PerkBook

Stop leaving money on the table. Most credit card holders forget to use the credits and perks they're already paying for. PerkBook fixes that — it's the simplest way to track every benefit across all your cards and make sure you're getting full value from your annual fees. Track every credit. Add your cards and PerkBook knows when each credit resets — monthly, quarterly, or annually. Mark credits as used, and the app tracks your progress for every period. Never wonder "did I use my dining credit this month?" again. Get reminded before credits expire. Set notifications days before a credit resets and PerkBook will remind you when it's time to use it. Choose a primary reminder and an optional follow-up so nothing slips through. See the full picture. The summary view shows every benefit across all your cards in one place — what you've used, what's remaining, and what's expiring soon. Filter by active, redeemed, or expired to stay on top of everything. Optimize your spending. The Strategize tab helps you figure out which card to use for each spending category based on your monthly habits, so you're always earning the most from every purchase. Built for serious cardholders. Whether you carry two cards or ten, PerkBook scales with your wallet. Supports credits that reset on your card anniversary or the calendar year, variable credits, access perks like lounge access and hotel status, and more. Your data stays private. Everything is stored on your device. No account required, no data shared. PerkBook is not affiliated with any credit card issuer. Benefit values are entered by the user and may not reflect current card terms. Always verify benefits directly with your card issuer.
