Bondbell is an independent app for checking UK Premium Bond numbers against the monthly prize lists. Save your bond ranges once. When you tap Check, it downloads NS&I's public list to your phone and compares it with your numbers there. Your bond numbers are never sent anywhere.
There is nothing to sign up for. Bondbell keeps your bond numbers on your device and only goes online when you ask it to, to fetch the public lists NS&I publishes.
Open My bonds, add a holder, then enter the bonds as ranges or single numbers, from a statement or from old paper certificates. Spaces are fine. If a number cannot be read, Bondbell explains why in plain English.
Bondbell shows the size of the list before anything downloads. It then downloads the list straight from nsandi.com, compares it with your numbers on the device, keeps only the matches and deletes the download. You can cancel at any time.
The result lists any prizes by holder, or says plainly that none of your bonds is on that month's list. Every result reminds you to confirm with NS&I, and when prizes are listed it explains how to claim them.
There is nothing to register and no password to remember. Your bond numbers are saved on your device and the comparison happens there.
Add bonds as ranges or one at a time. Old paper certificates work too, and a holder can have as many ranges as you like.
Search NS&I's list of prizes that were never claimed, which goes back to 1957. The list shows the value of each unclaimed prize, and claims are made through NS&I.
Turn on an optional reminder at 9am UK time on the day new results are expected. It tells you the new list should be available. It does not tell you whether you have a prize.
Sample mode runs a complete check with made-up numbers, so you can see how it works before adding your own. Sample data is clearly labelled and kept apart from your real bonds.
No advertising, no analytics and no server of ours in the middle. Purchases are handled by the App Store or Google Play. You can delete your bonds and results from Settings at any time.
Bondbell is for anyone who would rather not log in each month, and for families sorting out bonds that have sat in a drawer for years.

Open My bonds, add a holder, then add each block of bonds as a range (first and last number) or as a single number. You will find the numbers on a statement or on old paper certificates. Spaces and separators are fine.
Two letters followed by six digits, usually with up to three digits in front, in the pattern 123AB456789 (a made-up example). The oldest bonds have no digits in front. The letters I, O and U are not used, so Bondbell will ask whether you meant 1 or 0. A range has to stay within one series: the same leading digits and letters.
The most common reason is that a holder's number has been typed instead of a bond number. The message says what is wrong, such as too many digits or a letter that is never used.
No. A check runs only when you tap Check. The optional reminder tells you when a new list should be available; you then open the app and check when it suits you.
Only that new results are expected that day, at 9am UK time. It is one notification a month and it does not know or say whether you have a prize. Turn it on or off on the Check tab or in Settings. Bondbell asks for notification permission only when you turn it on.
The latest draw is free. With Pro you can check any of the months NS&I currently publishes, usually about six.

Confirm it with NS&I. The result screen explains how prizes are normally paid and links to NS&I's own contact page and prize checker. Bondbell cannot pay, claim or confirm a prize.
