Those with a Chase Freedom credit card can earn 5% cash back on up to $1500 in combined purchases during the first three months of 2018 when you use your card with Apple Pay (along with competing mobile wallets Chase Pay, Android Pay, and Samsung Pay). You’ll have to activate the cash-back bonus on Chase’s Web site.follow link

Chase Freedom Offers 5% Cash Back for Apple Pay Usage
To clarify, it’s 5% back on purchases up to $1500, so the maximum cash back is $75.
So basically the same as DiscoverCard 5% cash-back (they pick new categories every quarter) or US Bank's Cash+ 5% cash back (you pick new categories every quater) except those work regardless of whether you use ApplePay or not - of course I use ApplePay whenever I can.
