With a 4.55/5 rating from 15.3K reviews, it shows mixed user reception. > **Bottom Line:** Bubble Level Plus+ provides a functional core utility, but the aggressive monetization strategy currently alienates the user base.

Bubble Level Plus+ remains in a maintenance-only state, which will likely lead to a gradual decline in relevance as users migrate to more reliable, ad-light alternatives. - 🔴 The lack of updates for nearly a year suggests the developer has deprioritized feature expansion, leaving the app vulnerable to modern competitors. - 🔴 Persistent complaints regarding monetization friction and sensor accuracy indicate that the core user experience is degrading, which will likely accelerate long-term churn. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.55/5 | | Total Reviews | 15.3K | | Sentiment | Mixed (45/100) | | Confidence | High | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Bubble Level Plus+** (this app) | 4.55/5 | Mixed | Tue Nguyen Minh | | [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 | | [App For Siri Commands Tips](https://marlvel.ai/apps/app-for-siri-commands-tips) | N/A/5 | N/A | Anh La Phan Son | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Bin Days - Bin Reminder](https://marlvel.ai/apps/bin-days-bin-reminder) | N/A/5 | N/A | Vicki Partridge | ## Company Profile - **Developer:** Tue Nguyen Minh - **Website:** [https://www.phoenixmobileonline.com](https://www.phoenixmobileonline.com) ## Data Sources & Links - **App Store ID:** 618064263 - **Dev Site:** [Official Website](https://www.phoenixmobileonline.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 - [*App For Siri Commands Tips*](https://marlvel.ai/apps/app-for-siri-commands-tips) (Anh La Phan Son) · N/A Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Bin Days - Bin Reminder*](https://marlvel.ai/apps/bin-days-bin-reminder) (Vicki Partridge) · N/A Rating - [*Controller Tester FGC*](https://marlvel.ai/apps/controller-tester-fgc) (Aaron Lowe) · 5.0/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Gear Ratio Calculator & RPM*](https://marlvel.ai/apps/cog-gear-ratio-calculator) (Linh Phan Nhat Khanh) · N/A Rating - [*MDflow Web Clipper*](https://marlvel.ai/apps/mdflow-web-clipper) (DataOps, s.r.o.) · N/A Rating - [*NordVPN: VPN Fast & Secure*](https://marlvel.ai/apps/com-nordvpn-nordvpn) (Nordvpn S.A.) · 4.7/5 Rating ## Frequently Asked Questions {#faq} ### Is Bubble Level Plus+ accurate for home improvement projects?

Bubble Level Plus+ is part of the iMetalBox suite and focuses on simple, audible feedback.
