Curb the urge.
Keep the streak.
A recovery companion for whatever has a hold on you — porn, alcohol, smoking, vaping, weed, social media, gambling. One app, one streak per habit, and a toolkit for the moment it actually gets hard.
Built for the hard moment, not the easy one.
Most trackers count days. Curb is designed around the two minutes when a craving peaks — and around what happens after a slip.
The urge toolkit
Box breathing, a two-minute delay timer, your own written reasons, and a distraction game — in sequence, one tap from the home screen.
A streak per habit
Quitting more than one thing? Each habit has its own counter. Slipping on one doesn't erase the others.
Slips without shame
Log what happened, name the trigger, pick three next actions. Your total clean days never reset — and you can undo a slip for 24 hours.
Progress you can read
A month calendar, a 90-day grid, longest streak, urges survived, and how your mood tracks against it all.
Your reasons, in your words
Written when you're clear-headed, shown back to you when you're not.
Milestones worth reaching
Ten tiers from Spark to Free. A slip restarts the climb — never the map.
Why Curb is different
Your recovery data never leaves your phone.
What you're quitting, every slip, every mood check-in, every journal note — all of it is stored in a database on your device and nowhere else.
- No account. Nothing to sign up for, no email, no password.
- No servers. Your entries are never uploaded, because there's nowhere to upload them to.
- No analytics, no ads, no trackers. Not a single third-party tracking SDK.
- No selling or sharing. Ever — and we have nothing to sell.
- Export or erase anytime. Take your data as a file, or wipe it from Settings.
Full detail — including the few things that do use the network, like purchases and app updates — is in the privacy policy.
Curb is a self-tracking tool, not treatment.
Curb is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. It is not a substitute for professional medical advice, diagnosis, or treatment.
Stopping some substances abruptly — alcohol and benzodiazepines in particular — can be medically dangerous. Talk to a qualified healthcare professional before you change how you use them.
