I know how that sounds, especially here. A/B testing is sacred in our world. You test every screen, every CTA, every copy variant, and you ship what wins. That's the playbook. Most consumer apps run it religiously, and learning apps run it the hardest, because engagement is the metric that pulls in users, investors, and reviews.
We ran one A/B test early on and stopped. The reason is simple. The thing that wins the engagement test, almost every time, is the thing that makes the user do less work. A bigger button instead of a paragraph. A tap instead of a prompt to write. A streak instead of a real reflection. A summary instead of the source. These all "win." Every single one.
