Users report significant concerns regarding data integrity, including the loss of phone numbers and email addresses during the merge process. Given these reports, users should ensure they have a separate backup before using the app. ### Can I use this app for free? While listed as free, the app imposes strict processing limits on non-paying users. Many reviewers describe these limits as a bait-and-switch, as they restrict core functionality for users with larger contact lists. ### What should I do if the app crashes during a merge? Reviewers note that the app frequently freezes or shuts down during large operations. If this occurs, users should verify their contact list against their cloud backups, as the app may have partially processed or deleted entries before the crash. ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
