MobileGuard helps you observe your iPhone’s network behavior and identify signals that may deserve attention through time-limited VPN analysis sessions started voluntarily by the user. TRAFFIC MONITORING AND ALERTS During a session, MobileGuard analyzes traffic metadata and the ratio between data sent and received. Persistent upload activity while the phone is idle, small frequent transmissions, or sudden outbound spikes may indicate unusual synchronization, automated activity, or potential data-exfiltration patterns. Indicators are checked against international threat-intelligence datasets to highlight potentially malicious destinations, infrastructure associated with malware or Command & Control servers, and behavior compatible with spyware. MobileGuard generates alerts and a security report to help you understand the detected destinations, volumes, timing, and risk level. An anomaly does not automatically prove that a device has been compromised. Modern apps communicate in the background and can produce legitimate variations. MobileGuard highlights trends and indicators that may require further investigation instead of drawing conclusions from a single event. PRIVACY BY DESIGN Analysis is limited to the technical and security metadata required to provide the service, such as destination IP address and port, protocol, hostname when available, country, session timing and duration, traffic volumes, and risk indicators. MobileGuard does not inspect or store packet payloads, messages or communication content, passwords, payment-card data, full URLs, or URL parameters. Navigation metadata is used exclusively to identify potentially malicious destinations or anomalous traffic and to generate the alerts and reports requested by the user. The VPN session metadata required to provide the service is stored on MobileGuard servers. It is not sold, used for advertising or profiling, or shared with advertising networks, data brokers, or analytics services. If notifications are enabled, Firebase is used only for delivery and receives no VPN data. MobileGuard is a professional network-security analysis tool. Its report can be reviewed by cybersecurity experts to evaluate the context and assess whether the detected connections are legitimate. YOU REMAIN IN CONTROL You decide when to start an analysis session and can stop it at any time. Ten-minute analysis units are available as a consumable in-app purchase. From Settings, you can review the VPN disclosure, manage purchases, sign out, or permanently delete your account and associated data. MobileGuard provides security indicators and analytical support. It does not replace antivirus software, a forensic examination, or advice from a qualified security professional.

Verdict
The clearest difference is update cadence: Mobile Guard Sentrynet at daily against Orion Sentry's weekly. Orion Sentry's advantage is device support (3 vs 1) and iOS requirement (18.5 vs 26.0). On price, ads and in-app purchases there is nothing between them.
