Great App
I have tried several apps for this purpose & this one is by far the most accurate. It is also very easy to use. Copy the tracking info, open the app, then click the + icon, & most of the time all else is automatic. You can also label ea. one so if you have several at a time you can tell them apart from ea. other w/o having to open ea. one individually. Great app!
