Very easy to set up, my LISA transfer from another provider was a bit slow but otherwise painless.  I also opened a S&S ISA with no knowledge of the stock market, very easy and simple and you can select your risk level out of 3 levels (although I can't remember what they were called).  you can see your savings grow and each account has a breakdown.   Only gripe is that you can't wire money to invest/save, you have to manually input how much you want to save in the app (although you can set up auto/monthly payments) and it is taken via direct debit and takes approx 1-2 weeks from the point you add the money on the app before it appears in your balance, only issue with this is that if you do this say 1 week before payday, the amount won't come out until after payday so can mess a bit with finances.    The payday boost is great as you can set a monthly amount to invest/save, only issue with this is that you can only set this up for 1 account therefore I have to manually add money into my other ISA.   Overall a great app but it would be nice if you can wire money so it appears instantly rather than wait 1-2 weeks for it to process.
