Im not sure why there are so many negative reviews. I ship with UPS a lot and enjoy their service. This app has done everything Ive asked it to and is also sleek and stylish. It hasnt crashed once. I tracks all my packages and I chose to get push notifications when my teaching status is updated.
It works great for me. Its free, so give it a try before you discredit it from the apparent BS reviews
