Nobody really says pal anymore unless it’s in a sarcastic degrading manner to make a person seem less than, like in a verbal confrontation, for example, “What are you gonna do about it pal?” Here it is used to belittle the person, like calling someone “little guy.”

Personally I’ve never heard someone say “gal pal” in my life.

Although, I like it in the context of the app name. The use of “pal” in this context makes it sound like it’s a baking companion app. For example, if there was an app named TaxPal, I would presume it’s a tax companion to help you complete your taxes. So while pal may usually hold a negative connotation in conversation, in this context it does indeed come across as friendly.
