US Market. No publisher influence. > **Key Insight:** Data Structures Basics is a education app by AFTW LLC. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Education | | **Developer** | AFTW LLC | | **Pricing** | Free | | **Platforms** | iOS | | **Confidence** | Low (0.2/1.0) | | **Data Age** | 6d | ## Metadata & Market Performance - **Publisher:** AFTW LLC - **Category:** Education - **Target Audience:** Computer science students and job seekers preparing for technical interviews, exams, or project work. - **Platforms:** iOS - **Version Reviewed:** 1.0 - **Report Date:** 2026-09-24 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.2/1.0) - **App Store ID (iOS):** 6771263396 - **Bundle ID:** com.quizfactory.global.datastructuresbasics - **Data Window:** Analysis based on signals collected up to 2026-09-24 ## Executive Snapshot **What it is:** Data Structures Basics is an education app for computer science students, providing 160 practice questions on core data structures and algorithms on iOS. **Why users hire it:** Students use the app to bypass account-creation friction and study offline during transit or in limited-connectivity environments. ## App DNA (Features & Intent) - **[Differentiator] FSRS Spaced-Repetition:** Uses FSRS algorithms to optimize review intervals for 160 computer science questions. - **[Differentiator] No Login Required:** Allows immediate access to all study materials without account creation. * *User Intent:* Users are motivated by consistent progression and daily incentives. - **[Standard] Offline Practice:** Enables full access to question banks without an active internet connection. * *User Intent:* Users want uninterrupted access without internet dependency. ## Market Position {#market-position} Data Structures Basics functions as a niche education utility with no active chart presence. The lack of recent updates (126 days since last store update) signals a maintenance-only posture. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all 160 questions and features - **Analysis:** The app is currently offered as a free, standalone tool with no visible monetization gates or subscription tiers. ## SWOT Analysis {#swot} **Core Strengths:** - No-login requirement maximizes install-to-first-question conversion - Offline-first architecture removes connectivity dependency for students **Growth Levers:** - Implementing premium tier for advanced mock exams could capture revenue ## App Momentum (Zombie) {#momentum} - Quiet 4 months, no major releases. - Last major release May 2026. > **Cadence:** 1 total versions · 0 majors in last 6 months · 126 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Data Structures Basics is an education app that is completely free. > **Bottom Line:** The no-login, offline-first design provides a clean entry for students, but the 4-month development silence risks obsolescence. Refreshing the question bank would stabilize the app's value as a reliable interview-prep utility. **Best for:** Computer science students and job seekers preparing for technical interviews, exams, or project work. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit question bank for technical accuracy because the 4-month silence risks obsolescence → maintain user trust ### Outlook: Mixed The education utility market is consolidating around platforms that offer community-driven content and frequent question-bank updates. Data Structures Basics remains in a maintenance-only state, which will likely lead to user churn as students migrate to more active, updated interview-prep resources. - 🔴 The 126-day update gap indicates a maintenance-only cadence, which risks losing relevance as technical interview questions evolve. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Data Structures Basics** (this app) | N/A/5 | N/A | AFTW LLC | | [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:** AFTW LLC - **Website:** [https://quizfactoryapp.github.io/](https://quizfactoryapp.github.io/) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/data-structures-basics/id6771263396?uo=4) - **Dev Site:** [Official Website](https://quizfactoryapp.github.io/) - **Sources:** Developer website content, App store metadata. ## 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 Basics free to use?
