The lack of updates for over 900 days signals a maintenance-only posture that limits its competitive reach against active health-tracking platforms. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is distributed as a free utility with no visible monetization, subscription, or in-app purchase hooks. ## SWOT Analysis {#swot} **Core Strengths:** - Privacy-centric design (no sign-in) lowers entry friction **Growth Levers:** - Adding local data-persistence for trend tracking ## Recent Changes (v2 → v3) {#recent-changes} The app's competitive assessment has shifted from a passive maintenance-mode observation to an active identification of feature gaps, specifically the lack of longitudinal data tracking compared to integrated health platforms. **Overall trend**: Stable **Compared at**: 2026-08-21 ### High-impact changes - **[Added] New SWOT Strategic Focus** (swot) ### Medium-impact changes - **[Shifted] Narrative Focus Shift** (positioning) - **[Shifted] PM Action Item Decision** (positioning) ## What's New - **Latest (v1.0.1, 2 years ago):** General stability improvements. ## App Momentum (Zombie) {#momentum} - Maintenance-mode, no updates for 911 days. - Static feature set since initial release. > **Cadence:** 1 total versions · 0 majors in last 6 months · 911 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} BMI - Body Mass Index Calc is a health & fitness app that is completely free. > **Bottom Line:** BMI - Body Mass Index Calc serves as a functional, private utility, but the lack of development since early 2024 leaves it vulnerable to feature-rich alternatives that sync with broader health platforms. **Best for:** Individuals seeking a simple, private tool to track body mass index without account registration. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit local storage requirements because the 911-day update gap suggests a lack of data persistence → unlock user retention ### Outlook: Declining The health-utility market is consolidating around platforms that offer automated data syncing and longitudinal trend analysis. BMI - Body Mass Index Calc remains static, which exposes it to churn as users prioritize tools that provide actionable health insights over simple, one-off calculations. - 🔴 The 911-day update gap indicates the tool is in maintenance-mode, which prevents it from competing with modern, feature-rich health platforms. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **BMI - Body Mass Index Calc** (this app) | N/A/5 | N/A | Przemyslaw Skowronek | | [GoTall - Height Predictor](https://marlvel.ai/apps/gotall-height-predictor) | 4.6/5 | 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:** Przemyslaw Skowronek - **Website:** [https://skylarks.io/apps/bmi](https://skylarks.io/apps/bmi) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/bmi-body-mass-index-calc/id6477485217?uo=4) - **Dev Site:** [Official Website](https://skylarks.io/apps/bmi) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*GoTall - Height Predictor*](https://marlvel.ai/apps/gotall-height-predictor) (Grow Labs LLC) · 4.6/5 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.
