Asthma support. Know what sets it off.
Track your peak flow, your symptoms, your rescue-inhaler use, and the triggers behind your flares — together, in one place. Leo surfaces the patterns so you and your care team can see what's driving your breathing, on device.
Log what you feel, the moment it happens.
Wheezing, shortness of breath, coughing, chest tightness — and the chest pain or discomfort that can come with a bad flare. Log a single symptom or a full flare-up in seconds, with how intense it was.
No food, calorie, or weight tracking, and no photos — just the breathing symptoms that matter, captured fast so you're not fighting the app mid-flare.
Your numbers, against your personal best.
Log peak flow (PEFR) readings from your meter — morning, evening, or anytime — and Leo tracks them against your personal best, showing whether each one lands in your green, yellow, or red zone, with a trend over time.
Add your rescue inhaler as an as-needed medication and log each use with one tap. Rising rescue use, one of the earliest signs that control is slipping, stands out before it becomes a crisis.
Peak flow zones
Readings tracked against your personal best — green / yellow / red, with a trend line.
One-tap rescue log
Log albuterol or your rescue inhaler as you use it — Leo tracks how often and when.
Oxygen & breathing
Track SpO₂ and respiratory rate in Vitals, including readings from a connected device.
See what's behind your flares.
Tag what preceded a flare — exercise, cold air, allergens, smoke, an infection, strong smells, or stress. Over time Leo's on-device pattern detection can show which triggers and activities line up with your worst breathing days.
It's descriptive, never a prediction or a diagnosis — just your own patterns, plainly stated, so you can act on them.
Trigger tagging
Allergens, cold air, smoke, weather, infection — tag the trigger with each flare.
Activity & exertion
Note exercise and exertion — exercise-induced symptoms are a common asthma pattern.
Patterns, on device
When the data clears a strict statistical bar, Leo surfaces the co-occurrences — never a guess.
What ships in the Asthma hub.
Leo tracks. It doesn't diagnose.
Leo doesn't diagnose asthma and has no screener or score. It's descriptive — your patterns, no judgment.
A severe attack is a medical emergency: if you're struggling to breathe, get help right away. This hub is for tracking between those moments, and for sharing with your care team.
Know what sets it off.
Symptoms, rescue-inhaler use, and triggers — tracked together on device, so you and your care team can see your asthma's rhythm.
