Trading 212 isn't app-only, the web interface is pretty good. They are 'no fees', monthly or on trades, but obviously taking their cut on the spread.I think you may have misunderstood I meant websites for opening a trading account. I've only looked briefly into things and I see that td Waterhouse who I used previously was taken over by ii.co.uk interactive investor, but I keep seeing places like etoro and trading212 which if probably shy away from as I'm not keen on an app only platform.
Edit
I'm not going to be investing big to begin with so I guess fees per trade and monthly fees probably need to be fairly low if I'm not going to be doing big investments to make it worthwhile.
I think for small amounts these platforms are probably hard to beat.
