Health Information

Not a medical service
Nefira is not a medical device. It does not diagnose, recommend treatment or determine medication or dosage, and it does not replace a doctor or other health professional. Consult an appropriate health professional alongside using the app and before making health decisions.
General timelines
Health Journey and health milestones show general timelines based on the cited sources. Individual change varies with past smoking, overall health and other factors. Completing a target does not mean the health outcome has been measured or confirmed in your body. Sources and the shared explanatory note are available in each target’s details.
Percentages and illustrations
Progress percentages for health targets describe progress through the relevant time interval, not a personal medical recovery rate. The 365-day Lung Journey and the valley are time-based visual journey indicators. The lung illustration is not a scan and does not measure your lung capacity, disease risk or recovery.
Support activities
The breathing focus, short attention activities and motivational messages provide general support. They are not therapy or an emergency service. Stop an activity if it causes discomfort. Seek a health professional’s advice when you need personal assessment of symptoms, treatment or a method for quitting smoking.
Emergencies
If you believe you have a serious or urgent health problem, seek appropriate emergency medical care. Nefira does not send an emergency call, monitor your condition, summon help or provide a live health service to wait for.
