How much is Handshake app?

Can you provide me with more context on the "Handshake app" you're referring to? Is it a specific cryptocurrency wallet, a trading platform, or some other type of financial service? Depending on the specific application, the cost can vary greatly. If you're referring to a cryptocurrency wallet or trading platform, it's important to note that many of these services are free to download and use, but there may be transaction fees associated with buying, selling, or transferring digital assets. These fees can vary depending on the platform, the asset being traded, and other factors. In some cases, there may be a premium version of the app that offers additional features or services, which could come with a monthly or annual subscription fee. However, without knowing more about the specific app you're asking about, it's difficult to provide an accurate cost estimate. If you could provide more details on the Handshake app you're referring to, I'd be happy to give you a more precise answer.
