Prioritizing an offline-first experience would unlock higher retention among professional users. **Best for:** DIY enthusiasts, professionals needing precise measurement tools, and social media users looking to create custom stickers. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Enable offline mode for core measurement tools because mandatory connectivity is the top complaint → increase retention ### Outlook: Declining The utility app market is consolidating around native system tools, leaving Measure Angles - Bubble Level exposed to churn. Unless the developer shifts to an offline-first experience, the current ad-heavy strategy will continue to erode the user base, leading to further rating compression. - 🔴 Mandatory internet connectivity for local tools continues to drive negative reviews, signaling that the latest update failed to address core user friction. - 🔴 Heavy ad resource consumption causes interface freezes, which erodes the daily active habit and compounds the rating drag already visible on the platform. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.61/5 | | Total Reviews | 7.1K | | Sentiment | Mixed (45/100) | | Confidence | Medium | | Pricing Model | Subscription | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Measure Angles - Bubble Level** (this app) | 4.61/5 | Mixed | WHATSTICKER APPS SRL | | [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:** WHATSTICKER APPS SRL - **Website:** [https://www.whatsticker.app/](https://www.whatsticker.app/) - **Social:** [Facebook](https://www.facebook.com/profile.php?id=100063996944405) · [TikTok](https://www.tiktok.com/@whatsticker_app) ## Data Sources & Links - **App Store ID:** 458980311 - **Google Play ID:** com.hscnapps.bubblelevel - **Dev Site:** [Official Website](https://www.whatsticker.app/) - **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 - [*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 - [*도사폰 (만세력 역학도구)*](https://marlvel.ai/apps/app--656) (Softchaser Company Limited) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Does Measure Angles - Bubble Level work without an internet connection?
