The client faced a severe retention issue. Users were downloading their previous app but abandoning it after 3 days because manual entry of expenses was too tedious. They needed a seamless, automated way to track finances without compromising bank-grade security.
We engineered a secure middleware using Plaid for real-time bank connections, ensuring users never had to manually input a transaction again. We paired this with a Flutter frontend for 60fps performance on both iOS and Android, and implemented on-device encryption to ensure user data never touched our servers unencrypted.
