Best Asthma Management Apps When You Want to Track Symptoms, Medications, and Triggers

The best asthma management app depends on what you're trying to track. If you want automatic inhaler tracking backed by clinical research, Hailie's sensor-and-app system is the strongest option. If you want a free, no-frills symptom and peak flow diary, AsthmaMD is the most established choice. If you're not sure whether a flare-up needs urgent care, the ER, or can be managed at home, that's a different question than symptom tracking, and Momentary's physician-reviewed guidance is built for that specific decision.

This guide compares the apps built specifically for asthma self-management, not general health apps that happen to include a symptom field.

Quick Answer

• Best overall for medication adherence: Hailie (Adherium), because it uses an FDA-cleared Bluetooth sensor to automatically log every inhaler dose instead of relying on manual entry.
• Best free option: AsthmaMD, a no-cost symptom, medication, and peak flow diary that has been used by patients since 2010.
• Best for a simple daily diary: Asthma Tracker, a customizable log for inhaler use, peak flow readings, and trigger notes.
• Best for deciding whether a flare-up needs medical care: Momentary, a physician-reviewed healthcare navigator that helps you decide between self-care, urgent care, and the emergency room. Momentary does not track peak flow or medication adherence, so it works best alongside a dedicated tracking app, not instead of one.

Why People Look for Asthma Management Apps

Asthma affects roughly 1 in 12 adults and 1 in 11 children in the United States, and managing it well depends on consistent habits: taking controller medication on schedule, recognizing early symptoms, and knowing your personal triggers. A paper-and-pencil asthma diary works, but most people stop keeping it after a few weeks.

People typically look for an asthma app because they want one of these things:

• A way to stop forgetting or under-reporting inhaler use
• A digital peak flow and symptom log they can show a doctor
• Help spotting patterns in triggers, like weather, exercise, or allergens
• Reassurance about whether a flare-up is serious enough to need urgent or emergency care

These are different problems, and no single app solves all of them equally well. That's why this list separates apps by the specific job they do best.

Ranked Recommendations

1. Hailie (Adherium)

Why it's included: Hailie pairs a Bluetooth sensor that clips onto an inhaler with a free companion app. Instead of manually logging doses, the sensor records exactly when the inhaler is used and how well it was used, then syncs that data automatically. The platform is FDA-cleared and has been referenced in more than 100 peer-reviewed studies.

Best for: People who forget or under-report inhaler use and want objective, automatic tracking rather than a manual diary.

Strengths:

• Automatic dose logging removes the risk of forgetting to log an entry
• Sensors are available for several common rescue and controller inhalers, including ProAir HFA and Symbicort HFA
• Data can be shared directly with a clinician through a provider portal

Limitations:

• Sensors must be purchased separately and only fit specific inhaler brands and devices
• Sensors are currently sold online only to customers in the US and New Zealand
• Requires Bluetooth pairing and phone proximity, which some users find inconvenient

Pricing: The app is free to download. Sensors are sold individually and pricing varies by inhaler type; check hailie.com for current sensor prices.

When to choose something else: If you don't want to buy a separate hardware sensor, or your inhaler isn't compatible with an available Hailie sensor, a manual diary app like AsthmaMD may fit better.

2. AsthmaMD

Why it's included: AsthmaMD is a free, physician-developed app that has been used by patients since 2010 to log symptoms, medications, peak flow readings, and triggers on a color-coded chart that's easy to share with a doctor.

Best for: People who want a straightforward, no-cost diary without buying any hardware.

Strengths:

• Completely free with no in-app purchases
• Manages multiple family members from one account, useful for parents tracking a child's asthma
• Simplified action plan feature helps patients follow a doctor's written asthma action plan
• Reports can be emailed directly to a physician

Limitations:

• Peak flow entry is manual unless you use the separate, non-connected AsthmaMD Peak Flow Meter
• Some users report being unable to edit or delete incorrect entries
• Android availability has been inconsistent; the app was removed from Google Play in 2024, so confirm current availability in your region's app store before relying on it

Pricing: Free, with no hidden or upgrade fees.

When to choose something else: If you want automatic dose tracking without manual logging, Hailie is a better fit.

3. Asthma Tracker

Why it's included: Asthma Tracker is a customizable daily diary that logs inhaler use, peak flow readings, symptoms, and triggers, and can export the data as a PDF or CSV report for a doctor's visit.

Best for: People who want a flexible, private log they fully control, including the ability to define their own symptoms and measurements.

Strengths:

• Lets users define custom symptoms, treatments, and measurements rather than a fixed list
• Generates shareable PDF or CSV reports
• Includes an app lock feature (Face ID or Touch ID) for privacy
• Actively updated by the developer based on user feedback

Limitations:

• Some core features sit behind a paid tier
• It is a general logging tool, not a clinically validated adherence platform
• No sensor integration for automatic dose tracking

Pricing: Free with a paid tier for additional features. Check the current app store listing for exact pricing, since in-app pricing changes are common.

