Does MaxRewards require linking your bank?
Yes, for the features most people sign up for. MaxRewards connects to your issuer accounts to auto-activate offers, sync balances, and run its Benefits Tracker on Gold. CardStack takes a different path: you can add cards and track credits manually on the free tier with no bank connection. CardStack+ adds optional Plaid sync for automatic credit detection and spending analysis.
Which app is better for tracking statement credits?
A statement credit is a reimbursement your card issuer applies when you make an eligible purchase (like the Amex Platinum $200 airline fee credit). CardStack is built around premium card credits: reset dates, partial redemptions, expiring reminders, and net fee offset that shows whether your annual fee is covered. MaxRewards has a Benefits Tracker on Gold, but its core strength is offer activation, not deep credit lifecycle tracking.
What does MaxRewards do better than CardStack?
MaxRewards auto-activates offers across more issuers (Amex, Chase, BofA, Citi, Discover) without you opening each app. It also auto-activates rotating bonus categories on cards like Chase Freedom Flex. It supports Android, includes credit scores and bill tracking, and has a large member base. If those are your priorities, MaxRewards earns its Gold subscription.
What does CardStack do better than MaxRewards?
CardStack works without linking a bank on the free tier. With CardStack+, Plaid sync auto-detects statement credits from real spending. CardStack shows earned vs missed rewards per purchase, calculates whether each card's annual fee is worth it (net fee offset), and includes Ask Stack, an AI assistant for your specific wallet. Chrome and Safari extensions surface the best card while you shop and can enroll Amex and Chase offers.
How do the prices compare?
As of June 2026, MaxRewards Gold starts at $108/year (pay-what-you-want sliding scale). MaxRewards Platinum starts at $240/year for business spend tools. CardStack+ is $69.99/year or $7.99/month after a 7-day free trial. CardStack's free tier includes manual credit tracking; MaxRewards Bronze is free for basic card viewing.
Who should use which app?
Use MaxRewards if offer auto-activation across every issuer is your priority, you want rotating category automation, you need Android, or you want credit scores and bills in the same app.
Use CardStack if you carry premium cards, care about statement credits expiring, want annual fee ROI from real spending, and prefer not to link a bank until you choose to. Many people use both: MaxRewards for offer activation breadth, CardStack for credit tracking and fee math.
Frequently asked questions
Is MaxRewards worth it in 2026?
