Sniff It brings together three things: structured smell training to retrain your nose, mindful smell awareness to reconnect with everyday scents, and a smell journal to capture them. With Sniffy the snail to keep you going.

The app is fully functional and available for free via TestFlight while I finalize it for the App Store. Your feedback determines what's fixed and added next - I read every message.
Millions of people live with a reduced or absent sense of smell, often after a viral infection like COVID-19. It rarely makes headlines, but it can quietly change how food tastes, how safe you feel, and how connected you are to places and memories.
The encouraging part: smell can be trained. Just a few mindful minutes a day, smelling a small set of familiar scents, is a clinically recognised way to support recovery, and Sniff It makes that routine easy to keep up.
Sniff It pairs the proven training method with two everyday practices, so smell becomes a real part of your day, not just an exercise.
Run short, structured sessions with your own set of familiar scents to retrain your nose. This is the clinically recognised method for supporting smell recovery, made into a habit you can keep.
Guided breathing and mindful smelling help you slow down and tune back into the scents around you, from your morning coffee to rain on the pavement. Calming, grounding, and good for anyone.
Capture the smells you notice with a title, notes, tags, and an optional photo or place. Over time your journal becomes a personal map of the scents in your life and how your sense of smell is changing.
Built around one clear purpose, with just enough delight to keep you coming back.
Choose your scent set, run timed sessions, and rate each scent 0-10. The proven, structured routine at the core of smell recovery.

Smell training only works if you keep going. So Sniff It borrows the best of habit apps: small daily goals, visible streaks, and a companion you genuinely want to look after.
Sniff It has no analytics, no ads, and no account. Everything you log lives on your device and syncs only through your own private iCloud via Apple CloudKit. Neither I nor any third party can see it.

Nothing for me. Sniff It does not transmit your data to any server of mine and contains no advertising or analytics frameworks. Your entries - training logs, diary notes, mindfulness sessions, gamification progress, and settings - are stored on your device and synced to your personal iCloud account via Apple's CloudKit.
Sync runs through your personal iCloud account (Apple Inc., One Apple Park Way, Cupertino, CA 95014, USA). I have no access to it at any time. See Apple's Privacy Policy.
Sniff It does not collect personal data from anyone, including children under 16.

Yes. The full training routine is ad-free and usable without any purchase. Optional one-time Pro and Supporter upgrades add personalisation and help fund development - or buy me a coffee on Ko-Fi.
Olfactory training is a clinically recognised approach to support recovery from smell loss. Results vary and take time - Sniff It helps you stay consistent, but it isn't a medical device or a substitute for professional advice.
