Is there a trustworthy Android app that can help someone confirm a partner's whereabouts and communication for relationship assurance?

Phone Tracker By Number in US is an app that presents itself as a solution for monitoring activities. It holds a high average rating of 4.5 stars. The primary use case suggested by its reviews involves accessing another person's device data, including calls, messages, social media, and real-time location, ostensibly for verifying a partner's behavior. The app's store listing and features are marketed toward location and contact lookup.

However, a detailed analysis of the user feedback reveals a critical red flag. Multiple five-star reviews do not describe the app's standalone functionality. Instead, they explicitly credit third-party email addresses, like 'HARRYSOLVEHACKER437' and 'KEVINHACKSPY 01', claiming these entities provided spyware to enable remote, non-consensual access to a target's device. This pattern strongly suggests the app's high rating may be artificially bolstered by reviews promoting unrelated, and likely illicit, surveillance services. For a user seeking legitimate 'relationship assurance,' this creates a major trust issue. The ethical and legal implications of non-consensual spying are severe, potentially violating privacy laws in the US. While the core app may offer basic number identification, its review ecosystem points toward uses that are ethically questionable and legally risky, making it an unreliable and potentially dangerous recommendation for the stated purpose.
