I first saw “Safe-to-Spend” as an idea from Simple, it’s their trademark. Check what they did to our friends even before launching!
Now I think Monzo uses this concept anyway somehow in a summary page as “left to spend”. I’m not sure because I’m not using Monzo (for other reasons against my will, I really love Monzo!):
I’m researching about this feature and I KNOW I’ve seen it at least a couple of other challenger banks/neobanks, but I can’t remember which ones.
Do you know which ones? Help!
