Build good habits, quit bad ones, and cut back without forcing every goal into a checkbox. Abys is a habit and streak tracker with flexible goals, interactive widgets, Apple Health auto-logging, and an ocean-inspired Depth Ladder that turns consistency into visible progress. BUILD, QUIT, OR CUT BACK Track habits your way: • Simple yes/no habits • Quantities like glasses of water or pages read • Timed habits • Abstinence day-counters for quitting • "Stay under X" targets for cutting back gradually GO DEEPER WITH EVERY STREAK Your streak becomes a journey through five ocean depths: Sunlight, Twilight, Midnight, the Abyss, and the Trench. Each zone has its own look, turning days of practice into visible progress. TRACK WHEREVER YOU ARE Log habits from Home Screen and Lock Screen widgets, Control Center, Siri Shortcuts, or the standalone Apple Watch app with complications. Follow guided multi-step routines with Live Activities. LET APPLE HEALTH DO THE LOGGING Link a habit to steps, active energy, heart rate variability, or sleep to log progress automatically from Apple Health. A manual check-in always takes precedence. EDIT YOUR PLAN, KEEP YOUR HISTORY Change a habit's schedule, start date, or weekdays without deleting and recreating it. Review your history and see statistics calculated from your recorded activity. TRACK TOGETHER Turn a habit into a shared group goal, or track your own copies with streaks shown side-by-side. ACCOUNT AND DATA Only a small progress summary (your current streak and a completion count, not your raw log) is shared with the group. Sign in with Apple is optional and only needed for cloud sync, groups, and restoring a purchase across devices — core local habit tracking never requires an account. Health data never leaves your device except through your own Apple Health / iCloud account — it is never sent to Abys's servers. FREE TO START Track up to 5 habits and 1 group. Full history, export, and widgets are included. Abys Pro unlocks unlimited habits and groups, Apple Health auto-logging, iCloud sync and backup, the Apple Watch app, and Depth Zone themes. Abys brings together "abhyas" (disciplined practice) and "abyss" (depth): daily practice toward a depth you keep discovering. Your practice. Your depth. Abys.
