I frequently order products on behalf of my clients and I want to be notified of their shipping progress and when they are delivered. Delivery Status lets me do this easily. Initially, I used the free Delivery Status widget. When I received a vendor’s email with a tracking number, I’d add this item to the Delivery Status widget. It can track packages from USPS, DHL, Fedex, OnTrac and many other shippers. Delivery Status would then send me status updates via Growl every time the package made progress towards my door. This was great, but I realized I only got updates when my Mac laptop was awake and connected to the Internet. Sometimes I wanted to be notified in the middle of the day as I was moving between client appointments. Consequently, I decided to buy the iPhone/iPad Delivery Status app ($5). Now I get notifications on my iPhone since this app can sync with the widget if one sets up a free account at the JuneCloud web site.
[Update February 2017: Delivery Status is now called Deliveries]
I’ve been using DeliveryStatus for about a year and have been very pleased with its performance. Check it out.
