Hi @cpd54, Part of the program is an app available in the Google Play Store for Android mobile devices and phones and also available in the Apple Store for iPhones and iPads. You may be able to enroll in the program without using the app but I'm not sure. It looks like the app is used to communicate with your healthcare team as well as track some of your health data.

"The RevUp app is a companion to this service that allows you to communicate with your health coach, set and track your health goals, and easily log your health vitals."

Here's information from the company that produced the app:

@cpd54 My nephrologist office wanted me to join a service similar to what you have been invited to. With everything I have going on already, I wasn't keen on doing that. And, truth be told, I am not a techy person. So, having to log in and do different reports, communications just wasn't in my interest. They tried twice to convince me, then I told them to stop calling.

Hi, @cpd54, I've never used or heard of that program, but on the website you linked to I read, "Our program has no contract or obligation, and you can cancel at any time by messaging your RevUp nurse, emailing support, letting your health coach know, or giving us a call at 866-716-0083 Mon.-Fri. between 8 a.m. – 5 p.m. Pacific Time."
If that information is accurate, then if you try it and decide it's not for you, supposedly canceling ought to be fairly easy.
