I highly recommend staying away from the Eva app. This company uses highly unethical and deceptive practices ("dark patterns") to trick users into hidden auto-pay subscriptions. They deliberately bypass Apple's official In-App Purchase system by embedding an external payment processor (Paddle.net) inside the app. Their checkout layout is intentionally confusing, aimed at making you subscribe without your clear consent while completely hiding the recurring fee structure. To make matters worse, they have built the system to ensure that cancelling the subscription is a nightmare, forcing users into a loop. This is an intentional financial trap designed to drain money from unsuspecting users. I have already reported them to Apple and will be taking steps for a bank chargeback. Avoid at all costs!
