The Lion App StudioSmall apps.
Lion-sized habits.
We design and build focused mobile apps for iOS and Android that help people track and change everyday habits – simple to use, private by default.

Our first app helps adults who want to cut down on and quit e-cigarettes. Track every puff, see how much nicotine you actually use and follow a gradual plan to a quit date you choose.
- Puff and nicotine (mg) counter
- Personal plan with a quit date and decreasing daily limits
- Daily, weekly and monthly statistics
- Your consumption data stays on your device
For adults (18+) only. The app is a self-tracking tool, not a medical device, and does not provide medical advice.
