Canadian churning rules, tracked
RBC 1/90. TD 1/90. Amex once-in-a-lifetime. Chase 5/24. CardSignals counts the days so you never waste a welcome bonus on a card you're not eligible for yet.
You already have 3+ cards. CardSignals tells you which one to use.
The Canadian-first rewards optimizer for churners. It knows the best card for every purchase, tracks every welcome bonus, and watches the Canadian rules US apps ignore.
Founding members lock in lifetime pricing. First 500 only. No spam.
You carry premium cards and still tap the wrong one at checkout.
Those rewards are already yours. You are just missing them.
Built around how Canadians actually earn rewards
Amex Canada offers, activated for you
No US app does this. The CardSignals Chrome extension adds every available Amex Canada offer to your card automatically, the moment you land on the Amex site.
Your rent, finally earning
The biggest cheque you write each month should not earn nothing. CardSignals routes your rent through the right rail, Casa, Chexy, or direct, for your card and your province.
Lock in founding pricing — for life.
The first 500 members get a permanent founding rate. Once you are in, that price never changes. We will email you the moment founding access opens. No spam, no launch-day hype, just one message when it is live.
What is CardSignals?
CardSignals is a Canadian-first credit card optimizer for people who carry more than one card. If you hold cards from RBC, TD, Scotiabank, BMO, CIBC, or American Express Canada, alongside the US cards Canadians actually use, like the Amex Platinum or Chase Sapphire, you are almost certainly using the wrong card for some of your spending.
CardSignals fixes that. It tells you the best card to use in every purchase category, tracks your welcome bonus progress so you never miss a minimum spend, and counts down Canadian application rules like RBC's 1/90 and Amex's once-in-a-lifetime restriction. Its Chrome extension activates Amex Canada offers automatically, something no US-built app does, and its Rent Payment Optimizer routes your rent through the rail that earns the most for your card and province. Built for Canadian churners and rewards optimizers, with all data stored in Canada.
