Wanted to see what their fuss was about. Immediately canceled and deleted the app in one day. Double checked on my subscriptions to make sure it was canceled and yet five days later, I am still unable to find a way to get rid of their notices and demands for payment schedule! And no easy way to get rid of these notifications for a deleted app maybe they are fine for you, but it was not for me and just seeing the persistent demand for purchase is totally unacceptable
Dear user, it is not possible to receive any notifications/purchase from the app once the app is deleted. Please ensure the correct app is deleted- let us guide you, please write to us at heartratebp@gmail.com and we'll help you out.
