A little clarity.
Before you begin.

01 / THE CREATOR

Made by someone
who knows the struggle.

iQ is created and maintained by Oleg Plugaru, an independent developer.

I started building iQ after my day job, drawing on my own experience of trying to quit. I wanted a simple way to see my progress and have something to turn to when a craving arrived.

02 / YOUR INFORMATION

Know what stays with you.

No account is needed to use iQ. Your quit profile, goals, craving notes and activity history are stored on your device. Widgets and a paired Apple Watch receive limited progress information. Device backups may also contain app data, depending on your Apple settings.

Purchases and measurement

Apple handles payments. RevenueCat processes subscription records, a randomly generated app identifier, technical information and Apple Ads attribution to manage Premium and measure campaign performance. iQ does not send your quit profile, craving notes or goal photos to RevenueCat.

iQ does not display third-party advertisements or sell your personal information. This website uses Cloudflare Web Analytics; Cloudflare may also retain operational request logs.

Deleting your information

Deleting the app removes its local data from that device; offloading it keeps the data. Apple-managed backups and data on a paired Watch may remain separately. Starting a new quit attempt does not erase all saved data.

For requests about subscription or attribution data, contact [email protected]. Those records are separate from local app data. Deleting the app or requesting data deletion does not cancel a subscription.

03 / HEALTH SOURCES & EVIDENCE

Understand the estimates.

iQ is a self-management tool. Its recovery timeline draws on the public sources below. Milestones describe general patterns after quitting smoking; they do not measure your health or predict your individual recovery.

• NHS Better Health: Quit smoking ↗

  Information on quitting and common recovery milestones.

• CDC: Benefits of Quitting Smoking ↗

  Health benefits and changes in risk over time.

The timer uses your saved quit date. Cigarettes skipped and money saved are estimates based on the habits and prices you enter.

For personal treatment advice or help choosing cessation medication, speak with a qualified healthcare professional. You can also use the NHS guide to quitting support; service availability depends on your country.

04 / ACCESSIBILITY

Support for the way you use your iPhone.

For iQ 1.4.2 on iPhone, the published App Store accessibility information lists:

• VoiceOver
• Larger Text
• Dark Interface
• Sufficient Contrast
• Reduced Motion
• Differentiate Without Color Alone

These are developer-declared features for the iPhone app. Support can differ on iPad and Apple Watch. See the App Store listing for current platform details.

If something is difficult to read, hear or operate, tell me what got in your way.

05 / FREE & PREMIUM

Choose what works for you.

Free

Your smoke-free timer, SOS activities, recovery timeline, core achievement badges, daily missions and one active savings goal.

Optional Premium

More active goals, full craving history, longer-term insights, weekly reflections and additional progress views.

Available purchase options, local prices and billing terms are shown in the app before you buy. Subscriptions renew unless cancelled. A lifetime purchase, where offered, is a one-time payment.

Manage or cancel a subscription in your Apple subscription settings. To recover an existing purchase, use Restore Purchases in iQ’s Premium settings with the Apple Account used to buy it.

06 / HELP & CONTACT

There’s a person here.

For app questions, a bug, an accessibility issue or a privacy request, contact Oleg at [email protected].

For a technical issue, include the app version, device model and what happened. Share only the details needed to explain the issue; you can leave out personal craving notes and other health information.

You can also visit the support page. Support email is for help with iQ and is not a clinical advice service.
