With a 4.17/5 rating from 426 reviews, it delivers strong user satisfaction. > **Bottom Line:** Implementing a one-time purchase to remove ads would address the primary source of negative sentiment, unlocking higher user satisfaction without sacrificing the app's lightweight, privacy-focused utility. **Best for:** Users verifying display quality on new or used devices and individuals performing hardware diagnostics. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Ship a one-time purchase option to remove ads because user reviews explicitly request an ad-free experience → reduce negative sentiment ### Outlook: Stable The display diagnostic market is consolidating around tools that offer deeper hardware insights, and ScreenTest's recent expansion into burn-in and color accuracy tests keeps it relevant. However, the lack of a paid ad-free tier leaves the app vulnerable to competitors who offer cleaner, subscription-based experiences. - 🟢 The latest update introduced granular diagnostic tools that provide deeper insights into display health, increasing the app's utility for power users. - 🔴 Aggressive advertising patterns disrupt the user experience during diagnostic tasks, which compounds the frustration already visible in the review sentiment. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.17/5 | | Total Reviews | 426 | | Sentiment | Excited (75/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **ScreenTest - Dead Pixel Check** (this app) | 4.17/5 | Excited | Son Nguyen | | [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:** Son Nguyen - **Website:** [https://uax.io/](https://uax.io/) ## Data Sources & Links - **App Store ID:** 6760121949 - **Google Play ID:** io.uax.screentest - **Dev Site:** [Official Website](https://uax.io/) - **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 ScreenTest safe to use for checking my phone's display?
