Great..a few tweaks and it would be awesome. Would love to be able to set price alerts from the app. More stock info when you expand a ticket like you can with Hargreaves Lansdowne or you see if you look at it via a browser Really really would love to see 1 Week price graphs. Currently you get 1 day, 1 month, 3 month, etc. you can on a browser. why can't you in the app?

generally poor app. cannot do screenshot despite no permission restriction on camera. Certain items got to be 'transferred ' back to a main web site which keeps saying password not accepted. the worst of all, only 1 day or 1 month chart, no 1 week charts. then fees for each fund cant be seen until you pretend to trade... learn from HL which is much more user friendly !

Very difficult or impossible to update basic account details such as phone number. Had as much effort been put into allowing easy navigation as has been put into selling updates and getting new accounts the app would be fantastic, sadly it is not. security is very important but there comes a point when the security is so cumbersome that it is time to use a different company.
