Loggr turns the things you log into clear personal patterns — and shows how they connect. Most tracking apps just count streaks. Loggr goes further: it compares everything you log against everything else, so you can see which things move together — and even how one day relates to the next. Create custom logs for anything — sleep, focus, energy, mood, weather, activities, or routines. Loggr adapts to you, not the other way around. Add an entry in seconds: open the app, tap, and you're done. Then come back to clean timelines and week, month, and year views that surface connections you would never spot on your own. What you can track: • Sleep, focus, energy, and mood • Weather, activities, and daily routines • Habits you want to build and a daily journal of what happened • Anything else — Loggr lets you create your own custom logs Why people choose Loggr: • Find connections across everything you track • See day-after relationships, not just daily counts • Custom logs that fit your life, not a fixed template • Fast, frictionless daily entries • Clear timelines and visual stats per week, month, and year • Secure cloud sync across all your devices Private by design: Loggr is a general-purpose logging tool. It does not provide advice, predictions, or recommendations — it shows patterns in the data you choose to log. Your data is private, secure, and always under your control. Start free today — create your first log in seconds and see your days more clearly. Download Loggr and discover the connections hiding in your own data.
