Disciplines is the productivity system for people who are serious about getting things done. Most apps track one thing. Disciplines connects your tasks, habits, goals, focus sessions and analytics so nothing falls through the cracks. FOCUS SESSIONS & APP BLOCKER Start a focus session and Disciplines blocks distracting apps the moment it begins. Use it for deep work, a sleep routine or a wind down session. Difficulty modes (Normal, Timeout, Deep Focus) control how strictly you can quit early. TASK & HABIT TIMER Time any task or habit while blocking distractions at the same time. Track exactly where your hours go on the Lock Screen, Dynamic Island, Home Screen widgets and Apple Watch. APP LIMITS Set a daily time budget or open hours for the apps that steal your attention. Choose Easy limits you can adjust anytime, or Strict limits that stay locked until the window opens or the budget resets. HABIT TRACKER Track daily habits with streaks, completion rates and weekly progress. Every check in compounds. Every streak builds momentum. GOAL PLANNER Break big goals into tasks, assign deadlines and watch your progress with built in charts. Goals aren't just saved, they're worked on every day. PRODUCTIVITY SCORE & ANALYTICS Your daily score is built from four factors: time management, accuracy, efficiency and consistency. No vanity metrics, just an honest read on how locked in you actually were. Disciplines is for the person who doesn't need motivation. They need a system.
