Smooth
Turbulence for your flight, counted down in the air - even in airplane mode.
Add a flight and Smooth reads the official aviation turbulence forecast along your route: a bump bar from takeoff to landing, taller where it's rougher, with plain captions like "bumpy for about 35 minutes over the mountains". Official warnings and recent pilot reports are folded in, and the forecast refreshes as departure gets closer. Before you board, Smooth saves it for offline use. In the air it follows your flight by GPS, which works in airplane mode, and counts down to the next rough stretch on your Lock Screen and Dynamic Island. Tap "What's happening?" for a calm explanation of each kind of bump. Your phone measures the bumps you actually feel, and after landing you get a report: forecast versus felt, and a smooth score. Smooth is guidance, not a guarantee: keep your seatbelt fastened and follow your crew.
