Unless the app addresses its technical instability and search friction, it will likely see a gradual decline in new-user conversion as birders migrate to more interactive, social-first identification tools. - 🔴 Comparison tool crashes during field use erode user trust, which compounds the churn risk among power users who rely on the feature. - 🟢 High-quality content remains a strong retention hook, ensuring the app stays relevant for serious birders despite the lack of modern UI polish. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.84/5 | | Total Reviews | 2.9K | | Sentiment | Mixed (65/100) | | Confidence | High | | Pricing Model | Paid | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Sibley Birds 2nd Edition** (this app) | 4.84/5 | Mixed | mydigitalearth.com | | [Sky Tonight - Stargazing Guide](https://marlvel.ai/intel-report/reference/com-vitotechnology-sky-tonight-map-star-walk) | 4.8/5 | Excited | Vito Technology Inc. | | [Star Walk 2 Pro: Sky Map Live](https://marlvel.ai/intel-report/education/com-vitotechnology-starwalk2) | 4.7/5 | Mixed | Vito Technology Inc. | | [Cosmic-Watch](https://marlvel.ai/intel-report/education/cosmic-watch) | 4.9/5 | Thrilled | Celestial Dynamics AG | | [VolcanoMap](https://marlvel.ai/intel-report/education/volcanomap) | N/A/5 | N/A | Arctic Surf Designs | | [iKnow Dogs: Identify Breeds](https://marlvel.ai/intel-report/education/iknow-dogs-identify-breeds) | 4.7/5 | N/A | NATURE MOBILE | ## Company Profile - **Developer:** mydigitalearth.com - **Website:** [https://www.mydigitalearth.com](https://www.mydigitalearth.com) - **Social:** [Instagram](https://www.instagram.com/mydigitalearth) · [Facebook](https://www.facebook.com/mydigitalearthcom-140741589348477) · [X/Twitter](https://twitter.com/mydigitalearth) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/sibley-birds-2nd-edition/id1236011411?uo=2) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.mydigitalearth.sibleybirds) - **Dev Site:** [Official Website](https://www.mydigitalearth.com) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Sky Tonight - Stargazing Guide*](https://marlvel.ai/intel-report/reference/com-vitotechnology-sky-tonight-map-star-walk) (Vito Technology Inc.) — 4.8/5 Rating | Positive Sentiment - [*Star Walk 2 Pro: Sky Map Live*](https://marlvel.ai/intel-report/education/com-vitotechnology-starwalk2) (Vito Technology Inc.) — 4.7/5 Rating | Mixed Sentiment - [*Cosmic-Watch*](https://marlvel.ai/intel-report/education/cosmic-watch) (Celestial Dynamics AG) — 4.9/5 Rating | Excellent Sentiment - [*VolcanoMap*](https://marlvel.ai/intel-report/education/volcanomap) (Arctic Surf Designs) — N/A Rating | N/A Sentiment - [*iKnow Dogs: Identify Breeds*](https://marlvel.ai/intel-report/education/iknow-dogs-identify-breeds) (NATURE MOBILE) — 4.7/5 Rating | N/A Sentiment - [*Bird Feather Identification*](https://marlvel.ai/intel-report/reference/bird-feather-identification-1) (Bart Jacobs) — 3.5/5 Rating | N/A Sentiment - [*Hallow: Prayer & Meditation*](https://marlvel.ai/intel-report/reference/hallow-prayer-meditation) (Hallow, Inc.) — 4.7/5 Rating | Positive Sentiment - [*Islamic World - Ramadan 2026*](https://marlvel.ai/intel-report/reference/islamic-world-ramadan-2026) (AppAspect Technologies Pvt.
