Tutorial for OC is exposed due to its stagnant update cadence, which will likely lead to further rating erosion as the content becomes increasingly disconnected from current development practices. - 🔴 The three-year update gap suggests the developer has abandoned active maintenance, which will accelerate content obsolescence as Apple's ecosystem moves forward. - 🔴 User sentiment is frustrated by the steep learning curve, which, combined with the lack of updates, creates a high churn risk for new learners. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2.67/5 | | Total Reviews | 3 | | Sentiment | Excited (70/100) | | Confidence | Medium | | Pricing Model | Paid | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Tutorial for OC** (this app) | 2.67/5 | Excited | 强 马 | | [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:** 强 马 - **Website:** [https://itunes.apple.com/us/app/id968261919?mt=8](https://itunes.apple.com/us/app/id968261919?mt=8) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/tutorial-for-oc/id968261919?uo=4) - **Dev Site:** [Official Website](https://itunes.apple.com/us/app/id968261919?mt=8) - **Sources:** Developer website content, App store metadata, User reviews. ## 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.
