Advice Needed Learning to play the guitar, advice?

Hi everyone.

I'm learning to play the guitar recently and just learned my A and D chord. I've been using Justinsguitar, but can't really proceed because my fingers are starting to hurt like hell.

Does any guitar players have beginner's advice that'd be helpful in the future or now?

ALSO

Is it worth using apps like Yousician etc?

I recently started playing the violin and a tip I can give you is practice every day. Even if it's a little bit, do it. Also always search little songs or exercises to do so you can keep improving. My fingers also hurt a bit after moving them over the strings after a time but you gotta get used to it.
