What's a good Android app for keeping tabs on my Amex spending and paying the bill super quick?

Honestly, the Amex app is one of the few finance apps I actually like using. From a technical standpoint, the UI is clean and intuitive – no more spaghetti code situations here. It loads in about 2-3 seconds on my Pixel 7, which is pretty snappy. I can quickly check my recent transactions to make sure everything looks right, and paying the bill is a breeze. The API integration is smooth – basically means it talks to their servers really well. The dev team really thought about the user experience. Barely uses 50MB of RAM, which is awesome. It also lets you redeem rewards directly, which is super convenient. Definitely a well-made app if you're an Amex cardholder.
