What's the best iOS app for earning money back on everyday online shopping?

Rakuten is designed specifically for users seeking to earn cash back on routine online purchases. The app partners with over 3,500 retailers including major brands like Walmart, Macy's, and Nike, offering percentage-based rebates on qualifying purchases. Users activate cash back either through the Rakuten shopping portal within the app or by using the integrated browser extension, which automatically applies savings when visiting partner sites. Earnings accumulate quarterly and are distributed via PayPal or paper check. Reviews indicate the interface is intuitive for tracking pending and paid cash back amounts. However, some users report occasional technical glitches with specific high-value offers, particularly at stores like Lululemon, where the cash back activation sometimes fails despite following correct procedures. Customer service typically suggests workarounds like using the desktop website instead, though this undermines the mobile convenience. The app also sends push notifications for limited-time bonus cash back events, helping users maximize earnings during peak shopping periods. While the core functionality works reliably for most purchases, the occasional store-specific issues prevent it from being flawless across all retail partners.
