Most of this book can be read without relying on any specific statistical software. However, some parts explicitly mention and refer to jamovi (The jamovi Project) and/or SPSS (IBM Corp 2016). jamovi is free and is like (but not exactly the same as) SPSS. From the jamovi homepage (sic):
jamovi is a new ‘3rd generation’ statistical spreadsheet. designed from the ground up to be easy to use, jamovi is a compelling alternative to costly statistical products such as SPSS and SAS.
