What's New in TriLog

4.0.0

October 14, 2026

TriLog 4.0 — the biggest update yet. NEW • Notes view — every note, tracker entry, and dose from the week in one place. Filter by note type, intake, tracker, or trial, or flip to a two-week time-of-day chart. • Forms — log several fields as one entry. Templates for Bowel Event, Pain, Restaurant Review, and Date, or build your own. Every field charts on its own. • Trials — run an experiment on yourself, mark missed days in Day End, and end it Adopted, Dropped, or Inconclusive. • Episode trackers — log a severity, tap Stop when it ends, and see it drawn as a band for as long as it lasted. • Provider Report — a printable PDF of sleep, daily energy, and the trackers and forms you choose, for your next appointment. • Interactive dashboards — export the week chart or your metrics as a self-contained web page. • Trio view — a week chart with the three columns you choose. Also sets the right side of the Day view. • Routines — confirm your daily routines in one tap at Day End. • Intake adds up caffeine in milligrams, and "int coffee" logs from a typed line. ONE PRODUCT, NO TIERS TriLog is now a single app instead of a free version and a separate Pro version. • Try everything free for 30 days. • Then subscribe to keep logging: $59.99/year or $7.99/month. • If you ever stop, everything you logged stays readable and exportable — you're never locked out of your own record. • Already subscribed? Nothing changes. Plus a round of fixes and refinements throughout. Questions, or found something worth sharing? I read every email — support@trilog.app

User reviews

Really helpful as a person with a busy schedule

Really happy to have found this app. It allows me to enter mood and energy multiple times per day + another rating at day end, and then see everything in a couple of screens. I’m using it for writing notes about my day too. It is keeping me more in tune with what’s going on with my life.
