How to choose an asthma tracking app

The essentials to check first

A few basics are worth checking before you pick an asthma tracking app:

• Are the day-to-day tracking features free, or hidden behind a paywall?
• Is your health data hosted on infrastructure certified for health data (in France, that's the HDS certification)?
• Was the app designed with a pulmonologist or asthma specialist, rather than adapted from a generic habit-tracker template?
• Does it work for both adults and children, and for all types of asthma?

A clinically validated way to check your control

Not all apps measure asthma control the same way. Look for one that uses a recognized, validated tool rather than a made-up scoring system.

• The Asthma Control Test (ACT) is a standardized 5-question questionnaire used by respiratory specialists
• A score below 20 out of 25 is worth discussing with your doctor

Evoco includes the ACT and keeps a history of your scores over time, so you can see whether your control is improving or slipping.

Reports that actually help at your appointment

A tracking app is only useful if what it collects can reach your doctor. Some apps just show you graphs — look for one that turns your data into something you can bring to a consultation. Evoco automatically generates a monthly PDF report — symptoms, treatments, peak flow, ACT scores, and environmental correlations — designed to be handed directly to your pulmonologist or GP.

Understanding your triggers, not just your symptoms

Asthma often reacts to things outside your control, like pollen or air pollution. An app that only logs symptoms misses half the picture.

• Pollen levels (grasses, birch, ragweed…) and air pollution (PM2.5, ozone)
• Weather conditions and physical effort

Evoco correlates your symptoms with this environmental data automatically, and can alert you when conditions worsen in your area.

Why these criteria matter

• They protect your health data
• They make sure the tool is actually built for asthma, not adapted from a generic app
• They save time at your medical appointments
