This app has literally saved my sanity.. I've been so fed up of us running out of money each money but plum works out what it can save for you.. I turned off notifications so I didn't know when it saved money (so I'm not tempted to transfer it back to my account) it's totally free & you can set it to save either high or low amounts but it works it out from your spending/direct debits. Sign up with my link and we both get something ☺️
Have you tried Plum? It saves money automatically, so you don't notice how quickly it adds up - and it's free to sign-up. friends.withplum.com/r/47S4mU
