Ratings and Reviews

More functionality needed

The app is presented well, and in order to set it up you have to put in all your bond and security details. But it only tells you if you’ve won a prize. The app can be so much more, what I would like to see if full functionality like a online banking app. Where you can see your holding and the amount, pay in and withdraw and make account amendments. For a big corporation this ease of access should be at the forefront. It’s annoying having to go online and manually enter all my details when I already use Touch ID to access my bond prize checker!!!

Of historical interest only ..

As other reviewers point out, all this app aspires to do is check if youve won a prize – something youd only need to do if you (a) think NS&I wouldnt automatically tell you about a win
(b) you found some old Premium Bond details that predate your last house move/email address change and therefore think NS&I might have sent the automatic notice to an old address.
(c) you are insanely optimistic and think the Fickle Finger of Fate has increased the randomisation factor on the selection of Premium Bond winners to the point where non-bond holders can win prizes.
Other than that, its just taking up space on your device, which is a shame because the NS&I website is such a great example of a site with the combination of minimum necessary functionality and strong security capability that its hard to believe this app comes from the same organisation.

More helpful than trying to phone

Somehow locked myself out of my account over 3 months ago. My attempts for help over the phone prove to me that I know more than the people that answer the phone. I am still not back on. I am not UK based which means my password is caught up in the COVID/Brexit mail backlog.

When I wailed that I knew I had won (from the emails) but could not find out how much, they could have easily told me to use this app. It is great, does not help me access my money but it tells me what I have won. I only have a couple of £25 prizes - but at least it means I am not dreaming of my unknown thousands.
