I built a free Apple Watch readiness app, and 658 people downloaded it on day one
Push is a free, on-device readiness app for Apple Watch that works with older models, using sleep, HRV, resting heart rate, and strain against a 14-night baseline. In its first 24 hours, it got 658 downloads, over 1,000 product page views, and a 97% conversion rate. The app has no subscription, Pro tier, or health-data server.

score
score 6 out of 10. 0-10: how dense the facts are, multiplied by how much you can do with them after reading. 8+ means the topic's evidence bar is met: benchmarks and availability for a new model, amount and investors for a funding round, revenue figures for a solo-money story. Below 5 an item does not enter the digest. A press release scores 3 or less, a reprint loses 2, anything older than 14 days loses 1, a headline that misleads loses 3.
