# Unvay: a quit smoking and vaping app with on-device data, built and run by ODEL

> How ODEL built Unvay, a quit smoking and vaping app for iPhone and Android with a personal quit plan, craving tools, logging and widgets, with no account and data kept on the device.

Unvay is a quit smoking and vaping app for adults, designed, built and published by ODEL on iPhone and Android. Users create a personal quit plan for cigarettes, e-cigarettes or other nicotine products, pick a small action from guided craving rescue tools when an urge hits, and log urges, mood and triggers next to a visual streak and progress tracking. There is no account: the plan, journal and craving entries stay on the device and are not sent to ODEL DEV LLC or an analytics service. It is built with Expo and React Native, with iOS and Android widgets, notifications and a subscription with a 3-day trial for eligible users. It shows how ODEL handles a sensitive wellness app without medical claims or data collection.

## The problem

Adults trying to stop smoking or vaping need help in the moment a craving hits, and a plan they can follow. Many quit apps cover cigarettes only. Unvay covers cigarettes, e-cigarettes and other nicotine products in one plan.

## What ODEL built

- Personal quit plan that can be edited later
- Guided craving rescue tools
- Urge, mood and trigger logging
- Visual streak and progress tracking
- No account, data kept on the device
- Home Screen shortcuts
- Subscription with a 3-day trial for eligible users

## Technology

- **App**: Expo SDK 55, React Native 0.83 and React Navigation
- **Data**: On the device, no backend and no analytics
- **Widgets**: react-native-widget-extension (iOS) and react-native-android-widget
- **Purchases**: expo-iap
- **Native features**: expo-notifications, expo-quick-actions, expo-video

## Launch and growth

- Live on the App Store (iOS 15.1 or later) and Google Play
- Store listing in English
- Version 1.1.0 released 2026-10-05: renamed from VapeLess to Unvay with a new design and icon, cigarette and e-cigarette plans and clearer subscription details
- Free download with Unvay Plus Monthly and Yearly subscriptions

## What we learned

- For sensitive habits, no account and no analytics is a feature people can read on the store page, and it keeps privacy labels short. Ask whether your app needs a server at all before paying for one.
- A rename and a wider scope (from vaping to all nicotine products) can ship as an update to the same app instead of a new listing.
- Health-adjacent apps need careful wording: Unvay supports a quit attempt and makes no medical claims.
