The USPS® Rapid Drop app is a companion to the USPS® Rapid Dropoff Station (RDS) kiosk. This free app allows you to reduce time at the Post Office™ by preparing shipping label information in advance or easily drop-off multiple packages at once by creating Dropoff Groups. • Create a Dropoff Group* – Use the in-app scanner to consolidate multiple printed shipping labels into a single Dropoff Group for self-service package acceptance. Scan your generated Dropoff Group code at the Rapid Dropoff Station, select your receipt option (printed or emailed), and drop your packages in the parcel drum or at the Retail counter. All packages in your Dropoff Group will receive an acceptance scan. • Start a Label – Shortcut package label creation at the Post Office™ by prepopulating the label shipping information in-app and presenting the Label Broker® code at a Self-Service Kiosk (SSK) or the Retail counter for completion and payment. • Add a QR Code – Store your Label Broker® codes in one place for easy accessibility and label printing at the Rapid Dropoff Station, Self-Service Kiosk, or Smart Parcel Locker. • Track a Package – Easily track your Dropoff Group packages and import additional Tracking Numbers from other shipments using your receipts. Allow push notifications to receive near real-time updates. • Locate a Post Office™ – Search for Post Offices near you and see their hours of operation, available technologies, and service offerings. *This feature is currently only available at locations with a Rapid Dropoff Station

Verdict
The clearest difference is update cadence: Ultron IMS at every 2 weeks against USPS® Rapid Drop's every 10 months. Ultron IMS also leads on iOS requirement (15.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
