Ledger OS is a daily self-audit. Pick five parts of your life you want to stay honest about, answer three quick questions on each, and close the day with a clear grade - in about a minute. HOW IT WORKS 1. Pick five. Choose five audit targets from 40 across Money, Body, Mind, Relationships and Purpose: Spending, Sleep, Focus, Fitness, Gratitude, Doomscrolling, Stress, Savings and more. Or start with a ready-made set. 2. Close the day. Answer 15 short questions, three per target. Tap and keep moving. 3. Read your Report Card. Each target gets a letter grade, and so does your day. See what pulled the day down and what lifted it. 4. Watch the pattern. Trends lines up your days, weeks and two-week stretches. BUILT TO BRING YOU BACK, NOT TO SHAME YOU - Grades never fall below C-. A rough day still counts, and one bad target cannot sink the whole day. - Clean answers show progress even on hard days, and One Move names tomorrow's next step. - Changed your mind? Edit today's answers and the Report Card updates instantly. - Add quick notes to the day, before or after you check in. - A streak counter keeps your run of closed days in view, with one rest day a week. PRIVATE BY DEFAULT - Your ledger stays on your device. No account, no sign-up. - Export and import your full ledger whenever you want. - Optional AI read: only when you ask, Ledger OS sends that day's or week's summary to Anthropic's Claude using your own API key. Ledger OS is a self-reflection tool. It is not medical, financial or treatment advice.
