(Strategic Takeaway) {#so-what} Vocabulary & Dictionary Lekses is a market-leading education app that is completely free. With a 4.72/5 rating from 578 reviews, it delivers strong user satisfaction. > **Bottom Line:** Lekses provides a high-utility, ad-free dictionary experience that retains users through its spaced-repetition study loop. The lack of development activity is the primary risk: a single update from a rival with cross-platform sync would likely erode the current user base. **Best for:** Students preparing for standardized tests like the SAT or GRE and writers seeking a distraction-free dictionary tool. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship custom word-saving lists because it is the top-requested feature → increase time-in-app ### Outlook: Stable The Education category is consolidating around apps that offer cross-platform sync and custom study paths. Lekses remains stable due to its ad-free utility, but the lack of development activity suggests it will lose ground to rivals that actively address user requests for personalization. - 🔴 The 14-month development silence signals a move to maintenance mode, which leaves the app vulnerable to rivals with more frequent update cadences. - 🟢 High sentiment scores (4.7 stars) indicate the core dictionary utility remains highly valued by writers, providing a stable base for potential future growth. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.72/5 | | Total Reviews | 578 | | Sentiment | Thrilled (85/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Vocabulary & Dictionary Lekses** (this app) | 4.72/5 | Thrilled | Lekses 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) | 4.1/5 | N/A | Cohota Join Stock Company | | [Chinese Tibetan Dictionary](https://marlvel.ai/apps/chinese-tibetan-dictionary) | 5.0/5 | Thrilled | Lobsang Monlam16922404891 | | [Insights to Behavior](https://marlvel.ai/apps/insights-to-behavior) | N/A/5 | N/A | Insights to Behavior | ## Company Profile - **Developer:** Lekses LLC ## Data Sources & Links - **App Store ID:** 1601203575 - **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) · 4.1/5 Rating - [*Chinese Tibetan Dictionary*](https://marlvel.ai/apps/chinese-tibetan-dictionary) (Lobsang Monlam16922404891) · 5.0/5 Rating | Excellent Sentiment - [*Insights to Behavior*](https://marlvel.ai/apps/insights-to-behavior) (Insights to Behavior) · N/A Rating - [*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 ## Frequently Asked Questions {#faq} ### Is Vocabulary & Dictionary Lekses free to use?
