With a 4.75/5 rating from 696 reviews, it delivers strong user satisfaction. > **Bottom Line:** Automating the conversion of photos into patterns provides a clear entry point for beginners, but the restrictive generation cap and technical instability currently limit retention. Addressing download latency would stabilize the user experience and reduce the churn pressure driving negative sentiment. **Best for:** Crochet enthusiasts ranging from beginners to experienced crafters looking for digital pattern management and project generation tools. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit image-processing pipeline because crashes and slow downloads are top complaints → improve stability ### Outlook: Mixed The crochet-tool market is consolidating around apps that offer reliable, offline-capable pattern management. Yarniby remains exposed due to its maintenance-only release cadence and technical instability, which risks alienating the beginner segment that relies on its core generation tool. - 🔴 Technical instability during image uploads and slow download speeds erode the daily active habit, compounding the rating drag already visible in recent reviews. - ⚪ The latest release focused on language support rather than resolving core performance complaints, signaling a maintenance-heavy cadence rather than active feature expansion. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.75/5 | | Total Reviews | 696 | | Sentiment | Excited (65/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Yarniby: crochet and patterns** (this app) | 4.75/5 | Excited | Stefano De Filippo Roia | | [Alarmy - Loud alarm clock](https://marlvel.ai/apps/alarmy-loud-alarm-clock) | 4.8/5 | Excited | Delight Room Co., Ltd. | | [Journey - Diary, Journal](https://marlvel.ai/apps/com-journey-ios-app) | 4.6/5 | Excited | Two App Studio Pte.
