A number of credit cards have apps/websites with recurring charge trackers. As much as I love credit unions, they don't do 2-5% cashback, so it can be wise to stack recurring payments onto credit cards for benefits.

HSBC in the UK does something like this. It detects the regular monthly outgoings from your account, like bills paid by Direct Debit or other regular payments, groups them by whether they’ve been paid yet this month or not (based on the date that you entered as your payday) and estimates what your remaining bank balance will be after the bills are all paid.

ABN Amro does this. Their app automatically groups expenses into categories and is able to identify recurring costs.

Amex does this and will alert you when it finds a new recurring charge.
