US Market. No publisher influence. > **Key Insight:** Crystal Index is a reference app by Lunar Computing, Inc. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Reference | | **Developer** | Lunar Computing, Inc | | **Pricing** | Freemium | | **Platforms** | iOS | | **Confidence** | Low (0.2/1.0) | | **Data Age** | 51d | ## Metadata & Market Performance - **Publisher:** Lunar Computing, Inc - **Category:** Reference - **Target Audience:** Crystal collectors and enthusiasts seeking a digital tool for identification, study, and inventory management. - **Platforms:** iOS - **Version Reviewed:** 1.1.0 - **Report Date:** 2026-09-24 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.2/1.0) - **App Store ID (iOS):** 6760981052 - **Bundle ID:** app.lunary.crystalindex - **Data Window:** Analysis based on signals collected up to 2026-09-24 ## Executive Snapshot **What it is:** Crystal Index is a reference guide and collection manager for crystals, offering photo-based identification and inventory tracking on iOS. **Why users hire it:** The tool removes the cognitive friction of manual cataloging for collectors, replacing fragmented physical notes with a unified, searchable digital library. ## App DNA (Features & Intent) - **[Differentiator] AI Crystal Identification:** Analyzes photo input for color, structure, and texture to provide ranked identification matches. * *User Intent:* Users are driven by competitive achievement and recognition. - **[Standard] Personal Collection Manager:** Catalogues owned crystals with photo library, origin tracking, and custom organization. * *User Intent:* Users value self-expression and personalized experiences. - **[Differentiator] Background Removal:** Automated image processing to isolate crystal photos for a clean library aesthetic. * *User Intent:* Users seek enhanced value through premium features. ## Market Position {#market-position} Crystal Index operates in the Reference category, maintaining a 4+ content rating. The current release cadence (67-day average) suggests a focus on feature-gated monetization rather than rapid iteration. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free tier: Full reference guide, five saved crystals, five identifications., Premium tier: £4.99/month or £39.99/year for unlimited features. - **Analysis:** Usage-based gates on identification and collection size drive conversion to the annual plan. ## SWOT Analysis {#swot} **Core Strengths:** - AI-powered identification creates a functional barrier against static reference guides. - CloudKit integration ensures data persistence across user devices. **Growth Levers:** - Localized encyclopaedia content could capture niche regional collector segments. ## What's New - **Latest (v1.1.0, 5 days ago):** Introduced a free trial for AI crystal identification and relocated the camera to the Collection view. ## App Momentum (Maintenance) {#momentum} - Shipped AI-powered crystal identification. - Integrated camera into collection view. - Ships ~2 releases per year. > **Cadence:** 2 total versions · 1 majors in last 6 months · 5 days since last update · 67 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Crystal Index is a reference app that is free with in-app purchases. > **Bottom Line:** Crystal Index effectively uses AI identification to gate premium value, but the restrictive free tier limits the user base needed to sustain long-term growth. Increasing the free-tier utility would expand the funnel, allowing the premium conversion rate to scale with the total user volume. **Best for:** Crystal collectors and enthusiasts seeking a digital tool for identification, study, and inventory management. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Raise free collection limit to ten items because current five-item cap restricts the acquisition funnel → increase long-term retention ### Outlook: Stable The reference category is shifting toward AI-integrated utility, and Crystal Index is positioned to capture high-intent users via its identification tool. Sustaining this position requires balancing the free-tier acquisition funnel against the premium monetization gates to ensure the user base grows alongside the revenue. - 🟢 The latest release adds AI-powered identification, which strengthens the premium value proposition and provides a clear conversion path for power users. - ⚪ A 67-day average update cadence indicates a maintenance-focused development cycle rather than an aggressive feature-expansion strategy. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Crystal Index** (this app) | N/A/5 | N/A | Lunar Computing, Inc | | [올어바웃성경](https://marlvel.ai/apps/com-allabout-bibleapp) | 5.0/5 | N/A | Gilju Lee | | [Hallow: Prayer & Meditation](https://marlvel.ai/apps/hallow-prayer-meditation) | 4.7/5 | n/a | Hallow, Inc. | | [고려대 한국어 속담 사전](https://marlvel.ai/apps/app--428) | N/A/5 | N/A | DaolSoft, Co., Ltd. | | [우리말 의학사전](https://marlvel.ai/apps/app--427) | N/A/5 | N/A | DaolSoft, Co., Ltd. | | [공인중개사 용어사전](https://marlvel.ai/apps/app--429) | N/A/5 | N/A | DaolSoft, Co., Ltd. | ## Company Profile - **Developer:** Lunar Computing, Inc - **Website:** [https://crystalindex.co.uk](https://crystalindex.co.uk) ## Data Sources & Links - **App Store ID:** 6760981052 - **Dev Site:** [Official Website](https://crystalindex.co.uk) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*올어바웃성경*](https://marlvel.ai/apps/com-allabout-bibleapp) (Gilju Lee) · 5.0/5 Rating - [*Hallow: Prayer & Meditation*](https://marlvel.ai/apps/hallow-prayer-meditation) (Hallow, Inc.) · 4.7/5 Rating - [*고려대 한국어 속담 사전*](https://marlvel.ai/apps/app--428) (DaolSoft, Co., Ltd.) · N/A Rating - [*우리말 의학사전*](https://marlvel.ai/apps/app--427) (DaolSoft, Co., Ltd.) · N/A Rating - [*공인중개사 용어사전*](https://marlvel.ai/apps/app--429) (DaolSoft, Co., Ltd.) · N/A Rating - [*브리태니커 콘사이스 백과사전*](https://marlvel.ai/apps/app--425) (DaolSoft, Co., Ltd.) · N/A Rating - [*100 Radio Hrvatska (HR) : Vijesti, glazba, Nogomet*](https://marlvel.ai/apps/100-radio-hrvatska-hr-vijesti-glazba-nogomet) (Thomas Gesland) · 1.0/5 Rating - [*100 US Citizenship Test Questions 2017*](https://marlvel.ai/apps/100-us-citizenship-test-questions-2017) (Andrey Fetisov) · 4.7/5 Rating - [*١٠١ پرسیار لە زانستی قورئان*](https://marlvel.ai/apps/app--952) (Abdulwahab F.
