My biggest problem with this app is that they deliberately make it hard to cancel your subscription. Managing the subscription is not an option in the Setting section which is where it should be. Why isn't it listed there? In addition, there is an actual Payment settings section within the Settings Section, which again; does not let you manage your subscription, it only lists your payment email address. These efforts to bury the Manage your Subscription option are without a doubt by deliberate design and in my opinion shows a lack of transparency that is usually found with apps that lack true credibility.
