Hypnosis best Apps

Hello i wanted to ask you about recomendatios from good apps for hypnosis that you maybe know.

Since english is not my mother language it would be better for me at spanish or german language.

If someone knows: „HypnoBox“ can please tell me if it is serious and a good app? Did you become improvements and how quickly?

Thank you very much 🙏🏻🙏🏻
