How It Works
Built to replace opening separate weather, air quality, and calendar apps every morning. Public data feeds refresh automatically every 3 hours with official source attributions (KMA, AirKorea, KASI, KTO) displayed on screen.
Where to Access
Search for '오늘 한 장' inside the Toss app to open it immediately—no separate installation or sign-up required.
Frequently Asked Questions
Does the app track my GPS location?
No. You simply pick a region from a list, and your selection stays on your device without storing location history on any server.
Why do fine dust numbers differ slightly from other apps?
Real-time AirKorea station readings can vary slightly depending on the nearest monitoring station and refresh interval.
