The 32-day gap since the last update highlights a maintenance-mode cadence that fails to address persistent accuracy complaints. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free tier with full feature access, In-app purchases available - **Analysis:** The app utilizes a freemium model with in-app purchases, though specific premium tier pricing is not disclosed. ## 🔴 User Sentiment (Medium Confidence: 3 of 3 reviews analyzed) {#user-sentiment} - **Overall Rating:** 1.83/5 - **Platform Split:** iOS 1.8/5 (6 ratings) - **Overall Sentiment:** Upset ### Top Complaints (Impact Areas) - **Aggressive advertising displays within the interface prevent users from accessing core functionality without interruption** ## SWOT Analysis {#swot} **Core Strengths:** - 3-in-1 measurement modes provide broad utility across physical environments. - Smart Angle Preset enables professional-grade deviation alerts. **Growth Levers:** - Transition from ad-heavy monetization to transparent Pro-tier could recover user trust. - Refining gyroscope-based calibration could address primary accuracy complaints. ## What's New - **Latest (v27, 1 months ago):** Introduced a redesigned user interface optimized for Android 17. ## App Momentum (Maintenance) {#momentum} - Shipped Android 17 UI redesign. - Ships bug fixes at 7-week cadence. > **Cadence:** 2 total versions · 2 majors in last 6 months · 32 days since last update · 21 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Protractor - Measure Angles is an utilities app that is free with in-app purchases. It holds a 1.83/5 rating from 6 reviews. > **Bottom Line:** The current reliance on intrusive ads and software bundling invalidates the core utility, and the PM must pivot to prioritize measurement accuracy to prevent further brand erosion. Restoring basic reliability is the only path to recovering the 1.83-star rating. **Best for:** DIY enthusiasts, students, and professionals requiring quick, portable angle measurement tools. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Deprecate unwanted software bundling because it is a top-cited reason for negative reviews → restore user trust ### Outlook: Declining The outlook for Protractor - Measure Angles is declining as the current maintenance-mode cadence fails to address fundamental accuracy and monetization friction. Without a pivot toward reliable measurement and transparent business practices, the app will continue to lose ground to ad-free, high-accuracy alternatives in the Utilities space. - 🔴 Persistent complaints regarding measurement inaccuracy erode the tool's core value proposition, leading to negative real-world outcomes for students. - 🔴 Aggressive ad-bundling and unwanted software installations drive high churn and negative sentiment, which compounds the rating drag. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 1.83/5 | | Total Reviews | 6 | | Sentiment | Upset (10/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Protractor - Measure Angles** (this app) | 1.83/5 | Upset | Noadit, Inc. | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.5/5 | Mixed | Free VPN LLC | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.5/5 | Mixed | Fuxin Technology | ## Company Profile - **Developer:** Noadit, Inc. - **Website:** [https://www.noadit.com](https://www.noadit.com) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/protractor-measure-angles/id1601838509?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.exeysoft.protractor&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.noadit.com) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.9/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.5/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 Rating - [*VPN 365-Master WIFI Security*](https://marlvel.ai/apps/vpn-365-master-wifi-security) (vpn fast) · 4.6/5 Rating - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating - [*로또 황금번호 생성기*](https://marlvel.ai/apps/lotto-lottogold) (jaehwan lee) · N/A Rating ## Frequently Asked Questions {#faq} ### Is Protractor - Measure Angles accurate enough for school assignments?
