With a 3/5 rating from 8 reviews, it faces significant user friction. > **Bottom Line:** Stabilizing the core reading experience is the prerequisite for any feature expansion, as rendering failures directly undermine the app's primary utility. Addressing these technical gaps would unlock the retention potential of the existing devotional integration. **Best for:** Korean-speaking Christians seeking structured Bible study tools, theological reference materials, and daily devotional content. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Rebuild the note-persistence layer because note-loss is a top-reported frustration → improve retention. ### Feature Gaps vs Competitors - Dual-language scripture view (requested by users) ### Outlook: Mixed The religious study category is increasingly shifting toward high-frequency, ad-supported, or subscription-based models that prioritize stability and cross-reference features. Duranno Bible & Dictionary remains exposed by its maintenance-only update cadence; without a shift toward resolving core rendering and data-persistence bugs, the app will continue to lose ground to more responsive, modern alternatives. - 🔴 Persistent content rendering failures after updates erode user trust, which compounds the rating drag already visible on the platform. - 🟢 The core scripture reading experience remains a convenient, easy-to-navigate tool for daily engagement, providing a stable foundation for future fixes. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3/5 | | Total Reviews | 8 | | Sentiment | Frustrated (35/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **두란노 성경&사전** (this app) | 3/5 | Frustrated | Duranno | | [리디 - 웹툰, 만화, 웹소설, 전자책 모두 여기에!](https://marlvel.ai/apps/com-initialcoms-bom) | 4.4/5 | N/A | RIDI Corporation | | [리드모어 - 독서 기록을 깔끔하게](https://marlvel.ai/apps/com-jieun-readmore) | N/A/5 | N/A | Jieun Baek | | [밀리의서재](https://marlvel.ai/apps/kr-co-millie-millieshelf) | 4.3/5 | N/A | kt millie seojae Co.,Ltd | | [대한성서공회 모바일성경](https://marlvel.ai/apps/kr-or-bskorea-bible) | 1.8/5 | N/A | Korean Bible Society | | [100 Things: Diggers](https://marlvel.ai/apps/dk-whyse-diggers) | 3.0/5 | N/A | 100 Things App LLC | ## Company Profile - **Developer:** Duranno - **Website:** [https://www.duranno.com](https://www.duranno.com) - **Social:** [Instagram](https://www.instagram.com/duranno_) · [Facebook](https://www.facebook.com/durannobooks) · [YouTube](https://www.youtube.com/durannobooks) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/%EB%91%90%EB%9E%80%EB%85%B8-%EC%84%B1%EA%B2%BD-%EC%82%AC%EC%A0%84/id418750972?uo=2) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.duranno.brand&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.duranno.com) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*리디 - 웹툰, 만화, 웹소설, 전자책 모두 여기에!*](https://marlvel.ai/apps/com-initialcoms-bom) (RIDI Corporation) · 4.4/5 Rating - [*리드모어 - 독서 기록을 깔끔하게*](https://marlvel.ai/apps/com-jieun-readmore) (Jieun Baek) · N/A Rating - [*밀리의서재*](https://marlvel.ai/apps/kr-co-millie-millieshelf) (kt millie seojae Co.,Ltd) · 4.3/5 Rating - [*대한성서공회 모바일성경*](https://marlvel.ai/apps/kr-or-bskorea-bible) (Korean Bible Society) · 1.8/5 Rating - [*100 Things: Diggers*](https://marlvel.ai/apps/dk-whyse-diggers) (100 Things App LLC) · 3.0/5 Rating - [*1611 King James Bible PRO*](https://marlvel.ai/apps/com-mybible-pro) (Haven Tran) · 3.8/5 Rating - [*200+ Islamic Stories (Pro)*](https://marlvel.ai/apps/com-islamicstories) (ImranQureshi.com) · 3.7/5 Rating - [*40: Discipleship*](https://marlvel.ai/apps/com-livingworthyministries-40discipleship) (Living Worthy Ministries, LLC) · N/A Rating - [*ボイス オブ デイジー 5*](https://marlvel.ai/apps/jp-co-cypac-vodi5) (CYPAC Co.,Inc.) · 2.5/5 Rating - [*5 Little Monkeys Collection #1*](https://marlvel.ai/apps/com-oceanhousemedia-book5lmcollection1) (Oceanhouse Media) · 4.4/5 Rating ## Frequently Asked Questions {#faq} ### Is Duranno Bible & Dictionary good for daily Bible study?
