This app is a good idea but if you live over 30 minutes away, or it will be longer than 30 minutes before you arrive, its pretty much useless. I live an hour away from my local Great Clips, I checked in as I left home, and was marked as absent. If the app would give you more time, or let you set your own, it would be very handy. The app could be a five star app for those of us that live further out of town. Update: 2/26/2022 the app started locking up my new S22 Ultra. Un/re installed no change
