US Market. No publisher influence. > **Key Insight:** Math Angle is a education app by Heiko Etzold. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Education | | **Developer** | Heiko Etzold | | **Pricing** | Free | | **Platforms** | iOS | | **Confidence** | Low (0.05/1.0) | | **Data Age** | 33d | ## Metadata & Market Performance - **Publisher:** Heiko Etzold - **Category:** Education - **Target Audience:** Students and educators looking for basic geometric practice tools for angle identification and estimation. - **Platforms:** iOS - **Version Reviewed:** 3.0.1 - **Report Date:** 2026-08-29 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.05/1.0) - **App Store ID (iOS):** 715739128 - **Bundle ID:** de.heiko-etzold.Winkel - **Performance Trend:** Stable - **Data Window:** Analysis based on signals collected up to 2026-08-29 ## Executive Snapshot **What it is:** Math Angle is a geometry education utility for iOS that allows students to estimate, identify, and draw specific angles. **Why users hire it:** The tool removes the need for physical protractors and paper-based angle worksheets, providing an immediate feedback loop for geometric practice. ## App DNA (Features & Intent) - **[Standard] Angle Type Selection:** Users choose specific categories of angles to practice within the educational interface. - **[Standard] Angle Estimation:** Interactive tool for users to estimate angle measurements, providing a feedback loop for geometric learning. * *User Intent:* Users seek enhanced value through premium features. - **[Standard] Drawing Tools:** Interface allows users to manually draw and identify special angles on the screen. ## Market Position {#market-position} Math Angle occupies a niche utility position in the Education category, remaining static since 2020. The absence of recent updates or a monetization model signals a developer focus on legacy utility rather than market share expansion. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** Math Angle is distributed as a free utility without visible monetization, subscriptions, or in-app purchases. ## SWOT Analysis {#swot} **Core Strengths:** - Focused geometric toolset for angle estimation and drawing provides a clear, single-purpose utility for classroom settings **Growth Levers:** - Visual refresh and the addition of progress tracking could differentiate Math Angle from generic math drill apps ## What's New - **Latest (v3.0.1, 6 years ago):** Addressed stability issues to prevent iPhone application crashes. ## App Momentum (Zombie) {#momentum} - Dormant since April 2020. - No feature updates in six years. > **Cadence:** 1 total versions · 0 majors in last 6 months · 2330 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Math Angle is an education app that is completely free. > **Bottom Line:** Math Angle serves as a legacy utility that no longer meets current educational standards, and sunsetting the app would allow the developer to focus resources on modern, adaptive learning tools. **Best for:** Students and educators looking for basic geometric practice tools for angle identification and estimation. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the application because the six-year development gap makes it a brand liability → reduce support overhead ### Outlook: Declining The educational utility market is consolidating around platforms that offer adaptive difficulty and progress tracking. Math Angle's static nature leaves it exposed to obsolescence, as it lacks the engagement loops necessary to retain users against modern, updated alternatives. - 🔴 The six-year development hiatus indicates the product is in terminal maintenance, which erodes user trust as hardware standards evolve. - 🔴 Lack of modern gamification features limits the ability to compete with current educational apps, leading to inevitable user attrition. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Math Angle** (this app) | N/A/5 | N/A | Heiko Etzold | | [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:** Heiko Etzold ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/math-angle/id715739128?uo=4) - **Sources:** App store metadata. ## 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 Math Angle still being updated?
