It holds a 4.67/5 rating from 12 reviews. > **Bottom Line:** Master Clean Duplicate Contact relies on a simple cleanup utility that currently lacks a monetization path. Introducing a premium tier or IAP would capitalize on the existing positive user sentiment and provide the resources needed to resume development. **Best for:** Smartphone users with disorganized address books who require a simple tool to consolidate and clean contact information. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit current user base for monetization potential because the app is currently free with no IAP gates → unlock revenue stream ### Outlook: Mixed Users report: The contact utility market is increasingly dominated by OS-native features, leaving Master Clean Duplicate Contact exposed. Without a clear monetization strategy or feature expansion, the app will likely see declining relevance as users migrate to built-in tools. - 🔴 The 10-month development gap suggests the app is in maintenance mode, which risks obsolescence as iOS contact management features evolve. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.67/5 | | Total Reviews | 12 | | Sentiment | Thrilled (90/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 4 analyzed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Master Clean Duplicate Contact** (this app) | 4.67/5 | Thrilled | duytu tran | | [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:** duytu tran ## Data Sources & Links - **App Store ID:** 1331319905 - **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 - [*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 Master Clean Duplicate Contact free to use?
