The core product remains in a 157-day maintenance cycle with no functional changes. **Overall trend**: Declining **Compared at**: 2026-08-22 ### High-impact changes - **[Shifted] Competitive threat identification** (positioning) ### Medium-impact changes - **[Added] Expanded threat landscape** (swot) - **[Added] Alternative discovery** (audience) ## What's New - **Latest (v1.0.6, 5 months ago):** Refined Luma Pro screen design and resolved iPad/large iPhone layout scaling issues. ## App Momentum (Maintenance) {#momentum} - Maintenance-mode, no updates in 157 days. - Last major release five months ago. > **Cadence:** 1 total versions · 0 majors in last 6 months · 157 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Luma Sleep – Night Screen is an utilities app that is free with in-app purchases. It holds a 4.04/5 rating from 28 reviews. > **Bottom Line:** Luma Sleep provides a functional red light filter, but its maintenance-mode status and intrusive UX patterns limit its long-term viability. Addressing the review-prompt frequency and uninstallation persistence would stabilize the current user base, but the app remains vulnerable to native iOS feature expansion. **Best for:** Users seeking to reduce eye strain from device usage in dark environments, specifically those utilizing iOS accessibility features. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Deprecate persistent review prompts because they are the top-cited frustration in reviews → improve sentiment baseline ### Outlook: Declining The utility market for screen filters is consolidating around native iOS accessibility features, which are free and privacy-compliant. Luma Sleep's maintenance-mode status and reliance on intrusive UX patterns leave it exposed to further erosion as iOS continues to integrate these features natively. - 🔴 The 157-day update gap suggests the developer has moved to maintenance mode, leaving the app vulnerable to OS-level changes. - 🔴 Persistent review prompts and grayscale persistence after uninstallation drive negative sentiment, which compounds the risk of user churn. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.04/5 | | Total Reviews | 28 | | Sentiment | Frustrated (25/100) | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Luma Sleep – Night Screen** (this app) | 4.04/5 | Frustrated | Sachin Kumar | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | N/A | Cat Connect | | [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 | | [Potatso](https://marlvel.ai/apps/potatso) | 4.4/5 | n/a | Potatso Lab LTD | ## Company Profile - **Developer:** Sachin Kumar ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/luma-sleep-night-screen/id6756083083?uo=4) - **Sources:** 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 - [*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 - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 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 - [*도사폰 (만세력 역학도구)*](https://marlvel.ai/apps/app--656) (Softchaser Company Limited) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Luma Sleep safe to use for my eyes?
