Which investing app is best for total beginners in 2025?

Hey everyone!

I'm finally ready to start investing some of my savings (about £200/month to start), but I'm totally lost on which app to use. I've been watching some YouTube videos about investing for beginners, and there seem to be so many options.

I basically want something really simple and beginner-friendly where I can invest in index funds (I think that's what they're called?) and maybe some individual stocks once I learn more.

My main concerns are:
- Easy to use
- Low fees
- Good for small regular investments
- Safe/reliable platform

Would really appreciate any recommendations, thanks in advance!
