ZzzTape review for Personizely: A/B Testing & CRO

May 18, 2026

We tested multiple CRO apps and Personizely ended up being the best. Both from functionality of the app as well as their team's service and responsiveness. User interface is clean and intuitive. We were able to conduct multiple tests that raised our CRO and made a material difference to our bottom line. Special shoutout to Sergiu on their team that helped when we had a tracking question, which he resolved within minutes.
