The absence of recent feature investment leaves the app vulnerable to rivals that offer modern UI and cloud-sync capabilities. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all calculators and tools - **Analysis:** The app operates as a free utility with no visible subscription or IAP gates, relying on broad feature availability to maintain its user base. ## 🔴 User Sentiment (Low Confidence: 2 of 2 reviews analyzed) {#user-sentiment} - **Overall Rating:** 4.42/5 - **Platform Split:** iOS 4.4/5 (64 ratings) - **Overall Sentiment:** Frustrated - **Note:** The 4.42/5 store rating reflects cumulative history, while the Frustrated sentiment reflects recent user reviews analyzed by our AI pipeline. ### Top Praises - **The application provides a useful utility for users who need a basic calculator on their mobile device** ### Top Complaints (Impact Areas) - **The keyboard layout overlaps with calculation buttons, making it impossible to perform basic math operations** ## SWOT Analysis {#swot} **Core Strengths:** - Specialized academic toolset (Logic Gate Simulator) drives session frequency - All-in-one utility design reduces manual lookup time **Growth Levers:** - Localized UI/UX could capture non-English speaking engineering student segments ## What's New - **Latest (v2.6.11, 6 years ago):** General bug fixes and stability improvements. ## App Momentum (Zombie) {#momentum} - Dormant development for 75+ months - No feature updates since 2020 > **Cadence:** 1 total versions · 0 majors in last 6 months · 2297 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Electronics Circuit Calculator is an education app that is completely free. It holds a 4.42/5 rating from 64 reviews. > **Bottom Line:** The keyboard-UI overlap invalidates the app's core utility, and the six-year development freeze suggests the product is no longer a priority for the publisher. Addressing this regression would restore basic functionality, but the lack of modern features limits long-term viability. **Best for:** Computer engineering students, hobbyists, and career professionals requiring quick access to circuit calculations. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Audit keyboard-UI layout because overlap prevents basic math input → restore core utility ### Outlook: Declining The engineering utility market is consolidating around tools that offer cloud-sync and responsive UI, leaving Electronics Circuit Calculator exposed due to its stagnant development cadence. The current trajectory points to continued user erosion as the app fails to resolve basic interface regressions. - 🔴 The six-year development freeze prevents the app from adapting to modern screen sizes, causing UI regressions that break core math input. - 🔴 Persistent keyboard-overlap bugs prevent basic task completion, which will accelerate user churn toward actively maintained engineering calculators. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.42/5 | | Total Reviews | 64 | | Sentiment | Frustrated (35/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Electronics Circuit Calculator** (this app) | 4.42/5 | Frustrated | Mustafa Mohammed | | [AlgoApp - Flashcards](https://marlvel.ai/apps/algoapp-flashcards) | 4.5/5 | n/a | AlgoApp Inc | | [Elevate - Brain Training Games](https://marlvel.ai/apps/elevate-brain-training-games) | 4.7/5 | n/a | The Mind Company | | [Flashcards Deluxe](https://marlvel.ai/apps/flashcards-deluxe) | 4.5/5 | N/A | OrangeOrApple.com | | [Flash Cards Flashcards Maker](https://marlvel.ai/apps/flash-cards-flashcards-maker) | 4.0/5 | Mixed | Infinite Wave Media, LLC | | [Flashcards maker - AI generate](https://marlvel.ai/apps/flashcards-maker-ai-generate) | 4.1/5 | Mixed | Teleprompter LLC | ## Company Profile - **Developer:** Mustafa Mohammed ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/electronics-circuit-calculator/id967586965?uo=4) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*AlgoApp - Flashcards*](https://marlvel.ai/apps/algoapp-flashcards) (AlgoApp Inc) · 4.5/5 Rating - [*Elevate - Brain Training Games*](https://marlvel.ai/apps/elevate-brain-training-games) (The Mind Company) · 4.7/5 Rating - [*Flashcards Deluxe*](https://marlvel.ai/apps/flashcards-deluxe) (OrangeOrApple.com) · 4.5/5 Rating - [*Flash Cards Flashcards Maker*](https://marlvel.ai/apps/flash-cards-flashcards-maker) (Infinite Wave Media, LLC) · 4.0/5 Rating - [*Flashcards maker - AI generate*](https://marlvel.ai/apps/flashcards-maker-ai-generate) (Teleprompter LLC) · 4.1/5 Rating - [*Impulse - Brain Training*](https://marlvel.ai/apps/impulse-brain-training) (GMRD Apps Limited) · 4.6/5 Rating - [*Peak - Brain Training*](https://marlvel.ai/apps/peak-brain-training) (Synaptic Labs) · 4.7/5 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 ## Frequently Asked Questions {#faq} ### Is Electronics Circuit Calculator suitable for professional engineering work?
