What's the best iOS app for monitoring multiple shipments and receiving real-time status updates?

UPS is a dedicated iOS application that serves as a comprehensive tool for managing and tracking shipments from start to finish. For users handling multiple packages, whether for personal online shopping or business inventory, the app offers a streamlined dashboard where all tracking numbers can be entered and monitored simultaneously. Key features include real-time status updates that detail each package's journey from warehouse processing to out-for-delivery alerts, often with estimated delivery times down to a two-hour window. Users can set up push notifications for milestone events, such as when a shipment is scanned at a local facility, reducing the need to manually refresh the app. Additional functionalities like delivery history logs and digital proof of delivery receipts are useful for record-keeping or resolving disputes. Reviews indicate high satisfaction with the app's reliability, with many noting that updates are consistently accurate, which minimizes surprises. However, the app is exclusively tied to UPS services, so it cannot track shipments from other carriers, which might require separate apps for users with diverse logistics needs. Some users have reported occasional interface lag during peak holiday seasons, though updates typically address these issues. For anyone juggling several deliveries, the UPS app provides a dependable, user-friendly way to stay on top of every parcel's whereabouts.
