1 - Take the guessing out of voting Labour, Lib Dems or the Greens - download the App now! We won't ask you to create an account - no username, password or cookies. Your identity remains unknown to us; we do not ask for your name, address, postcode, email address, telephone number, credit card details or Apple ID / Google ID.
2 - Tell us your sex, year of birth, preferred political party (choose between the Labour, Lib Dems or the Greens only) and constituency. If you are unsure of the name of your constituency, there is a link to a government website where you can look it up from your postcode.


3 - Now tell us to which, if any, of the other two parties you might lend your vote. You can update your constituency (for example, if you move house), your preferred party and your tactical voting intentions at any time but you will always have only one vote.
4 - Now comes the interesting part - the App calculates which of the three parties will gain the maximum vote if everyone who says they will vote tactically actually does so. The result is displayed in a bar chart and the supporting numbers are printed in a table below so there is total transparency. The image displayed is for demonstration purposes only. If you have given us permission to send you notifications when you first download the App, then we will send you one or more notifications prior to a General Election.


5 - It's not just about your constituency. You can inspect the tactical voting intentions in all 650 constituencies. Don't forget to share the App with your family and friends by tapping on the share icon in the top right hand corner of any screen.
6 - You can also look up the results of the 2024 General Election by constituency. This may influence the way you choose to vote.


7 - The App also displays by-election results or if an MP has changed allegiance to a different political party. Prior to a General Election we will display the party policies of the Conservatives, Reform UK and Restore Britain on this website, linked from the App, so that you can make comparisons to help you decide how to vote.
8 - The App requires a decent sample size for the results to be meaningful and a notice to this effect is placed prominently within the tactical voting result page of each constituency. The App assumes all three parties will stand candidates; if they do not we would ask you amend your vote accordingly. If there are still votes displayed for a party for which a candidate is not standing, then we would ask you simply to compare the remaining parties.
The iPhone App is only available from Apple's UK App Store.
Using the App does not guarantee the outcome it predicts.
