Habit tracker for iPhone

Track every habit
you have.

Most apps punish you for missing a day. Habiterr uses gentle streaks that forgive the occasional slip, and a balance chart that keeps your whole life in view.

Built for the long game.

Four ideas that make showing up feel lighter, and make the progress easier to see.

01 — Gentle streaks

Miss a day. Keep the streak.

Habits form through repetition, not perfection. Research on habit formation shows a single missed day barely dents long-term progress. What actually breaks a habit is the all-or-nothing feeling after a slip. Gentle streaks absorb roughly one miss in ten, so a bad Tuesday stays a bad Tuesday.

Why it matters
  • Motivation survives the slip that would reset other apps
  • The longer you go, the more room you earn
02 — Radar chart

Your whole life, in one shape.

Habits don’t live alone. Sleep fuels the run, the run steadies your mood, and your mood decides whether the book gets opened. The radar plots every habit’s consistency around a circle. When one side caves in you see it straight away, and can rebalance before it drags the rest down.

Why it matters
  • Neglected habits show up at a glance
  • Balance turns “am I doing okay?” into one honest number
03 — Three types of habits

Check it, count it, time it.

A habit you can’t measure honestly is one you’ll quietly drop. Not everything is yes-or-no: eight glasses of water is a count, a study session is time. When the tracker fits the habit, logging stays truthful, and small wins like “20 minutes, not zero” get the credit they deserve.

Why it matters
  • Check-ins for yes-or-no habits
  • Counters for things you repeat during the day
  • Timers with a daily goal for focused sessions
04 — Habit groups

Track the area, not just the item.

Habits stick when they serve who you want to become: a reader, a runner, someone who finishes the course. Groups bundle related habits under one area of life, with shared stats and a weekly grid. You can see how “Study” is going as a whole and spot the habit that needs a nudge.

Why it matters
  • Identity-level progress, not a to-do list
  • Group consistency, streaks and best day at a glance

The math, in plain English

How the numbers actually work.

No black box. Here’s exactly what every metric means, the formula behind it, and how to read the score.

Consistency

How often you actually show up.

consistency = completed_days / scheduled_days
  • 80–100% · excellent
  • 50–79% · good
  • < 50% · needs attention
Balance

How evenly your effort is spread.

We take the consistency of each habit, compute the standard deviation across them, then invert it into a 0–100 score.

balance = 100 × (1 − σ / σ_max)

Low spread → high balance. Six habits at 70% each will score higher than one at 100% and one at 0%.

Gentle Streaks

A streak that survives a bad week.

Every active streak comes with a small tolerance budget — 10% of its length, rounded down, minimum one. Spend a miss; keep going.

tolerance = max(1, floor(streak × 0.10))

Example: a 47-day streak allows up to 4 missed days total. You’re rewarded for the long game.

Best Streak

Milestones that mean something.

Habiterr tracks your all-time best streak per habit and surfaces it as a quiet trophy. Beat it — or rebuild without losing the memory.
