FAQ about Chronic Illness management using Best Life by LLIF
Why am I asked to enable Location services?
The temperature, barometric pressure, humidity, and other factors definitely have an impact on your day to day.
Enabling location services lets your diary capture those daily differences.
Do I need to enable Health services, too?
Optional only! However, by syncing the Health data that your Apple Health kit or Google Fit already captured, you can see even more trends in your own data.
How do I see my Events on a graph?
Once in your Diary, go ahead and tap the bottom menu icon for the little person on their data! Scroll to the Event count graph and tap into it.
In the top-right of each graph you will find the search and filter icon that opens a drawer with the ability to add specific Events on top of the data you’re reviewing.
What pollen types are included?
Right now, we have OpenAQ and Ambee providing our pollen information. This will include pollen from ragweed, tree, and grasses.
What elements are included for air quality?
Right now, we have air quality data sourced from OpenAQ. This includes Ozone, Nitrogen Dioxide, Carbon Monoxide, and Carbon Dioxide.
For the ease of review, we separate the elements into their own graphs in Best Life Health Diary.
How do I get more data providers connected?
