I m in Spain and trying to decide between Trade Republic, Revolut and MyInvestor for investing. I m less interested in which one is best than in what makes an investing app good as a product. For me it s a toss-up between a clean interface, clear fees, and just trusting the company with your money. Revolut has the all-in-one thing going for it, Trade Republic looks like the simplest, and MyInvestor feels more like a traditional bank. For those who ve used more than one, what ended up mattering most to you? And do you prefer everything in one app or a separate one just for investing?

I'm not talking about the obviously ridiculous AI hallucinations. I'm talking about those answers that looked completely believable until someone actually checked the numbers.

Maybe it was a calculation, a misleading chart, or a metric that meant something entirely different from what the AI assumed. What happened, and how did you catch it?
