Feature gaps

Hyper-active development cycle (available in Credit Karma but missing here) +2

Since the last report: The app has matured its feature set with specific differentiators but has slowed its development pace, leading to emerging technical complaints and a reactive maintenance posture.

Bottom line

Amex is the gold standard for premium credit app sentiment, but it is currently operating in maintenance mode while rivals like Credit Karma and Capital One outpace it in development velocity and scale. To defend its position, the PM must fix the 'trusted device' friction and shift from a reactive maintenance cycle to an aggressive feature-led growth strategy.
