I love that we can do 1x 2x 5x 10x for roundup, but having a custom option would be so much better. I am on 2x but I’d like to try out 3x or 4x. 5x is just too much for me personally.
Similarly with the 1p challenge, I am doing the 4p, but being able to change it to let’s see 5p or 3p or a different amount would be super helpful.
Yes! Let me 100x the 1p challenge for as long as I’m able to maximize that sweet 5% interest… 
I started with the roundup but then found that it too got a bit too easy too. So I switched to saving by depositing a fixed amount into a pot each week/month with a scheduled deposit and kept building up from there. Now it’s my investment fund
