About

Baseline

Baseline is a discipline tracker with one organizing idea: some inputs build you, some drain you. Log both, and they resolve into a single baseline trend, a streak, and a rank you earn one held day at a time. WHAT YOU TRACK • Build: training, deep work, cold exposure, sauna, fasting windows, morning sunlight, reading • Drain: alcohol, nicotine, junk food, doomscrolling, late-night screens • Add your own inputs and set what each one is worth (Pro) HOW IT WORKS • One-tap logging: tap to log, hold to undo • Two columns, one number: build and drain resolve into a single baseline trend • Streak: consecutive days you hold your target. Miss, and it resets • Rank: a permanent ladder from Soft to Diamond, earned from total held days. It only climbs • Home screen widgets keep the number in sight PROTOCOLS Run one commitment at a time: Dopamine Reset (14 days off the scroll, late screens and junk), Dry 31, Monk Mode, Dawn Patrol, the 75-Day Challenge (few finish), or build your own rules (Pro). Miss a day, the protocol breaks. Finish, and it goes on your record. THE RECORD TALKS BACK • The Debrief: a monthly after-action report. Days held, best streak, rank at close, what anchored you. Shareable • Deep reads (Pro): the drain behind your missed days, your week against your month, how one miss becomes two • The grid: every day as a square. Tap any day for its full breakdown • The guard nudge (Pro): warned before your statistically weak day BUILT DIFFERENT Most habit apps hand out confetti. Baseline keeps a ledger: two columns, one baseline, framed for discipline, not celebration. MADE FOR • Those rebuilding after cutting alcohol, nicotine, screens, or other cheap inputs • Anyone trading easy wins for earned discipline • People who want one number to move, not a spreadsheet PRIVATE BY DESIGN • No account, no login, no cloud: everything stays on your device • Works fully offline. Export your data anytime PRICING • Free: the full core loop. Log, streak, rank, protocols, the monthly Debrief • Pro, a one-time Lifetime purchase: deep reads, the guard nudge, build-your-own protocols, custom weights and inputs, full trend history, themes • Restore purchases anytime, no account required You quit the cheap dopamine. Now earn the hard kind. Payment will be charged to your Apple Account at confirmation of purchase. Baseline Pro Lifetime is a one-time purchase, not a subscription. Subscriptions bought earlier renew automatically unless canceled at least 24 hours before the end of the current period; manage or cancel them in your Account Settings.
