Pros - cheaper than HL, serviceable app, take ownership of customer issues, send out lots of research. Cons - app layout could be better and has no dark mode still. Fund prices very very slow to update - HL are over 12 hours ahead, can't cancel a trade placed in error even if it was done night before (HL enables you to cancel until 8am on day of trade).

Very easy to trade and see holdings. I have multiple accounts (trading, ISA, two junior ISAs) which are all managed through the one login. Trading features are complete enough for my needs ( Buy, Sell, Limit to buy/sell, UK and US markets, funds). One helpful feature is that displays your average for that holding so you don't have to work it out yourself. I'd love for it to have a widget for my homescreen to display up to date prices. I have to use a different app for that at the moment

...app does what it's supposed to but it keeps logging me out every so often and expecting username and password to log back in (even though i have fingerprint login) ...i understand this may be a security thing but why is it necessary when you have biometric login enabled (none of my other banking or investment apps do this)
