Utilizes facial analysis tracking to predict fertility windows, offering a unique biometric data input method - Focuses specifically on ovulation probability, serving a distinct user intent compared to pregnancy tracking ### Peers (What They Do Better) - **[First Trimester Bleeding](https://marlvel.ai/apps/first-trimester-bleeding)** by Joshua D. steinberg: This app addresses specific medical concerns during early pregnancy, overlapping with this app's gestational age tracking. - Provides specialized diagnostic protocols and viability assessment tools for high-risk pregnancy scenarios - Focuses on clinical management guidance rather than general pregnancy countdown or weight tracking -

Integrates AI-powered record storage for vaccination management and symptom logging to simplify pediatric health tracking ## What's New - **Latest (v1.1.1, 4 months ago):** General app performance optimization. ## App Momentum (Zombie) {#momentum} - Quiet 4 months, bug fixes only. - Last major release May 2023. > **Cadence:** 1 total versions · 0 majors in last 6 months · 136 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Pregnancy Due Date Calculator is a market-leading medical app that is free with in-app purchases. > **Bottom Line:** Pregnancy Due Date Calculator remains a functional, lightweight utility, but its lack of feature expansion leaves it exposed to rivals with deeper retention loops. Pivoting toward specialized clinical exports would unlock value for users without requiring a full-scale content strategy. **Best for:** Expectant parents seeking simple, date-based tracking tools for pregnancy milestones. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit ad-placement frequency because users find the interface simple and intuitive → maintain high-frequency impression volume. ### Feature Gaps vs Competitors - 3D interactive growth visualizations (available in The Bump but absent here) ### Outlook: Stable The pregnancy tracking market is consolidating around platforms that offer integrated registry and community features, pushing single-purpose calculators into a secondary utility role. Pregnancy Due Date Calculator must lean into its speed and simplicity to avoid being displaced by these comprehensive rivals, as the current maintenance-only cadence offers no path to growth. - 🔴 The four-month silence in development suggests a maintenance-only posture, which limits the ability to compete with rivals shipping frequent feature updates. - ⚪ Positive sentiment regarding the simple interface provides a stable foundation, provided the app remains a lightweight alternative to content-heavy competitors. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Sentiment | Excited (75/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | Android | | Key Features | 4 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Pregnancy Due Date Calculator** (this app) | N/A/5 | Excited | Webtoweb | | [Contraction Timer: Labora](https://marlvel.ai/apps/panittha-app-contractiontimer) | 5.0/5 | N/A | Panittha Suwannajang | | [Clínica Medrano](https://marlvel.ai/apps/es-gestamed-medrano) | 5.0/5 | N/A | Gooveris Software | | [Simple Birth Plan](https://marlvel.ai/apps/com-waytoplan-mybirthplan) | 1.0/5 | N/A | Jacob Hendrik Huisman | | [Mindful Birth](https://marlvel.ai/apps/com-mymindfulmidwife-www) | 4.9/5 | N/A | The Mindful Birth Group limited | | [The Bump: Baby & Pregnancy App](https://marlvel.ai/apps/the-bump-baby-pregnancy-app) | 4.9/5 | Excited | The Knot Inc. | ## Company Profile - **Developer:** Webtoweb - **Website:** [https://www.webtoweb.fr](https://www.webtoweb.fr) ## Data Sources & Links - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=due.date.calculator&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.webtoweb.fr) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Contraction Timer: Labora*](https://marlvel.ai/apps/panittha-app-contractiontimer) (Panittha Suwannajang) · 5.0/5 Rating - [*Clínica Medrano*](https://marlvel.ai/apps/es-gestamed-medrano) (Gooveris Software) · 5.0/5 Rating - [*Simple Birth Plan*](https://marlvel.ai/apps/com-waytoplan-mybirthplan) (Jacob Hendrik Huisman) · 1.0/5 Rating - [*Mindful Birth*](https://marlvel.ai/apps/com-mymindfulmidwife-www) (The Mindful Birth Group limited) · 4.9/5 Rating - [*The Bump: Baby & Pregnancy App*](https://marlvel.ai/apps/the-bump-baby-pregnancy-app) (The Knot Inc.) · 4.9/5 Rating | Positive Sentiment - [*OB Pregnancy Wheel Made Easy*](https://marlvel.ai/apps/ob-pregnancy-wheel-made-easy) (Medicon Apps) · 5.0/5 Rating - [*Easy Ovulation - My Fertility*](https://marlvel.ai/apps/easy-ovulation-my-fertility) (Caramba App Development) · 4.7/5 Rating - [*First Trimester Bleeding*](https://marlvel.ai/apps/first-trimester-bleeding) (Joshua D. steinberg) · 5.0/5 Rating - [*TinyVitals :Track.Grow.Protect*](https://marlvel.ai/apps/tinyvitals-track-grow-protect) (Murugan Ambigapathy) · N/A Rating - [*BabyTime*](https://marlvel.ai/apps/babytime) (Bucky Ltd) · 4.6/5 Rating | Excellent 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.
