PM10 Tracker

For my mother who has asthma,
We tried to make this app simple and intuitive.
This app provides national PM10 / PM2.5 / O3 pollution map in South Korea.
Since the first release in 2015, this app have been growing up based on user feedbacks.

• Minimize GPS battery usage

• Seamless Watch Complication sync
(Include Watch 4 Infographics face)

• Realtime tracking : Detect 'bad' condition and prompt user an alert

• 'Siri shortcut' for visual impairments and car drivers
(Above iOS12, WatchOS5)

In App Purchase Information

We've added in-app purchase that many users have been requesting.
Even thought some users have asked for a one-time purchase for unlimitedly service, we've prepared 'subscription type' purchase in the app since the continuous server maintenance expense.
Please understand that we are not afford to provide one time purchase for unlimited service.
Instead, we have prepared it at an affordable price so that you can use it freely.