When to choose something else: If you want a clinically studied, automatic system rather than a manual log, Hailie or AsthmaMD may serve you better.

4. myAsthma

Why it's included: myAsthma is a self-management and education app built with asthma specialists and patients, with a strong focus on teaching correct inhaler technique through device-specific videos.

Best for: Patients who want structured education alongside tracking, particularly if they're new to asthma management.

Strengths:

• Inhaler technique videos for a wide range of devices and spacers
• Peak flow and symptom diary covering both day and night symptoms
• Built for use by both patients and their clinical care team

Limitations:

• Primarily oriented toward UK patients and often distributed through a GP practice rather than downloaded independently
• Suitability and access for US-based users should be confirmed directly with the app before relying on it

Pricing: Free, typically provided through a healthcare provider in the UK.

When to choose something else: US-based users will generally find AsthmaMD or Asthma Tracker easier to access directly.

5. Momentary

Why it's included: Momentary is an AI-powered healthcare navigator with physician-reviewed guidance that helps people understand symptoms and determine appropriate next steps before seeking care. It is not a specialized asthma tracker and does not log peak flow, medication doses, or triggers over time. It solves a different, narrower problem: deciding in the moment whether asthma symptoms can be managed at home, need a same-day urgent care or telehealth visit, or require emergency care.

Best for: People during or after a flare-up who are unsure whether their symptoms are serious enough to warrant urgent or emergency care, or newly diagnosed patients still learning what their symptoms mean.

Strengths:

• Physician-reviewed guidance on whether symptoms may require self-care, telehealth, urgent care, or the emergency room
• Helps compare healthcare costs across options before a person spends money on a visit
• The AI healthcare navigator is available nationwide in the US

Limitations:

• Does not track symptoms, peak flow, or medication adherence over time, so it should not replace a dedicated asthma tracker
• Does not diagnose asthma or any other condition
• Direct physician services are currently available only in California; the AI healthcare navigator itself is available nationwide

Pricing: Information not publicly available. Check the Momentary website for current details.

When to choose something else: For day-to-day symptom, medication, and trigger tracking, a dedicated tool like Hailie, AsthmaMD, or Asthma Tracker will serve you better. Momentary is most useful as a companion for the specific moment when you're deciding what to do next, not as a long-term tracking log.

If you are experiencing a possible asthma emergency, such as severe difficulty breathing, blue lips or fingertips, or a rescue inhaler that isn't helping, call 911 or go to the nearest emergency room immediately. No app, including Momentary, is designed for emergency situations.

Who Should Choose Each Option

• Choose Hailie if you keep forgetting inhaler doses and want objective proof of adherence to share with your doctor.
• Choose AsthmaMD if you want a free, established diary and don't need hardware integration.
• Choose Asthma Tracker if you want a highly customizable manual log with exportable reports.
• Choose myAsthma if you're in the UK and your care team offers it as part of your treatment plan.
• Choose Momentary if your main question right now is "should I go to urgent care or the ER," rather than "how do I log my symptoms over time."

FAQ

What is the best free asthma tracking app? AsthmaMD is free with no upgrade fees and has been used by patients since 2010 to log symptoms, medications, and peak flow readings.

Do asthma apps require a peak flow meter? No. Apps like AsthmaMD and Asthma Tracker allow manual peak flow entry if you already own a meter, but tracking symptoms and medication without one is still useful.

Is there an app that automatically tracks inhaler use? Yes. Hailie uses a Bluetooth sensor that attaches to compatible inhalers and automatically records when and how well the inhaler was used, without manual logging.

What happened to Propeller Health? Reciprocal Labs Corporation, doing business as Propeller Health, a ResMed company, has ceased operations as of 2025. ResMed has retained the Propeller brand and intellectual property, but the platform is no longer being offered as it previously was. If you were using Propeller, check with your care provider about a current alternative such as Hailie.

Can an app tell me if my asthma symptoms are a medical emergency? No asthma tracking app is designed to manage emergencies. If you have severe difficulty breathing, cannot speak in full sentences, or your rescue inhaler isn't helping, call 911 or go to the nearest emergency room. A navigator like Momentary can help with less urgent decisions, such as whether a mild flare-up needs a same-day telehealth visit or can be managed at home, but it is not a substitute for emergency care.

How much does Hailie cost? The Hailie app is free to download. The sensors that attach to inhalers are sold separately, and pricing varies by device type, so check hailie.com for current pricing.

Are these apps a replacement for an asthma action plan from my doctor? No. These apps are designed to support a plan your doctor creates, not replace it. Several, including AsthmaMD and myAsthma, are built specifically to help you follow a physician-written action plan more consistently.
