(Strategic Takeaway) {#so-what} Rock ID - Stone Identifier is an education app. With a 4.33/5 rating from 9.9K reviews, it draws more critical themes in recent reviews than its store average suggests. > **Bottom Line:** The current identification engine fails to meet user expectations, and the 17-month development silence suggests the app is no longer a priority for the publisher. Pivoting to billing transparency would mitigate the immediate churn driving negative sentiment. **Best for:** Geology enthusiasts and amateur rock collectors. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Audit subscription billing flow because users report unauthorized charges after trials → reduce refund surge ### Feature Gaps vs Competitors - Crowd-sourced identification verification (available in Rock Identifier: Stone ID but absent here) ### Outlook: Declining The geology identification market is consolidating around apps with massive, community-verified datasets. Rock ID's reliance on a static AI model and its lack of recent updates leave it exposed to rivals that offer higher accuracy, which will likely lead to further chart erosion. - 🔴 The 17-month development silence indicates the publisher has deprioritized the app, leading to a stagnant feature set and declining user trust. - 🔴 High-frequency billing complaints drive negative sentiment, which compounds the churn pressure already created by inaccurate identification results. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.33/5 | | Total Reviews | 9.9K | | Sentiment | Frustrated (25/100) | | Confidence | High | | Pricing Model | Subscription | | Platforms | iOS & Android | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Rock ID - Stone Identifier** (this app) | 4.33/5 | Frustrated | AIBY | | [PlantNet](https://marlvel.ai/apps/org-plantnetproject-plantnet) | 4.6/5 | N/A | Cirad-France | | [Stellarium Mobile - Star Map](https://marlvel.ai/apps/com-noctuasoftware-stellarium-mobile-plus) | 4.8/5 | N/A | Noctua Software Ltd | | [Plant App: Plant Identifier](https://marlvel.ai/apps/com-scaleup-plantid) | 4.7/5 | n/a | SCALEUP YAZILIM HIZMETLERI | | [Rock Identifier: Stone ID](https://marlvel.ai/apps/com-picturerock-rock) | 4.7/5 | N/A | Next Vision Limited | | [PlantIn: Plant Identifier・Care](https://marlvel.ai/apps/xyz-plantin-app) | 4.6/5 | N/A | Vortemol Limited | ## Company Profile - **Developer:** AIBY - **Website:** [https://aiby.com](https://aiby.com) - **Social:** [Instagram](https://www.instagram.com/aibygroup) · [Facebook](https://www.facebook.com/aibygroup) · [X/Twitter](https://twitter.com/aibygroup) · [LinkedIn](https://www.linkedin.com/company/aibygroup) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/rock-id-stone-identifier/id6469999508?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=rock.identifier.stone.gem.crystal.mineral&hl=en&gl=us) - **Dev Site:** [Official Website](https://aiby.com) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*PlantNet*](https://marlvel.ai/apps/org-plantnetproject-plantnet) (Cirad-France) · 4.6/5 Rating - [*Stellarium Mobile - Star Map*](https://marlvel.ai/apps/com-noctuasoftware-stellarium-mobile-plus) (Noctua Software Ltd) · 4.8/5 Rating - [*Plant App: Plant Identifier*](https://marlvel.ai/apps/com-scaleup-plantid) (SCALEUP YAZILIM HIZMETLERI) · 4.7/5 Rating - [*Rock Identifier: Stone ID*](https://marlvel.ai/apps/com-picturerock-rock) (Next Vision Limited) · 4.7/5 Rating - [*PlantIn: Plant Identifier・Care*](https://marlvel.ai/apps/xyz-plantin-app) (Vortemol Limited) · 4.6/5 Rating - [*Gemstone Identifier °*](https://marlvel.ai/apps/gemstone-identifier-1) (Leonardo Estremadoyro) · 5.0/5 Rating - [*Rock Identifier: Stone Scanner*](https://marlvel.ai/apps/rock-identifier-stone-scanner-1) (Henry Heisenberg Apps, LLC) · 4.6/5 Rating - [*AlgoApp - Flashcards*](https://marlvel.ai/apps/algoapp-flashcards) (AlgoApp Inc) · 4.5/5 Rating - [*Elevate - Brain Training Games*](https://marlvel.ai/apps/elevate-brain-training-games) (The Mind Company) · 4.7/5 Rating - [*Flashcards Deluxe*](https://marlvel.ai/apps/flashcards-deluxe) (OrangeOrApple.com) · 4.5/5 Rating ## Frequently Asked Questions {#faq} ### Is Rock ID accurate for identifying rare minerals? Users report that identification accuracy is inconsistent, often providing incorrect names for common stones. The app relies on an AI engine that currently lacks the community-verified data found in larger competitor apps. ### How does Rock ID compare to Rock Identifier: Stone ID? Rock Identifier: Stone ID offers a significantly larger, crowd-sourced database that improves identification accuracy over time, whereas Rock ID relies on a static AI model that has not received major updates in over a year. ### Are there hidden charges in the subscription? Reviewers frequently report difficulty canceling subscriptions and allege being charged annual fees immediately after starting a trial. Users should carefully review the terms before initiating any trial period. ### What is a free alternative to Rock ID? Users seeking more reliable identification should consider community-driven platforms like PlantNet, which, while focused on plants, demonstrates the identification accuracy achievable through non-profit, community-verified databases. ## 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.
