(Strategic Takeaway) {#so-what} Electricity Formulas is a market-leading education app that is free with in-app purchases. With a 4.57/5 rating from 181 reviews, it delivers strong user satisfaction. > **Bottom Line:** Electricity Formulas serves as a functional reference tool, but the lack of technical depth limits its utility for professionals. Expanding the database to include advanced derivations would unlock higher retention among the power-user segment currently finding the content sparse. **Best for:** Students and electrical professionals requiring a quick reference tool for standard electrical formulas. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Expand formula database depth because professional users report insufficient technical detail → increase long-term retention ### Feature Gaps vs Competitors - AI-driven step-by-step explanations (available in 数学公式集 but absent here) ### Outlook: Stable The educational reference market is shifting toward interactive, AI-assisted learning, which puts static formula libraries at a competitive disadvantage. Electricity Formulas must transition from a simple reference list to a more comprehensive technical resource to avoid being displaced by AI-driven competitors. - 🔴 The maintenance-only release cadence (no feature updates in 4 months) leaves the app vulnerable to AI-driven rivals that actively iterate on learning technology. - ⚪ User sentiment remains positive regarding the current library structure, but the lack of depth prevents the app from scaling to professional-grade engineering needs. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.57/5 | | Total Reviews | 181 | | Sentiment | Excited (75/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | Android | | Key Features | 2 analyzed | | Trend | Mixed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Electricity Formulas** (this app) | 4.57/5 | Excited | Webtoweb | | [The Big Sky Above Us](https://marlvel.ai/apps/the-big-sky-above-us) | 4.5/5 | Thrilled | Near Future Marketing Inc. | | [Kinfolk](https://marlvel.ai/apps/kinfolk) | 4.7/5 | N/A | Kinfolk Tech Foundation | | [College Interactive](https://marlvel.ai/apps/college-interactive) | 3.0/5 | Mixed | Xinteractive | | [AR Globe - David Rumsey Maps](https://marlvel.ai/apps/ar-globe-david-rumsey-maps) | 4.7/5 | N/A | David Rumsey | | [EM elektro MANAGEMENT](https://marlvel.ai/apps/em-elektro-management) | N/A/5 | N/A | AppSisto | ## Company Profile - **Developer:** Webtoweb - **Website:** [https://www.webtoweb.fr](https://www.webtoweb.fr) ## Data Sources & Links - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=formulas.electricity&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.webtoweb.fr) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*The Big Sky Above Us*](https://marlvel.ai/apps/the-big-sky-above-us) (Near Future Marketing Inc.) · 4.5/5 Rating | Excellent Sentiment - [*Kinfolk*](https://marlvel.ai/apps/kinfolk) (Kinfolk Tech Foundation) · 4.7/5 Rating - [*College Interactive*](https://marlvel.ai/apps/college-interactive) (Xinteractive) · 3.0/5 Rating - [*AR Globe - David Rumsey Maps*](https://marlvel.ai/apps/ar-globe-david-rumsey-maps) (David Rumsey) · 4.7/5 Rating - [*EM elektro MANAGEMENT*](https://marlvel.ai/apps/em-elektro-management) (AppSisto) · N/A Rating - [*数学公式集 - ＡＩ解法カメラによる解き方・解説付き*](https://marlvel.ai/apps/jp-co-studyswitch-glossarymathformula) (StudySwitch, Inc.) · N/A Rating - [*AlgoApp - Flashcards*](https://marlvel.ai/apps/algoapp-flashcards) (AlgoApp Inc) · 4.5/5 Rating - [*Catbus Student*](https://marlvel.ai/apps/catbus-student) (Cohota Join Stock Company) · 4.3/5 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 ## Frequently Asked Questions {#faq} ### Is Electricity Formulas suitable for professional electrical engineers? While the app provides a useful quick-reference library for standard formulas, some professional users report that it lacks the technical depth required for advanced engineering tasks. ### How does Electricity Formulas compare to AI-based math apps? Unlike AI-driven apps that provide step-by-step solutions and explanations for complex problems, Electricity Formulas acts as a static, categorized reference guide for standard formulas. ### Does Electricity Formulas contain intrusive advertisements? The app operates on a freemium model where access to the educational content is supported by advertisements. ### What are some alternatives for electrical engineering students? Students looking for more interactive learning may consider apps that offer AI-driven problem solving or step-by-step explanations for complex formulas. ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
