TriLog is The Personal Data Logger. Log what no sensor can see. Line it up with everything else. Apps and devices track your heart rate, steps, and sleep stages. They can't track how you felt at 2pm, whether focus crashed after lunch, or what symptom showed up before the weather changed. TriLog is a fast log for subjective experience — mood, energy, focus, symptoms, observations — anything only you can observe. Then it puts that on the same timeline as the rest of your life: activities, notes, weather, pollen, barometric pressure, Apple Health metrics, and more. Not scattered across apps and memory — one clock, one week on one screen, so you can see what actually lines up. Capture in seconds. Discover what predicts your best days. FREE — LOG WITHOUT LIMITS • Mood and energy throughout the day • Activities — work, sleep, exercise, leisure, anything • Sleep quality, duration, and wakefulness (Day Launch) • Meals and short observations (including calorie notes) • Health and symptom observations (freeform notes) • Journal entries and Day End reflections • Menstrual cycle notes • Habits — daily checkoffs, no streak pressure • Timeline, Metrics Grid, Charts, and note search A fast log for what you observed, when — and what else was going on at the same time. ALIGN EVERYTHING ON ONE TIMELINE Weather, pollen, air quality, UV, and barometric pressure sit alongside your entries. Apple Health metrics — sleep stages, resting heart rate, HRV, weight, steps — share the same chart and Metrics Grid. Built for correlation: did this week feel worse because of sleep, pressure, screen time, or something you logged Tuesday? THE DATA NOTHING ELSE CAPTURES Sensors capture what your body does. Mood journals capture how you felt. Neither lines them up. TriLog does both — a continuous record from the inside, on the same clock as everything else. Why do I have good days and bad days? What predicts my energy crashes? What actually improves my focus? What's behind a symptom no test has explained? These questions are unreachable by sensors and unreliable from memory. They become answerable when you have a continuous record from the inside. Built for people who already try to track energy, symptoms, or focus — and need one timeline instead of Notes, spreadsheets, and mood-only journals. DESIGNED FOR SPEED Capture has to be effortless or it won't survive a hard week. TriLog was built around that constraint. Three taps to log mood, energy, and what you're doing. No forms. No typing. No menus. Get back to your day. VISUALIZE YOUR DATA • Timeline: your entire day on one screen • Metrics Grid: weeks of energy, mood, sleep, steps, and more side by side • Habits Grid: consistency at a glance • Charts: activity breakdowns and long-term trends • TriLog Viewer: free Mac and Windows companion for years of data on one screen PRO — 30-DAY FREE TRIAL, THEN $59.99/YEAR Start with a 30-day free trial.

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/

Verdict
The clearest difference is update cadence: TriLog at every 3 weeks against Logbook's every 4 months. TriLog also leads on iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
