The important thing is to check that your broker is covered by the £85k FSCS guarantee. I would imagine all the major brokers are, I'm with IG who are covered.
My understanding of commission free trading apps is they are usually screwing you on the spread or they are using your capital for hedging, shorting, etc. I've never used one myself but if something's too good to be true it usually is.
