TriLog is the personal data logger. Capture mood, energy, focus, and symptoms in seconds — then see how they line up with sleep, weather, habits, and everything else on one timeline. Most trackers ask once a day how you felt, then average it. But the crash hits at 2pm. The migraine lasts four hours. The good morning follows a bad night. TriLog records moments, not daily summaries: every entry has a time, and a whole week sits on one screen, hour by hour. Built for people who already track seriously — energy you have to budget, symptoms nobody can explain, experiments you're running on yourself — and who have outgrown mood journals, spreadsheets, and scattered notes. NEW IN 4.0 • Notes view — every note, tracker entry, and dose from the week in one place. Filter it, or flip to a two-week time-of-day chart. • Forms — log several fields as one entry: a pain episode, a bowel event, a restaurant visit. Start from a template or build your own. • Trials — run an experiment (magnesium, no afternoon coffee), mark the days you missed, then end it Adopted, Dropped, or Inconclusive. • Episode trackers — a headache with a start, a severity, and a stop, drawn as a band for as long as it lasted. • Provider Report — a printable PDF of your sleep, energy, trackers, and forms to bring to an appointment. • Interactive dashboards — export the week chart or your metrics as a web page and explore months on a big screen. • Trio view — a week chart with the three columns you choose. CAPTURE IN SECONDS Capture has to be effortless or it won't survive a hard week. • One tap each for mood, energy, and activity • Quick Track — leave it open and log with single taps • Type a line — "t hd 3", "int coffee" — with your own shorthand • Siri — "energy 3", "mood sad" • Long-press any chart to log at that time; drag a marker to re-time it EVERYTHING ON ONE CLOCK Your entries sit alongside weather, barometric pressure, pollen, air quality, and daylight; Apple Health sleep stages, HRV, resting heart rate, steps, and workouts; and hour-by-hour Screen Time. Did this week feel worse because of sleep, pressure, screen time, or something you took on Tuesday? WHAT YOU CAN LOG • Mood, energy, and activity throughout the day • Notes — meals with calories, health, journal, cycle • Trackers — ratings, numbers, choices, episodes, traffic lights, titled ratings • Intake — coffee, supplements, medications, with caffeine totaled in mg • Day Launch and Day End — sleep, goals, reflections, routines • Habits — daily checkmarks, no streaks, no scores SEE WHAT LINES UP • Week chart — seven days, twenty-four hours, one screen • Day view, Notes view, and Trio view • Journal — your journal notes and Day End reflections, collected day by day with photos • Metrics grid — sleep, energy, weather, steps, trackers, and trials by day • Analysis — patterns, day ratings, correlations, intake and cycles against your ratings • Free, open-source Mac and Windows viewer PRIVATE BY DEFAULT No account. No third-party servers. No ads. Your log lives on your device, with optional iCloud backup. Export everything, anytime. ONE PRODUCT, NO TIERS Try everything free for 30 days. Then $59.99/year or $7.99/month to keep logging. Cancel during the trial and pay nothing. If you stop subscribing, the app becomes read-only — everything you logged stays browsable and exportable. Demo Mode (Menu → About) lets you explore with sample data first. A LOGBOOK, NOT A DOCTOR TriLog records and displays. It does not diagnose, treat, or give medical advice.

Every other tracker punishes you for missing a day. Logbook doesn't. No streaks to break. No red X's. No guilt. Just a quiet, private place to log what you actually do — and see the patterns for yourself. TRACK ANYTHING THAT MATTERS TO YOU Workouts. Meditation. Mood. Sobriety milestones. Medication. Intimacy. Sleep. Water. Whatever you want to understand better about your own life — the ordinary stuff and the deeply personal stuff. WHY PEOPLE STAY • One tap to log — two if you want the details • Track it your way — toggles, numbers, durations, multi-select options • Forgot yesterday? Backdate any entry, anytime • Real insights — weekly frequency, your most active days, last logged • A calendar view that shows your actual rhythm, not a wall of shame YOUR DATA NEVER LEAVES YOUR PHONE No account. No sign-up. No cloud. No analytics. No tracking. Everything lives on your device, and you can lock it behind Face ID. We can't see your data — there's nothing on our end to see. That's the entire point. BUILT FOR THE THINGS YOU'D RATHER NOT EXPLAIN - Recovery and sobriety milestones - Intimacy and relationship patterns - Mental health and mood check-ins - Medication adherence - Therapy homework and coping habits - Fitness, without the leaderboard WHY NO STREAKS? Because a streak measures compliance, not progress. Miss one day and a streak app tells you you've failed. Logbook just shows you what happened — 4 out of 7 days is still 4 days. You decide what that means. FREE, AND ACTUALLY USEFUL Track up to 3 activities free, forever. No trial countdown, no nag screens. Go Pro for unlimited activities, advanced stats, home screen widgets, and CSV export whenever you want your data out. Start logging honestly. Your patterns are already there — Logbook just helps you see them. Questions or feedback? Support@bseapps.com Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
