Stop leaving money on the table. If you have premium credit cards, you're paying real money for real benefits — but most people use less than half of what their cards offer. Perksly is a private, on-device tracker that helps you actually use every credit, every perk, every month. WHAT PERKSLY DOES • Tracks monthly, quarterly, semi-annual, and annual credits across your wallet • Shows what's Available, Used, and At Risk of Expiring at a glance • Sends smart reminders before credits expire so you don't forget • Logs always-on perks (lounge access, elite status, insurance, no foreign transaction fees) • Built-in catalog of 200+ U.S. credit cards from major issuers • Catalog updates automatically as new cards launch and benefits change INSIGHTS THAT MATTER Slice your wallet's value by card, by category (dining, hotel, airline, transport), or by issuer. See which benefits you've earned this period and which you're at risk of losing before they reset. PRIVATE BY DESIGN Perksly stores everything on your device. No accounts to create, no data sent to our servers (we don't have any), no analytics, no ads, no tracking. Your card information never leaves your iPhone. FREE TO USE Perksly is free, with no ads and no tracking. Just an app to help you get the value you're already paying for.
