The one-tap tracker for anything in your life. Mood, meals, migraines, workouts, medication, sleep — you decide what to keep an eye on, and logging it takes a second. Over time, Log Simply shows you how it all connects. TRACK ANYTHING. ONE TAP. Most trackers do one thing: mood, or habits, or workouts. Log Simply does whichever ones you need. ⎷ Build your own tiles — from scratch or from curated templates ⎷ Tap a tile to log; the entry is timestamped and done ⎷ Add details only when you want them — duration (with timer), a 1–5 rating, a count or a note ⎷ Around 1,600 icons and a full color palette; drag to reorder, long-press to edit ⎷ Exclusive categories for things with one value per day, like mood or sleep quality ⎷ Optional reminders with device notifications WHAT PEOPLE TRACK ⎷ Health — migraines, food sensitivities, skin, pain, cycle, medication ⎷ Mind — mood, energy, sleep, stress ⎷ Body — workouts, recovery, injuries ⎷ Life — habits, routines, recurring events, things worth remembering CALM AND PRIVATE ⎷ No streaks, no goals, no gamification — no pressure to "keep it going", no shame for missed days ⎷ No ads, nothing to upsell — free today, and accounts created free stay free ⎷ Stored anonymously in a secured database in Switzerland; no name or email travels with your logs ⎷ Only you have access; insights are computed on your device, never on a server ⎷ Export everything to XLSX, CSV or JSON any time; backup and restore with one tap ⎷ Deleting your account is as easy as creating it WHERE IT SHINES: SEE HOW IT CONNECTS A pure logger keeps the record.
