The app has not received a major feature update in over 149 days, signaling a maintenance-mode posture. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free app download, Requires paid King-Devick Online account for full functionality - **Analysis:** The app acts as a mobile client for a B2B subscription service, gating all utility behind an existing enterprise account. ## SWOT Analysis {#swot} **Core Strengths:** - Offline-first assessment architecture ensures continuity of care in remote field environments - Institutional B2B portal structure creates high switching costs for existing health service contracts **Growth Levers:** - Expansion into non-contact sports or school-based wellness programs increases annual baseline test volume ## What's New - **Latest (vv5.6, 4 months ago):** Maintenance update focused on bug fixes and performance improvements. ## App Momentum (Maintenance) {#momentum} - Ships maintenance updates only. - Last major release over 4 months ago. > **Cadence:** 1 total versions · 0 majors in last 6 months · 149 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} King-Devick Test is a health & fitness app that is free with in-app purchases. It holds a 5/5 rating from 2 reviews. > **Bottom Line:** King-Devick Test secures its position through institutional B2B lock-in, but the lack of feature expansion risks stagnation against more agile digital health entrants. **Best for:** Parents, coaches, athletic trainers, and medical professionals managing concussion screening for athletes aged 5 and older. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit offline sync logic because the app relies on field-based utility → maintain assessment reliability ### Outlook: Stable The market for digital concussion screening is consolidating around institutional partnerships that offer longitudinal baseline tracking. King-Devick Test is advantaged by its existing B2B contract structure, but the lack of recent feature investment leaves it exposed to competitors that might offer more integrated, faster screening workflows. - ⚪ The app remains in a maintenance-only release cadence, which prioritizes protocol stability over new feature expansion for institutional clients. - 🟢 The offline-first assessment capability continues to serve the core sideline use case, ensuring the app remains functional in remote field environments. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 5/5 | | Total Reviews | 2 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **King-Devick Test** (this app) | 5/5 | N/A | King-Devick Test, LLC | | [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:** King-Devick Test, LLC ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/king-devick-test/id1033607954?uo=4) - **Sources:** 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 | Excellent 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.
