The lack of updates for over 660 days signals a maintenance-only posture that struggles to maintain visibility against active, ad-supported competitors. ## Monetization Strategy - **Model:** Paid - **Tiers:** One-time purchase at $1.99 - **Price:** iOS: $1.99 - **Analysis:** The app utilizes a flat-fee paid model at $1.99, targeting users who prefer a one-time cost over subscription-based utility tools. ## SWOT Analysis {#swot} **Core Strengths:** - 59-calculator library establishes category authority **Growth Levers:** - Localized pricing could capture price-sensitive student segments ## What's New - **Latest (v4.0, 1 years ago):** Version 4.0 introduces a major UI redesign, a new settings screen, a recent calculators section, and enhanced search functionality. ## App Momentum (Zombie) {#momentum} - Dormant release velocity for 22 months - No feature expansion since late 2024 > **Cadence:** 1 total versions · 1 majors in last 6 months · 663 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Engineering Calculator is an education app that is a paid app. It holds a 1/5 rating from 1 review. > **Bottom Line:** Engineering Calculator rests on its specialized library, but the 22-month update gap risks obsolescence in a category where accuracy is the primary retention lever. Maintaining technical parity is the only way to defend the $1.99 price point against free, ad-supported rivals. **Best for:** Engineering students and professionals requiring a portable, offline reference for standard civil, electrical, and mechanical calculations. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit library accuracy because the app has been dormant for 22 months → maintain user trust ### Outlook: Declining The engineering utility market is consolidating around tools that offer frequent formula updates and cloud-sync capabilities. Engineering Calculator's maintenance-only posture leaves it exposed to churn as students migrate to more active, ad-supported alternatives that provide a current, evolving feature set. - 🔴 The 663-day update gap indicates a maintenance-only posture, which prevents the app from addressing modern OS requirements or user-requested formula updates. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 1/5 | | Total Reviews | 1 | | Confidence | Low | | Pricing Model | Paid | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Engineering Calculator** (this app) | 1/5 | N/A | loay setrak | | [Catbus Student](https://marlvel.ai/apps/catbus-student) | 4.3/5 | N/A | Cohota Join Stock Company | | [Money Matrix (CAD)](https://marlvel.ai/apps/money-matrix-cad) | 5.0/5 | N/A | Blooming Kids Software LLC | | [Quran Treasure Island for Kids](https://marlvel.ai/apps/quran-treasure-island-for-kids) | 4.9/5 | Mixed | Akeela Manekia | | [Valencia College - MyVC](https://marlvel.ai/apps/valencia-college-myvc) | 5.0/5 | N/A | Valencia College | | [Verbi: Learn a New Language](https://marlvel.ai/apps/verbi-learn-a-new-language) | 4.3/5 | n/a | ACADIA LABS INC. | ## Company Profile - **Developer:** loay setrak - **Website:** [https://loaysetrak.com/#home](https://loaysetrak.com/#home) - **Social:** [X/Twitter](https://twitter.com/loay) ## Data Sources & Links - **App Store ID:** 1297957037 - **Dev Site:** [Official Website](https://loaysetrak.com/#home) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*Catbus Student*](https://marlvel.ai/apps/catbus-student) (Cohota Join Stock Company) · 4.3/5 Rating - [*Money Matrix (CAD)*](https://marlvel.ai/apps/money-matrix-cad) (Blooming Kids Software LLC) · 5.0/5 Rating - [*Quran Treasure Island for Kids*](https://marlvel.ai/apps/quran-treasure-island-for-kids) (Akeela Manekia) · 4.9/5 Rating - [*Valencia College - MyVC*](https://marlvel.ai/apps/valencia-college-myvc) (Valencia College) · 5.0/5 Rating - [*Verbi: Learn a New Language*](https://marlvel.ai/apps/verbi-learn-a-new-language) (ACADIA LABS INC.) · 4.3/5 Rating - [*자주 틀리는 우리말*](https://marlvel.ai/apps/app--424) (DaolSoft, Co., Ltd.) · N/A Rating - [*달공부 - 한 달 공부 다이어리 + 루틴/공부 타이머*](https://marlvel.ai/apps/azlabs-dalstudy) (SuWon Choi) · N/A Rating - [*타요콘 - 타요 아바타 놀이동화*](https://marlvel.ai/apps/com-kigle-project-tayocon) (KIGLE) · 3.1/5 Rating - [*천자문 워치*](https://marlvel.ai/apps/app--385) (kim juyoung) · N/A Rating - [*천자문 공부 도우미*](https://marlvel.ai/apps/app--382) (kim juyoung) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Engineering Calculator suitable for professional use?
