Curb.
Limit habits. Build streaks.
Free · Designed for iPad. Not verified for macOS.
What it does
Curb flips habit tracking on its head. Instead of building new habits, you set daily limits on the ones you want to reduce, then stay under them. Every day you succeed, your streak grows.
How it works
Pick any habit you want to cut back on. Set a daily limit. Log each time you slip. Curb handles the rest: streak tracking, smart alerts when you're close to your cap, and detailed charts showing how you're trending over time.
Key features
Set daily limits for any habit -> smoking, caffeine, snacking, doom-scrolling, you name it
Streak tracking that rewards restraint, not perfection
Bar chart visualizations for 7-day, 30-day, and 90-day windows
Smart notifications that warn you before you hit your limit
Time-bound challenges to push yourself further
100% local storage -> your data never leaves your phone
Light and dark themes
Works offline, always
Pricing
Completely free. No subscriptions, no in-app purchases, no ads. Every feature, no catch.

HABIT GUIDES
Eight guides, one for each kind of habit. Each has a step-down ladder you can follow at your own pace, swaps worth trying, and a sense of what to expect as you cut back.
LOG WHAT YOU ACTUALLY HAD
Type the number instead of tapping +1 over and over. Tap Log on any habit, or press and hold the button on your list. Setting a habit up part-way through the day? Enter what you have already had, so your first day is accurate.
LIMITS THAT FOLLOW THE CALENDAR
Weekly limits now run Monday to Sunday, and monthly limits follow the calendar month, so your allowance resets when you would expect it to. Yearly limits are new.
A CLEARER SETUP
Adding a habit now runs in the order you think in, and every field has an explanation one tap away.
WIDGET
Log more than one at a time straight from the home screen. Your remaining count and your days clean now stay correct overnight, instead of freezing until you next open the app.
FIXES
Costs typed on a keyboard that uses a comma for decimals were read incorrectly, which threw off every money saved figure. If you set a cost before this update, open the habit and enter it once more to correct it.
