Asthma Tracker 3 supports you in keeping your asthma diary up-to-date by making it easy to track your peak flow values, your asthma medication intake and your asthma related symptoms. In addition, you can add contextual information to each entry by either associating it with a pre-defined event (such as a doctor’s appointment) or with individual notes.

With the built-in reminder, you can set Asthma Tracker to remind you to take your daily base medication, to measure your peak flow and to record your symptoms. At the end of each month, it will also prompt you to complete the widely-known Asthma Control Test™ whose intent is to give you a rough idea as to how well controlled your asthma is.

The aggregated information in Asthma Tracker's chronological overview leverages the Health app to let you quickly asses how your asthma is progressing. Asthma Tracker stores and displays peak flow values stored in the Health app as well as puffs and symptoms alongside your daily step count. This way you can easily see how your daily activity influences your asthma and related symptoms.

Select individual days to get a more detailed view of each entry (peak flow, puffs or symptoms) on that particular day as well as the recorded step counts on that day.

Share your recorded asthma entries with your doctor during an appointment or take an in-depth look at it yourself on your desktop or other device with a bigger screen using the built-in integration with datalinker.io, our fully end-to-end encrypted solution for secure data transmission. Just visit web.datalinker.io, scan the QR code with Asthma Tracker and your entries are encrypted on your iPhone and copied securely to datalinker for temporal storage. From there you can show it to your doctor, print or save it to PDF.

Best Asthma Tracking App

This is the best Asthma tracker I have found in the App Store. It has the best looking interface and is very simple and easy to use. Data (peak flow, inhaler usage, and symptoms) can easily and quickly be entered.

My two requests... the app does pass peak flow data into the Apple Health App but does not pass inhaler usage. I can't decide if I want to continue using the application for this reason so please add the feature.

Secondly, I would like to see a widget for rapid entry of data, particularly inhaler usage. Symptoms would be a plus to. It would also be nice to have an AppleWatch app for adding data although that would be my least priority and not a big deal.

We just released version 3.0 than imports inhaler usage to Health. Plus, you can now use 3D Touch to quickly add peak flows, inhaler usage, symptoms and notes.

Good app, would like to see more

I like this asthma tracker because is simple/easy to use and you do not need to create an account. I would like to see the ability to have multiple entries per day and the option to add pulse/ox.

Developer Response ,

You can add multiple peak flows, puffs and notes for each day. Simply tap on a day to see an overview of all entries of that day.

Good to start but crashing constantly

This app was really great when I first downloaded it (less than 1 month ago), but now it’s crashing every time I try to log any information. Not helpful.

Developer Response ,

Hi, sorry to hear this. We had some trouble isolating the issue but it is fixed now. The update will roll out to all customers in the coming days.
