava: Run, Bike, Walk*](https://marlvel.ai/apps/strava-run-bike-walk) (Strava, Inc.) · 4.7/5 Rating - [*Taller AI: Height Maximizer*](https://marlvel.ai/apps/taller-ai-height-maximizer) (Leadimize) · 4.7/5 Rating | Positive Sentiment - [*TallerTeen - Grow Taller Now*](https://marlvel.ai/apps/tallerteen-grow-taller-now) (Viral App Developement LLC) · 4.7/5 Rating - [*Activity Tracker・FitnessView*](https://marlvel.ai/apps/activity-tracker-fitnessview) (Funn Media, LLC) · 4.0/5 Rating - [*Avatran Soul*](https://marlvel.ai/apps/avatran-soul) (Avatran GmbH) · N/A Rating - [*Bubblic: Connect with people.*](https://marlvel.ai/apps/bubblic-connect-with-people) (Bubblic Inc.) · 4.6/5 Rating | Positive Sentiment - [*evolum - Meditation & Yoga*](https://marlvel.ai/apps/evolum-meditation-yoga) (Evolum) · 4.7/5 Rating | Positive Sentiment - [*Holoholo: Daily Memories*](https://marlvel.ai/apps/holoholo-daily-memories) (For Pedestrians LLC.) · 4.4/5 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.
