Check out Jamovi (www.jamovi.org). This is a free graphical user interface for R (Jos' suggestion). simple ANOVA and Regression designs can be easily analyzed by entering data into spreadsheets and selecting analysis options from menus. You don't need to learn R for this.
Check out R or R based programs like Jamovi (www.jamovi.org) or JASP. I have been using Jamovi after SPSS, jamovi is very user friendly and includes many modules and enough analysis tools for most researchers. Also it do not need any fee. totally free....
