**[Geometry Calculator PRO-YOKIE](https://marlvel.ai/apps/geometry-calculator-pro-yokie)** by nakhon phagdeechat: This is a direct feature-set competitor that has recently entered the market with a focus on offline utility. - Includes a history and export feature that allows students to save and share their calculations - **[CalcFinals](https://marlvel.ai/apps/glass-rusty-calcfinals-calcfinals)** by Russel Glass: A new entrant that targets the academic productivity space, potentially diverting student attention from specialized calculators. - Focuses on grade management and scenario analysis, shifting the value from calculation to academic planning ## What's New - **Latest (v2.2.0, 4 months ago):** General app performance optimization. ## App Momentum (Zombie) {#momentum} - Quiet 4 months, bug fixes only. - Last major release January 2026. > **Cadence:** 1 total versions · 0 majors in last 6 months · 134 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Pythagorean theorem calculator is a market-leading education app that is free with in-app purchases. With a 4.53/5 rating from 1.2K reviews, it delivers strong user satisfaction. > **Bottom Line:** Transitioning to a hybrid monetization model would address the ad-disruption complaints that currently threaten the app's utility-first retention loop. **Best for:** Students and scientists requiring a quick, dedicated tool for Euclidean geometry calculations. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Introduce a low-cost ad-free tier because user complaints flag ads as the top workflow disruptor → stabilize retention ### Feature Gaps vs Competitors - Step-by-step pedagogical explanations (available in Fraction Simplifier but absent here) ### Outlook: Declining The market for specialized math tools is shifting toward all-in-one utilities that offer graphing and step-by-step explanations. Pythagorean theorem calculator remains exposed: the recent shift to intrusive ad-monetization without a clear path to ad-free usage will erode the user base before a live-ops rival can capture the segment. - 🔴 Mandatory full-page advertisements in the latest release disrupt math workflows, causing users to cite the ad-heavy experience as a reason to uninstall. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.53/5 | | Total Reviews | 1.2K | | Sentiment | Excited (65/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | Android | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Pythagorean theorem calculator** (this app) | 4.53/5 | Excited | Webtoweb | | [Convertidor Números Romanos](https://marlvel.ai/apps/com-heartom-numerosromanos) | 4.5/5 | N/A | Hear_Tom | | [CalcFinals](https://marlvel.ai/apps/glass-rusty-calcfinals-calcfinals) | 5.0/5 | N/A | Russel Glass | | [Grade 10 Mathematical Literacy](https://marlvel.ai/apps/com-jsdtsolutions-grade12mathematicalliteracymobileapplication) | 4.5/5 | N/A | JSDT SOLUTIONS | | [PowerMath: K-12 Math Learning](https://marlvel.ai/apps/powermath-k-12-math-learning) | 3.9/5 | N/A | nguyen thanh | | [Geometry Calculator lite](https://marlvel.ai/apps/geometry-calculator-lite) | 4.5/5 | N/A | V PUGAZHENTHI | ## 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=com.calculator.pythagoras&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.webtoweb.fr) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Convertidor Números Romanos*](https://marlvel.ai/apps/com-heartom-numerosromanos) (Hear_Tom) · 4.5/5 Rating - [*CalcFinals*](https://marlvel.ai/apps/glass-rusty-calcfinals-calcfinals) (Russel Glass) · 5.0/5 Rating - [*Grade 10 Mathematical Literacy*](https://marlvel.ai/apps/com-jsdtsolutions-grade12mathematicalliteracymobileapplication) (JSDT SOLUTIONS) · 4.5/5 Rating - [*PowerMath: K-12 Math Learning*](https://marlvel.ai/apps/powermath-k-12-math-learning) (nguyen thanh) · 3.9/5 Rating - [*Geometry Calculator lite*](https://marlvel.ai/apps/geometry-calculator-lite) (V PUGAZHENTHI) · 4.5/5 Rating - [*Volume Calculator 3D*](https://marlvel.ai/apps/volume-calculator-3d) (V PUGAZHENTHI) · 4.9/5 Rating - [*Geometry Calculator.*](https://marlvel.ai/apps/geometry-calculator) (V PUGAZHENTHI) · 4.6/5 Rating - [*Abacus Mental Math Training*](https://marlvel.ai/apps/abacus-mental-math-training) (Peikun Duan) · 4.2/5 Rating - [*Geometry Calculator PRO-YOKIE*](https://marlvel.ai/apps/geometry-calculator-pro-yokie) (nakhon phagdeechat) · N/A Rating - [*Ncalc - Graphing Calculator 84*](https://marlvel.ai/apps/ncalc-graphing-calculator-84) (Tran Duy) · 4.6/5 Rating | Positive Sentiment ## Frequently Asked Questions {#faq} ### Is Pythagorean theorem calculator suitable for high school geometry?
