Author's Evidence Folder
Screenshots from my own watch app and breathwork app that back the figures in my wellness sheet and in the book. The watch screens were taken on 17 October 2026, between 16:11 and 16:15; the breathwork screens on 31 October 2026. The phone's status bar has been trimmed from the top.
How to read these
- This is one person's record, not a trial. It shows what happened to me and cannot show what will happen to you.
- The breath-practice figures come from the Huff app, which counts sessions and minutes; leaderboard places change daily.
- The other figures come from a wrist watch (Xiaomi Watch S5 46mm, read in the Mi Fitness app). Sleep stages, heart rate and blood oxygen are estimates, not clinical measurements.
- The numbers under each picture are copied from that screenshot. They match the rows in the view-only wellness sheet.
- I refresh this folder with the day's screenshots on launch day, 26 October 2026.

Breath practice (Huff app)
Book · Proof of Practice
My practice record in the Huff breathwork app, captured on 31 October 2026 (rankings 16:24 to 16:57, totals and trainer 16:57). Where a leaderboard is shown, the other users' names and pictures have been cut away; only my own row and the totals are kept. A ranking screen can count one session more or fewer than the totals screen.
