US Market. No publisher influence. > **Key Insight:** AR Needle Guide is a medical app by Kazufumi Suzuki. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Medical | | **Developer** | Kazufumi Suzuki | | **Pricing** | Free | | **Platforms** | iOS | | **Confidence** | Low (0.3/1.0) | | **Data Age** | 30d | ## Metadata & Market Performance - **Publisher:** Kazufumi Suzuki - **Category:** Medical - **Target Audience:** Medical professionals and researchers conducting studies on image-guided procedures and AR/MR technology. - **Platforms:** iOS - **Version Reviewed:** 3.6 - **Report Date:** 2026-10-15 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.3/1.0) - **App Store ID (iOS):** 1516215649 - **Bundle ID:** com.TWIns.ARGuide - **Data Window:** Analysis based on signals collected up to 2026-10-15 ## Executive Snapshot **What it is:** AR Needle Guide is an augmented reality software for CT-guided procedures, designed for medical researchers to align virtual tools with physical space on iOS devices. **Why users hire it:** The app removes the need for manual, contact-based angle measurement during biopsy procedures by providing real-time AR guidance anchored to CT scanner laser apertures. ## App DNA (Features & Intent) - **[Differentiator] AR Coordinate System:** Establishes a spatial anchor using laser apertures on CT scanners to align virtual tools with physical space. - **[Differentiator] Virtual Protractor:** Displays a movable, tiltable protractor in the CT scan plane to assist in determining puncture positions. * *User Intent:* Users seek enhanced value through premium features. - **[Differentiator] Needle Tracking:** Uses the device camera to recognize specific biopsy needles and display tilt and roll angles in real time. * *User Intent:* Users want visibility into their own performance and progress. ## Market Position {#market-position} AR Needle Guide functions as a specialized research utility with no commercial chart presence. Its positioning relies on technical integration with CT hardware rather than mass-market adoption. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The application is provided as a free research tool with no commercial monetization or in-app purchases. ## SWOT Analysis {#swot} **Core Strengths:** - Technical authority in image-guided procedures established through research-based positioning **Growth Levers:** - Expansion into broader clinical training modules could increase utility beyond research settings ## What's New - **Latest (v3.6, 2 years ago):** Upgraded to AR Foundation 5 and XR Interaction Toolkit for improved augmented reality capabilities. ## App Momentum (Zombie) {#momentum} - Quiet 31 months, no feature expansion - Last major release March 2024 > **Cadence:** 1 total versions · 1 majors in last 6 months · 944 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} AR Needle Guide is a medical app that is completely free. > **Bottom Line:** AR Needle Guide serves as a niche research tool, but the lack of updates since early 2024 limits its reliability for clinical use. Maintaining the existing codebase is the only viable path until the developer commits to a new feature cycle. **Best for:** Medical professionals and researchers conducting studies on image-guided procedures and AR/MR technology. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit compatibility with latest iOS versions because the app has been silent for 31 months → ensure core AR functionality remains stable ### Outlook: Declining The market for AR-assisted medical guidance is shifting toward integrated, vendor-supported solutions rather than standalone research tools. AR Needle Guide remains exposed due to its stagnant development, which will likely lead to obsolescence as iOS hardware and AR frameworks evolve. - 🔴 The 945-day gap since the last update indicates the project is in maintenance mode, which erodes trust for clinical users. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **AR Needle Guide** (this app) | N/A/5 | N/A | Kazufumi Suzuki | | [BabyMeasure: Growth Tracker](https://marlvel.ai/apps/babymeasure-growth-tracker) | N/A/5 | N/A | Emre HAMURCU | | [Lace Pro](https://marlvel.ai/apps/lace-pro) | 4.6/5 | Excited | Neurotone AI | | [Medical Abbreviations: Quick](https://marlvel.ai/apps/medical-abbreviations-quick) | 4.0/5 | Excited | VLR Software | | [Nursing Home Check](https://marlvel.ai/apps/nursing-home-check) | 3.7/5 | N/A | Alona Nesterenko | | [VetCore: Pet Health Records](https://marlvel.ai/apps/vetcore-pet-health-records) | N/A/5 | N/A | Dmitriy Motorin | ## Company Profile - **Developer:** Kazufumi Suzuki - **Website:** [https://sites.google.com/view/arneedleguide/privacy-policy](https://sites.google.com/view/arneedleguide/privacy-policy) ## Data Sources & Links - **App Store ID:** 1516215649 - **Dev Site:** [Official Website](https://sites.google.com/view/arneedleguide/privacy-policy) - **Sources:** Developer website content, About us / company information, App store metadata. ## Related Intel Reports - [*BabyMeasure: Growth Tracker*](https://marlvel.ai/apps/babymeasure-growth-tracker) (Emre HAMURCU) · N/A Rating - [*Lace Pro*](https://marlvel.ai/apps/lace-pro) (Neurotone AI) · 4.6/5 Rating | Positive Sentiment - [*Medical Abbreviations: Quick*](https://marlvel.ai/apps/medical-abbreviations-quick) (VLR Software) · 4.0/5 Rating | Positive Sentiment - [*Nursing Home Check*](https://marlvel.ai/apps/nursing-home-check) (Alona Nesterenko) · 3.7/5 Rating - [*VetCore: Pet Health Records*](https://marlvel.ai/apps/vetcore-pet-health-records) (Dmitriy Motorin) · N/A Rating - [*필잇 - 약 알림 및 복용 기록*](https://marlvel.ai/apps/app--35) (Hansub Yoo) · N/A Rating - [*레어노트 - 암·희귀질환 정보*](https://marlvel.ai/apps/app--629) (LifeX, Inc.) · 5.0/5 Rating - [*창고형약국 약값체크*](https://marlvel.ai/apps/com-hiddenwave-yakcheck) (Lowkeybase) · N/A Rating - [*용인세브란스병원*](https://marlvel.ai/apps/com-severance-newys) (Yonsei University Health System) · 1.9/5 Rating - [*1001Doktor*](https://marlvel.ai/apps/com-binbirdoktor-binbirdoktor) (1001Doktor Ltd.
