Pitot
Pitot reads Apple Weather hour by hour against the limits you set for your own aircraft, adds the planetary K index from NOAA, and computes sunrise, sunset and civil twilight on the device. It shows the whole day as one strip of hours, the next window to fly, a ten day outlook, a pre-flight checklist and a flight log.
Pitot does not know your airspace. It reads weather. It never tells anyone a flight is safe, legal, cleared or permitted, and it draws no no-fly zones. Check your aviation authority's own tool before you fly; Pitot links to them by name.
