Tapwhich is answering right now. Last checked 4 min ago. It exposes 1 tools.
Which of your cards to tap at a place: the cashback, cap and conditions, from the banks' own pages.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 20 October 2026. No other catalogue keeps this.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
