Habit Batcher is a clean, focused habit-tracking app built around a proven behavioral principle: habit stacking. Habit stacking is a well-researched concept in behavioral science showing that habits are more likely to stick when they’re grouped into routines and anchored to existing behaviors—rather than tracked in isolation. Habit Batcher applies this science by letting you batch habits into structured routines, helping you reduce friction, build momentum, and stay consistent over time. Instead of managing dozens of separate habits, Habit Batcher lets you group habits into meaningful batches like Morning, Evening, or Health. You complete habits as a single routine, and streaks are tracked based on full routine completion—mirroring how habits actually form in real life, as sequences rather than silos. Track your progress visually with monthly and yearly streak calendars, current and longest streaks, and total completed days across the year. For high-effort days that aren’t perfect, optional partial-progress days let you recognize consistency without breaking momentum. Not everything should affect your habits. Habit Batcher includes a separate daily to-do list for tasks that don’t belong in streaks. To-dos can have one-time reminders, automatically surface when incomplete, and never break your habit streaks. Home screen widgets keep routines visible and actionable. Widgets can show your batches and habits, an optional daily calendar, and an optional to-do list—designed to reduce friction and increase follow-through without opening the app. Habit Batcher offers deep customization while staying clean and intentional. Choose light, dark, or system themes, customize backgrounds with gradients or photos, adjust accent colors, card styles, progress bars, calendar styles, streak colors, and haptics. Everything is designed to support long-term consistency, not visual noise. Smart notifications help you stay on track without becoming overwhelming. Set daily reminders, enable per-batch reminders, and use flexible scheduling that fits your routine rather than interrupting it. Premium features include habit and batch templates for fast setup, advanced customization options, partial progress tracking, per-batch reminders, and reliable backup and restore. Automatic daily backups, manual backups, and restore options ensure your data is always protected. Getting started is easy. A guided onboarding experience helps you set up your first batches, or you can skip it and start immediately. Starter batches are included, and search makes it easy to find habits or routines as your system grows. Habit stacking works. Habit Batcher makes it usable. Build routines, track progress, and stay consistent—one batch at a time. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
