Do not buy, its a scam and breaching EU consumer laws.
Disastrous and upsetting experience. The product is far from satisfactory and the scheme is documented being a cheat: “The case emphasizes that EU consumer protection laws, particularly Directive 2011/83/EU and Directive 2019/770/EU, mandate that consumers are entitled to refunds if digital services do not meet expected standards. As the service provider, responsibility lies with you to uphold these rights, even when using third-party payment processors like Apple. If direct refunds through the app are not feasible, you must offer alternative solutions, such as working with Apple to facilitate the refund. A prompt resolution is expected in compliance with EU law.” —So, the producer of this app cashed the money and did zero for correcting it.
