There’s no one-size-fits-all app stack, but a few CRO tools consistently help improve conversions. For email capture and exit intent, Privy or Justuno does the trick. Klaviyo helps with personalized email flows that bring customers back. ReConvert can make your thank-you page do more heavy lifting, and Judge.me is a go-to for adding social proof with reviews. If you want to build urgency? Try Fomo or Countdown Timer Bar. And for conversion optimization and A/B testing, there’s no better tool than Fibr. Just don’t go overboard; too many apps can slow down your site.
