What is Vow?
Vow is an iPhone and iPad app, with a companion Apple Watch app, that helps adults quit habits such as smoking, vaping, alcohol, weed, porn and gambling. It builds a quit plan from your answers to a short questionnaire, anchors each quit to your own reason for quitting, tracks your streak and what you have saved, and guides you through cravings with the Craving Shield, a roughly three-minute urge-surfing session.
Which habits can I quit with Vow?
Smoking, vaping, alcohol, drugs, weed, porn, gambling, sugar, caffeine, gaming, social media, shopping, binge eating and fast food. Each habit has its own unit (for example cigarettes a day or drinks a week), its own way of counting what you gain back — money saved, money not lost, or time reclaimed — and its own set of quit methods.
Can I quit more than one habit at the same time?
Yes. Vow is built for several quits at once: each habit gets its own streak, reason, plan and savings, side by side on the Today screen. The free tier covers one habit; Premium removes the limit.
Is Vow a medical app or a treatment programme?
No. Vow is a self-help and tracking app, not a medical service, and it does not diagnose or treat any condition. For alcohol or drug withdrawal, talk to a doctor before you stop — withdrawal from some substances can be medically dangerous. Vow is designed to sit alongside professional care, not replace it.
How does Vow build my quit plan?
From your onboarding answers: the habits you choose, how much and how often, what it costs, your triggers, your toughest times and your reason. The plan is put together on your device and includes milestones from day one to one year — with day 66 marked because of habit-formation research from University College London — strategies for each trigger you named, a craving toolkit and notes for the first days. For alcohol and drugs, the plan tells you to get medical advice before stopping.
What is the Craving Shield?
A guided session for the moment an urge hits. It puts your reason in front of you, then paces your breathing through a roughly three-minute urge-surfing timer with three styles — Ride the wave, Letting go and Box breathing — shows a short coaching line and asks at the end whether the urge passed. Open it from the Today screen, the Craving Shield widget or your Apple Watch. The Craving Shield is part of Premium.
Does Vow use AI?
In one place. The Craving Shield can show a one-line coaching message written by an AI model (from OpenAI) through Vow's own server. That request contains only your habit type, the trigger you tapped, your number of clean days and the app's language — never your name, your reason, photos, voice notes or anything you typed. If the service is slow or unavailable, you see a written line instead. Your quit plan is assembled on your device.
What happens if I slip?
Log a relapse from the habit. Vow keeps your best streak, starts a fresh clean run from now and treats the slip as information about your triggers, not as failure. There is no lecture and no reset of your achievements.
Do I need to create an account?
No. Vow creates a private, anonymous identity the first time you open it, so you can start without an email or password. Signing in with Apple or Google is optional; it ties your subscription to an account you control.
Where is my quit data stored?
On your device. Your habits, reasons, photos, voice notes, check-ins, cravings and notes are stored on your iPhone and are not uploaded to Vow's servers. That also means they do not sync to a new phone by themselves — they move with your iPhone backup or device transfer.
How do I delete my data and my account?
In the app, go to Profile → Settings → Delete account & data. It deletes your sign-in account and erases your quit data from the device — habits, reasons, photos, voice notes, check-ins and achievements. It cannot be undone, and it does not cancel an App Store subscription — cancel that separately in your Apple Account settings.
Is Vow free?
Vow is free to download. The free tier lets you track one habit with its streak, money saved, daily check-in and breathing exercise, and crisis resources are always free. Premium unlocks everything else. Which features are free can change as we improve the app; the app always shows what is included before you pay.
How much does Vow Premium cost?
In the US, Vow Premium is $59.99 per year with a 7-day free trial, $12.99 per month, or $6.99 per week. Prices in other countries are set in local currency by the App Store and are shown before you buy.
Is it safe to stop drinking or using drugs on my own?
Not always. If you drink heavily or every day, or use substances such as benzodiazepines, stopping suddenly can cause withdrawal that is medically dangerous. Talk to a doctor before you stop. Vow reminds you of this in the plan for alcohol and drugs, and it is not a substitute for medical care.
