"Adapty's platform makes it easy for non-developers to create and manage A/B tests, paywalls, product mix and pricing structure. They have a great external API that makes it easy to pass related events to other analytics tools like Amplitude and Mixpanel."

“We’ve tested more than three hundred paywalls in the space of four months. Adapty allows testing basically any element of the paywall, and we took advantage of that. We’ve tested them all: products, title text, CTA buttons, images, videos etc. With Adapty’s A/B testing, we managed to double our monthly revenue. I wasn’t sure if one instrument could make such an impact, but I witnessed it myself.”
