Thank you for writing this — glad Stoolio's earning a spot at your appointments. This is exactly what the PDF reports were built for.

1.2.21
August 30, 2026
Routines restart this month. School, work, the end of summer travel — digestion shifts with all of it, which makes right now the easiest time of year to spot your own patterns. Scan results are rebuilt in this version. Your Stoolio Score reads at a glance, key indicators are grouped so you can go as deep as you want, and every screen loads faster. Notes now save to any scan, including past ones. Log what you ate or how you slept, and a week of scans starts to tell you something. Scan every day through September and see where your score lands.
