(Strategic Takeaway) {#so-what} Diamond Art – Colors by Number is an established entertainment app that is available. With a 4.23/5 rating from 18.3K reviews, it shows polarized user reception. > **Bottom Line:** The app holds its niche through unique diamond-art textures but bleeds users to more stable, high-cadence competitors, so the PM must prioritize technical stability and cloud-save to defend the existing user base. **Best for:** Casual mobile users and families seeking stress-relief activities and simple, repetitive creative tasks. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] [HIGH IMPACT] Ship cloud-save because it is the top-requested feature → unlock data-loss frustration. — *Cloud save is the #1 requested feature in user sentiment analysis.* _(trade-off: deprioritize Push the wearable companion app sprint to Q3.)_ - [ ] [PIVOT] [MEDIUM IMPACT] Pivot weekly subscription to a 7-day trial model because reviews flag trial length as a conversion barrier → reduce refund surge. — *1★ reviews frequently cite trial length and paywall aggression as primary churn drivers.* _(trade-off: deprioritize Pause the price-test on the annual tier.)_ - [ ] [MAINTAIN] [HIGH IMPACT] Audit Android stability because technical crashes are the #2 complaint theme → stabilize the rating baseline. — *Android rating is 0.6 stars lower than iOS, driven by crash reports.* _(trade-off: deprioritize Same-quarter capacity available.)_ ### Feature Gaps vs Competitors - Cloud-based progress sync (available in Color by Number: Coloring Games) - Advanced precision-zoom tools (available in Pixel Art) - Generative AI content generation (available in Color Pop AI) ### Outlook: Mixed The casual coloring market is consolidating around high-velocity competitors that leverage AI and 3D mechanics to keep content fresh. Without addressing the technical debt on Android and implementing basic account-based syncing, the app will continue to lose its casual base to rivals with better stability and more frequent feature updates. - 🔴 Technical instability and progress loss on Android drive a persistent rating gap, which compounds churn pressure as users switch to more stable alternatives. - 🟢 The artist submission program reduces asset production costs, allowing for a sustainable content library that supports the core daily-update retention loop. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.23/5 | | Total Reviews | 18.3K | | Sentiment | Mixed (65/100) | | Confidence | High | | Pricing Model | Subscription | | Platforms | iOS & Android | | Key Features | 5 analyzed | | Trend | Declining | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Diamond Art – Colors by Number** (this app) | 4.23/5 | Mixed | EYEWIND LIMITED | | [Paint by Number Coloring Game](https://marlvel.ai/intel-report/games/com-paint-bynumber) | 4.7/5 | N/A | Oakever Games | | [Color by Number：Coloring Games](https://marlvel.ai/intel-report/entertainment/com-fungames-colorbynumber) | 4.7/5 | Excited | Wildlife Studios | | [Coloring Match](https://marlvel.ai/intel-report/games/com-jacobvanhaag-colormatch) | 4.5/5 | Mixed | SUPERSONIC STUDIOS LTD | | [Color Pop AI - Coloring Book](https://marlvel.ai/intel-report/entertainment/com-mwm-procolor) | 4.8/5 | Frustrated | MWM | | [Art Puzzle - Jigsaw Games](https://marlvel.ai/intel-report/games/com-easybrain-art-puzzle) | 4.8/5 | Excited | Easybrain Ltd | ## Company Profile - **Developer:** EYEWIND LIMITED - **Website:** [https://incolor.cc/en/](https://incolor.cc/en/) - **Social:** [Instagram](https://www.instagram.com/incolor.app) · [Facebook](https://www.facebook.com/InColorapp) · [X/Twitter](https://twitter.com/IncolorAPP) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/diamond-art-colors-by-number/id1363417265?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.colors.by.number.no.diamond&hl=en&gl=us) - **Dev Site:** [Official Website](https://incolor.cc/en/) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Paint by Number Coloring Game*](https://marlvel.ai/intel-report/games/com-paint-bynumber) (Oakever Games) — 4.7/5 Rating | N/A Sentiment - [*Color by Number：Coloring Games*](https://marlvel.ai/intel-report/entertainment/com-fungames-colorbynumber) (Wildlife Studios) — 4.7/5 Rating | Positive Sentiment - [*Coloring Match*](https://marlvel.ai/intel-report/games/com-jacobvanhaag-colormatch) (SUPERSONIC STUDIOS LTD) — 4.5/5 Rating | Mixed Sentiment - [*Color Pop AI - Coloring Book*](https://marlvel.ai/intel-report/entertainment/com-mwm-procolor) (MWM) — 4.8/5 Rating | Negative Sentiment - [*Art Puzzle - Jigsaw Games*](https://marlvel.ai/intel-report/games/com-easybrain-art-puzzle) (Easybrain Ltd) — 4.8/5 Rating | Positive Sentiment - [*Happy Color by Numbers Game*](https://marlvel.ai/intel-report/games/happy-color-by-numbers-game) (X-Flow) — 4.9/5 Rating | Positive Sentiment - [*Diamond Painting ASMR Coloring*](https://marlvel.ai/intel-report/games/diamond-painting-asmr-coloring) (Crazy Labs) — 4.6/5 Rating | Mixed Sentiment - [*Pixel Art － Color by Number*](https://marlvel.ai/intel-report/games/com-europosit-pixelcoloring) (Easybrain Ltd) — 4.7/5 Rating | Mixed Sentiment - [*Zen Color - Color By Number*](https://marlvel.ai/intel-report/games/happy-paint-color-coloring-number) (Oakever Games) — 4.8/5 Rating | N/A Sentiment - [*BESTPLAY Play to earn & donate*](https://marlvel.ai/intel-report/entertainment/bestplay-play-to-earn-donate) (Bestplay) — 4.7/5 Rating | Terrible Sentiment ## 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.
