**[Pregnancy + | Tracker App](https://marlvel.ai/intel-report/medical/com-hp-pregnancyiphonelite)** by Philips Digital UK Limited: This is the market leader in pregnancy tracking, directly competing for the same user base seeking gestational monitoring and baby development milestones. - **Key differences:** - Interactive 3D models provide a visual depth that the target app currently lacks entirely. - Massive scale and brand recognition create a significant barrier to entry for smaller utility trackers. - **Where Pregnancy Due Date Calculator wins:** - ✅ Simpler, lightweight interface focused purely on date calculation without overwhelming users with content. - ✅ Direct entry method using last menstrual period or conception date is highly streamlined for quick utility. - **Where Pregnancy + | Tracker App wins:** - ❌ Superior visual engagement through 3D models and high-quality medical illustrations of fetal development. - ❌ Extensive ecosystem of pregnancy tools and community features that drive long-term daily retention. - **Verdict:** The target app cannot compete on content depth; it should pivot to being the fastest, most reliable 'utility-first' calculator to capture users who find the nemesis too bloated. ### Contenders (Strong Challengers) - **[PregTracker: Pregnancy App](https://marlvel.ai/intel-report/medical/pregtracker-pregnancy-app)** by Digital Partner Group GmbH: A direct functional competitor that provides a similar set of tracking tools and baby development information. - Includes a dedicated baby name finder, providing additional utility beyond standard gestational date calculations. - Features a built-in kick counter and contraction timer, consolidating essential labor tools in one place. - **[Pregmate Ovulation Tracker](https://marlvel.ai/intel-report/health-fitness/com-pregmate-app)** by Asteria LLC: Competes at the top of the funnel by capturing users during the conception phase before they transition to pregnancy tracking. - Advanced test reader technology uses computer vision to interpret physical ovulation test results automatically. - Includes menopause (FSH) test scanning, expanding the user lifecycle beyond just pregnancy and conception. - **[BabyTime](https://marlvel.ai/intel-report/health-fitness/babytime)** by Bucky Ltd: Directly competes by offering a comprehensive suite of post-conception tools including contraction timers and multi-caregiver sync. - Offers Wear OS support, allowing users to track contractions and activity directly from their wrist. - Multi-caregiver sync functionality enables partners to participate in the tracking process, increasing platform stickiness. - **[Mindful Birth](https://marlvel.ai/intel-report/medical/com-mymindfulmidwife-www)** by The Mindful Birth Group limited: Competes by targeting the emotional and psychological wellness aspect of pregnancy rather than just the clinical tracking. - Integrates specialized mindful relaxation audios which differentiate it from purely data-driven pregnancy calculators. - Focuses on birth preference customization, offering a niche value proposition for expectant parents. ### Peers (What They Do Better) - **[Christian Hypnobirthing](https://marlvel.ai/intel-report/medical/uk-co-christianhypnobirthing-iosoverview)** by Gather Pty Ltd: Targets a specific demographic segment within the pregnancy space through faith-based birth preparation. - Curates scripture-based audio tracks that align with the specific values of their target user base. - Features positive birth stories that build community trust through shared religious and personal experiences. - **[Poppy Seed Health](https://marlvel.ai/intel-report/health-fitness/poppy-seed-health)** by Poppy Seed Health: Competes by offering human-centric support services that complement the automated tracking provided by the target app. - Provides 24/7 on-demand text support from advocates, creating a high-touch service model for users. - Includes a Medicaid support program, significantly expanding accessibility for underserved expectant populations. -

Provides physical therapy-led content specifically for pelvic floor and abdominal health during and after pregnancy. - Offers personalized strength training programs that cater to the specific physiological needs of pregnant users. ### New Kids on the Block (What's Innovative) - **[Vision Tracker – Myopia](https://marlvel.ai/intel-report/health-fitness/vision-tracker-myopia)** by 跃松 邬: While focused on vision, it