(Strategic Takeaway) {#so-what} Data Structures is an education app that is completely free. It holds a 3.14/5 rating from 7 reviews. > **Bottom Line:** The offline-first architecture provides a clear utility, but the six-year development freeze has rendered the interface and code presentation obsolete. Addressing these technical regressions would unlock the value of the core curriculum for a modern student base. **Best for:** Computer science students and individuals seeking foundational knowledge in data structures and algorithms. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Audit code formatting and UI layout because users report poor readability and bloat → improve satisfaction ### Outlook: Declining The educational utility market is shifting toward interactive, frequently updated platforms that integrate with modern IDEs. Data Structures remains in maintenance mode, and without a technical refresh, it will continue to lose relevance to active competitors. - 🔴 The six-year development freeze (no updates since 2019) prevents the app from addressing modern UI standards, which erodes user trust and retention. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.14/5 | | Total Reviews | 7 | | Sentiment | Frustrated (25/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Data Structures** (this app) | 3.14/5 | Frustrated | Pawanpreet Singh | | [ALPA: Lernspiele für Kinder](https://marlvel.ai/apps/alpa-lernspiele-fur-kinder) | N/A/5 | N/A | ALPA Kids OU | | [ATPdigital (Legacy)](https://marlvel.ai/apps/atpdigital-legacy) | 2.0/5 | n/a | Bristol Groundschool International Ltd | | [Catbus Student](https://marlvel.ai/apps/catbus-student) | 4.3/5 | N/A | Cohota Join Stock Company | | [Chinese Tibetan Dictionary](https://marlvel.ai/apps/chinese-tibetan-dictionary) | 5.0/5 | Thrilled | Lobsang Monlam16922404891 | | [Legasthenie & LRS Trainer](https://marlvel.ai/apps/legasthenie-lrs-trainer) | N/A/5 | N/A | Matthias Aigner | ## Company Profile - **Developer:** Pawanpreet Singh ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/data-structures/id993677535?uo=4) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*ALPA: Lernspiele für Kinder*](https://marlvel.ai/apps/alpa-lernspiele-fur-kinder) (ALPA Kids OU) · N/A Rating - [*ATPdigital (Legacy)*](https://marlvel.ai/apps/atpdigital-legacy) (Bristol Groundschool International Ltd) · 2.0/5 Rating - [*Catbus Student*](https://marlvel.ai/apps/catbus-student) (Cohota Join Stock Company) · 4.3/5 Rating - [*Chinese Tibetan Dictionary*](https://marlvel.ai/apps/chinese-tibetan-dictionary) (Lobsang Monlam16922404891) · 5.0/5 Rating | Excellent Sentiment - [*Legasthenie & LRS Trainer*](https://marlvel.ai/apps/legasthenie-lrs-trainer) (Matthias Aigner) · N/A Rating - [*Lyceum Leaf Parent*](https://marlvel.ai/apps/lyceum-leaf-parent) (Techcess Business Solutions (Pvt) Ltd) · N/A Rating - [*Money Matrix (CAD)*](https://marlvel.ai/apps/money-matrix-cad) (Blooming Kids Software LLC) · 5.0/5 Rating - [*myTibetan*](https://marlvel.ai/apps/mytibetan) (Yury Nevalenny) · 4.8/5 Rating | Excellent Sentiment - [*Quran Treasure Island for Kids*](https://marlvel.ai/apps/quran-treasure-island-for-kids) (Akeela Manekia) · 4.9/5 Rating - [*Sudoku - Number Puzzle Pro*](https://marlvel.ai/apps/sudoku-number-puzzle-pro) (阳理 江) · N/A Rating ## Frequently Asked Questions {#faq} ### Is Data Structures suitable for beginners?
