Annoyed that I paid for something that does NOT work

Although this would appear to be a great app to keep track of my INR data, it has many problems. There are only a couple of areas that actually do work. It won’t let me put in even the basic account data. Appointment reminders don’t work, reverts to current time only. Can’t even email for help because it says my email doesn’t work! I’m really bummed I paid for something that is virtually useless!!!

Best INR tracking app

I've sent in feature requests and they've been taken care of. This is the best way to track your INR.

Great app for tracking INR and Warfarin

I've tried some of the new apps that are out there. Some of them have been updated fairly recently. I still come back to OatBook because it's easy to use and doesn't clutter up with unnecessary information. I would really appreciate a graph that isn't cut off at the top. I am one of those people that has an odd up and down reading and many of them get cut off at the high end. I thought if I exported the graph it would be ok but it's cut off there too. Fix that and I would give 5 stars and if I could give more I would!

I've been looking for a good app to track my INR results and my daily warfarin dosage. I finally found with this app! The daily reminders are great since my dosage can be different each day. My only complaint is that the graphing is not very good but there is an option to export to Excel and then I can do what I what to with the data there. If you are on long-term anticoagulant therapy this is the app for you.