competes for the same 'health tracking' screen time and user attention. - Provides automated AI insights and PDF reporting for clinical health trends, mimicking professional medical monitoring. - **[TinyVitals :Track.Grow.Protect](https://marlvel.ai/intel-report/medical/tinyvitals-track-grow-protect)** by Murugan Ambigapathy: A new entrant focusing on the transition from pregnancy to early childhood health management. - Utilizes AI-powered record storage to simplify the management of complex pediatric health documents. ## What's New - **Latest (v1.1.1, 4 months ago):** General app performance optimization. ## App Momentum (Zombie) {#momentum} - Maintains utility-focused feature set. - Last major update January 2026. > **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 an established medical app that is free with in-app purchases. > **Bottom Line:** The app succeeds as a fast utility tool, but it lacks the retention loops of market leaders, so the PM should prioritize adding essential labor-tracking tools to increase session frequency. **Best for:** Expectant parents seeking simple, date-based tracking tools for pregnancy milestones. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [MEDIUM IMPACT] Ship a contraction timer because it is a high-utility tool missing from the current feature set → increase session frequency — *Competitors like PregTracker include labor tools to consolidate utility.* _(trade-off: deprioritize Pause the zodiac sign prediction update — it is a low-utility differentiator.)_ ### Feature Gaps vs Competitors - Interactive 3D fetal models (available in Pregnancy +) - Contraction timer (available in PregTracker) - Multi-caregiver sync (available in BabyTime) ### Outlook: Stable The pregnancy tracking market is consolidating around high-engagement, content-rich platforms. This app remains stable as a simple utility, but it must add core labor tools to prevent user migration to more comprehensive competitors. - ⚪ The app maintains a steady utility-first focus, but the lack of feature expansion leaves it vulnerable to content-rich competitors. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | 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 | N/A | Webtoweb | | [Pregnancy + | Tracker App](https://marlvel.ai/intel-report/medical/com-hp-pregnancyiphonelite) | 4.8/5 | Thrilled | Philips Digital UK Limited | | [Christian Hypnobirthing](https://marlvel.ai/intel-report/medical/uk-co-christianhypnobirthing-iosoverview) | 4.9/5 | Thrilled | Gather Pty Ltd | | [Mulier](https://marlvel.ai/intel-report/health-fitness/com-mulierapp-mulier) | 5.0/5 | N/A | Mulier | | [Mindful Birth](https://marlvel.ai/intel-report/medical/com-mymindfulmidwife-www) | 4.9/5 | N/A | The Mindful Birth Group limited | | [PregTracker: Pregnancy App](https://marlvel.ai/intel-report/medical/pregtracker-pregnancy-app) | 4.9/5 | Thrilled | Digital Partner Group GmbH | ## 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 - [*Pregnancy + | Tracker App*](https://marlvel.ai/intel-report/medical/com-hp-pregnancyiphonelite) (Philips Digital UK Limited) — 4.8/5 Rating | Excellent Sentiment - [*Christian Hypnobirthing*](https://marlvel.ai/intel-report/medical/uk-co-christianhypnobirthing-iosoverview) (Gather Pty Ltd) — 4.9/5 Rating | Excellent Sentiment - [*Mulier*](https://marlvel.ai/intel-report/health-fitness/com-mulierapp-mulier) (Mulier) — 5.0/5 Rating | N/A Sentiment - [*Mindful Birth*](https://marlvel.ai/intel-report/medical/com-mymindfulmidwife-www) (The Mindful Birth Group limited) — 4.9/5 Rating | N/A Sentiment - [*PregTracker: Pregnancy App*](https://marlvel.ai/intel-report/medical/pregtracker-pregnancy-app) (Digital Partner Group GmbH) — 4.9/5 Rating | Excellent Sentiment - [*TinyVitals :Track.Grow.Protect*](https://marlvel.ai/intel-report/medical/tinyvitals-track-grow-protect) (Murugan Ambigapathy) — N/A Rating | N/A Sentiment - [*BabyTime*](https://marlvel.ai/intel-report/health-fitness/babytime) (Bucky Ltd) — 4.6/5 Rating | Excellent Sentiment - [*Poppy Seed Health*](https://marlvel.ai/intel-report/health-fitness/poppy-seed-health) (Poppy Seed Health) — 4.9/5 Rating | Positive Sentiment - [*Vision Tracker – Myopia*](https://marlvel.ai/intel-report/health-fitness/vision-tracker-myopia) (跃松 邬) — N/A Rating | N/A Sentiment - [*Birth Log - Midwife & OBGYN*](https://marlvel.ai/intel-report/medical/birth-log-midwife-obgyn) (Jordan Zeleny) — 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.
