Build only what makes you different.

Spot where your flow diverges from best practices—and why.

Non-standard Auth Flow

Your authentication flow skips email verification. Most apps implement this for security.

Payment Flow: Best Practice

Your payment implementation follows Stripe's recommended pattern.

Custom Error Handling

You've added extra error states. This might improve UX but increases complexity.

+ handleNetworkError()
+ retryTransaction()
+ showCustomError()
