The 11-year update gap prevents it from competing with modern, actively maintained engineering utilities. ## Monetization Strategy - **Model:** Free - **Tiers:** Completely free utility - **Analysis:** The app operates as a free educational utility with no IAP or subscription tiers, serving as a brand-building tool for Keysight Technologies. ## 🔴 User Sentiment (Low Confidence: 4 of 4 reviews analyzed) {#user-sentiment} - **Overall Rating:** 3.25/5 - **Platform Split:** iOS 3.3/5 (4 ratings) - **Overall Sentiment:** Frustrated ### Top Praises - **The core logic design provides a helpful and engaging experience for users interested in digital circuitry** ### Top Complaints (Impact Areas) - **Frequent application crashes during startup and usage prevent users from accessing the core logic design tools** ## SWOT Analysis {#swot} **Core Strengths:** - Realtime Logic Simulator establishes technical authority - Amplifier Circuit Designer automates complex Op-Amp parameters **Growth Levers:** - Modernizing the simulator engine would restore utility - Expanding component library addresses user-requested logic tools ## What's New - **Latest (v2.1, 11 years ago):** Addressed compatibility issues for iOS 8.1. ## App Momentum (Zombie) {#momentum} - No functional updates since 2014. - Dormant development for over 11 years. > **Cadence:** 1 total versions · 0 majors in last 6 months · 4316 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Electronics Handbook is an education app that is completely free. It holds a 3.25/5 rating from 4 reviews. > **Bottom Line:** Electronics Handbook remains a dormant asset that relies on legacy utility to maintain its presence, but the persistent instability prevents it from serving its purpose as a brand-building tool for Keysight Technologies. **Best for:** Electronic and electrical engineering students and professors requiring quick reference tools and circuit simulation. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit codebase for iOS compatibility because the app has not been updated since 2014 → restore basic functionality ### Outlook: Declining The market for educational engineering tools is shifting toward actively maintained, cross-platform simulators that offer cloud integration. Electronics Handbook is currently failing to meet basic stability expectations, which turns a potential brand-building asset into a source of negative sentiment for Keysight Technologies. - 🔴 The 11-year update gap indicates a lack of maintenance, which directly causes the persistent crashes reported by users. - 🔴 The lack of feature expansion despite user requests for multiplexers and demultiplexers signals that the app is in a terminal state. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.25/5 | | Total Reviews | 4 | | Sentiment | Frustrated (40/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Electronics Handbook** (this app) | 3.25/5 | Frustrated | Keysight Technologies, Inc. | | [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:** Keysight Technologies, Inc. ## Data Sources & Links - **App Store ID:** 723317441 - **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 - [*MapTap.gg*](https://marlvel.ai/apps/nibble-games-maptap) (MapTap Inc) · 4.9/5 Rating | Excellent Sentiment - [*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 ## Frequently Asked Questions {#faq} ### Is Electronics Handbook still supported by Keysight Technologies?
