The habit tracker that asks less the better you do.

Most habit apps make you check a box every day, forever. Spaced Habits doesn’t. It borrows an
idea from spaced-repetition flashcards: once you’ve shown you can keep a habit, it stops
asking so often. Struggling with something? You’ll hear about it daily. Nailing it? Every week
or two. The goal is an app that quietly gets out of your way.

How it works

  • Smart check-ins. Open the app and answer at most a few quick questions. “Did you go to the
    gym today?” If it’s been a while: “How many of the last five days?” That’s it.
  • Fading questions. Consistent habits are asked about less and less, and going quiet never
    counts against you. The growing gap between check-ins is your progress.
  • Honest history. Days you answered one by one, days covered by a “how many of the last few
    days?” answer, and days the app estimated are always shown differently. No fake streaks, no
    pretending.
  • Connected habits. Protein shake after the gym? Tell the app. It won’t nag you about the
    shake on days you skipped the gym, and it tracks how well the pair actually happens together.
  • Delay, don’t fail. Can’t keep a habit this week? Delay it. Your progress is frozen, not
    lost, and it picks up where you left off.
  • Vacation mode. Pick your dates, even ahead of time, and everything pauses except the habits
    you choose to keep. The app remembers your choices for next time.
  • Answer anywhere. Home Screen and Lock Screen widgets, Apple Watch, and reply-from-
    notification, all in sync.
  • Siri and Shortcuts. “Log gym in Spaced Habits”, “Delay gym in Spaced Habits”, or “Review
    habits in Spaced Habits”. Hands-free, or wired into your own automations.
  • Reminders on your terms. A few times a day or every few days, quiet hours respected, and
    only when there’s actually something to answer.
  • Charts that mean something. Per habit: check-in interval over time and adherence trends.
    Per cluster (habits you group together): how each member is doing and how often connected
    habits happen together. Overall: a “questions per day” line that should keep going down.
  • Your data, always. Every habit and edit, every question asked, and every answer and pause is
    logged and exportable to CSV and JSON at any time.

Coming later

These are not yet in the app. Each is optional and independent.

  • Auto-complete from Apple Health. Logged a workout? The gym habit is done. No question asked.
    Deferred because it needs Health access permissions.

Ideas from Atomic Habits

Under review:

  • Habit stacking. Attach a new habit to something you already do (“after coffee, meditate”)
    and answer a whole routine in one flow.
  • Never miss twice. Two misses in a row triggers a gentle recovery mode instead of silence.
  • The two-minute version. Define a tiny fallback (“put on running shoes”) for rough weeks.
    Showing up still counts.
  • Identity votes. See each completed day as a vote for who you’re becoming, not a streak
    that can break.
  • Graduation. When a habit is truly automatic, retire it from your daily list, with an
    occasional check to make sure it’s still there.
  • Right-sizing. The app tells you when a habit has become too easy or too hard.
  • Breaking habits. Track things you’re avoiding with phrasing that makes sense.
