The right credit card for you — no account, no internet.

An app that helps you pick the right credit card before applying. A seven-question survey builds the profile, the app ranks the catalogue by fit, estimates an educational credit indicator and puts two options side by side. Everything runs on the device: no sign-up, no server and nothing sent anywhere.

• A 7-question survey that resumes where you left off
• Catalogue ranked by fit from 0 to 100
• Educational profile indicator, with tips on how to improve
• Side-by-side comparison with per-criterion highlights
• Letícia, an on-device assistant with no external AI
• Works offline, with no account and no data collection
