Shipped minor bug fixes in latest release. - Climbed to #33 US Photography chart. > **Cadence:** 5 total versions · 1 majors in last 6 months · 65 days since last update · 560 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Decalcomanie Gallery is a games app that is completely free. With a 4.65/5 rating from 4.3K reviews, it draws more critical themes in recent reviews than its store average suggests. > **Bottom Line:** Decalcomanie Gallery attracts casual users through its relaxing, simple interface, but the latest navigation regression creates a high-friction churn risk, so the team must prioritize restoring standard back-button behavior to stabilize the user base. **Best for:** Casual gamers seeking low-stress, creative, and relaxing mobile entertainment. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Restore standard back-navigation logic because the current gesture forces app closure, causing high churn → recover daily active habit. ### Feature Gaps vs Competitors - Social video sharing (available in Artbook but absent here) ### Outlook: Declining Casual creative traffic is consolidating around apps with higher update cadences and deeper feature sets. Decalcomanie Gallery's maintenance-mode posture leaves it exposed to rivals that offer social sharing and advanced tools, so revenue growth hinges on fixing the navigation regression to prevent immediate churn. - 🔴 Navigation regressions in the latest update force app closure, which erodes the daily active habit and compounds the rating drag. - 🔴 The lack of advanced editing tools restricts the app to basic adjustments, limiting its appeal against feature-rich competitors like Color Aura. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.65/5 | | Total Reviews | 4.3K | | Sentiment | Frustrated (35/100) | | Confidence | High | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Decalcomanie Gallery** (this app) | 4.65/5 | Frustrated | MondayOFF | | [Dark Color: Paint by Number](https://marlvel.ai/apps/com-paint-color-lite) | 4.5/5 | n/a | POMELO TECH | | [K-POP idols Coloring by Number](https://marlvel.ai/apps/com-peakadventurecoloringbook-bhr) | N/A/5 | N/A | YOUSSEF BOUHROUR | | [Princess Coloring Book Kids](https://marlvel.ai/apps/com-abovegames-coloringglittergradientprincess) | 4.3/5 | N/A | Abovegames LTD | | [Fairytale Color by number game](https://marlvel.ai/apps/com-fairy-tale-happy-paint-by-number-coloring-game) | 4.8/5 | N/A | LoveColoring Game | | [Tomodachi studio life maker](https://marlvel.ai/apps/com-editorstudio-mycolor) | 2.1/5 | N/A | Emily Loughty | ## Company Profile - **Developer:** MondayOFF - **Website:** [https://www.mondayoff.me](https://www.mondayoff.me) - **Social:** [Instagram](https://www.instagram.com/mondayoff_official) · [Facebook](https://www.facebook.com/MondayOffGame) · [YouTube](https://www.youtube.com/channel/UCgYNSY4mEvtTjGUG7L56k6w) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/decalcomanie-gallery/id1494923122?uo=4) - **Dev Site:** [Official Website](https://www.mondayoff.me) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## Related Intel Reports - [*Dark Color: Paint by Number*](https://marlvel.ai/apps/com-paint-color-lite) (POMELO TECH) · 4.5/5 Rating - [*K-POP idols Coloring by Number*](https://marlvel.ai/apps/com-peakadventurecoloringbook-bhr) (YOUSSEF BOUHROUR) · N/A Rating - [*Princess Coloring Book Kids*](https://marlvel.ai/apps/com-abovegames-coloringglittergradientprincess) (Abovegames LTD) · 4.3/5 Rating - [*Fairytale Color by number game*](https://marlvel.ai/apps/com-fairy-tale-happy-paint-by-number-coloring-game) (LoveColoring Game) · 4.8/5 Rating - [*Tomodachi studio life maker*](https://marlvel.ai/apps/com-editorstudio-mycolor) (Emily Loughty) · 2.1/5 Rating - [*Color Aura: Paint by Number*](https://marlvel.ai/apps/color-aura-paint-by-number) (Oakever Games) · 4.8/5 Rating | Positive Sentiment - [*Silhouette Art Master Craft*](https://marlvel.ai/apps/silhouette-art-master-craft) (Aysha Sehar) · 4.2/5 Rating | Positive Sentiment - [*Mandala Coloring Pages Game*](https://marlvel.ai/apps/mandala-coloring-pages-game) (2 Monkeys) · 4.6/5 Rating | Positive Sentiment - [*Artbook - Paint by Number*](https://marlvel.ai/apps/artbook-paint-by-number) (Hyperfun) · 4.7/5 Rating - [*My Coloring Pages Book Game*](https://marlvel.ai/apps/my-coloring-pages-book-game) (BWEB SARL) · 4.3/5 Rating ## 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.
