I'd want to see this data before committing to Zen. The Health & Fitness space has alternatives that outperformed it on engagement ratio, and a few that launched in the past six months with fresher approaches.
The numbers below come from launch data. No pay-to-play, no editorial picks.

A product that pulled 500 interest in 2022 faced a different competitive landscape than one pulling 500 in 2026. The bar rises every year as more products enter every category. Compare products within their year cohort, not across years.
Engagement ratios are more stable across time periods. A 0.40 engagement ratio meant the same thing in 2022 as it does now: people cared enough to discuss it at length.
Frequently Asked Questions
We pull new launch data regularly and rebuild the entire index. Historical scores are preserved. A product's launch-day numbers don't change retroactively, which keeps the rankings honest.
Because interest score measures initial attention, not quality. A 300-interest product with 0.50 engagement ratio has a small, obsessed audience. That's usually a better sign than 3,000 interest with 0.08 engagement, which screams 'great marketing, thin product.'
The index tracks launches automatically. If something's missing, it either launched below our engagement threshold or hasn't been indexed yet.
Primary target audience at launch. Some products serve both. We classify based on who the product was positioned for, not who ended up using it.
We're working on it. Right now, the index captures launch data and community metrics. Direct product links are coming in a future update.
