The next
software update for iPhone and iPad will allow the devices to know when it is
night time, and turn off the blue parts of the light coming from the screen a change that Apple says makes it easier to sleep after using the
screens in bed.
iOS 9.3
will use the device’s clock and location to
work out when the sun is setting. Then it will shift the colours towards the
warmer end of the light spectrum, making the screen easier on the eyes after
the sunset and making it more like the ambient light.
When the
sun comes back up, the colours shift to normal. It's a lot like f.lux, an app
for desktop Macs and PCs that many people find completely essential for
reducing eyestrain when using their computers at night.
Apple is
also using iOS 9.3 to show off an early version its new iOS in Education
features, which make iPads easier to use in the classroom. Students will be
able to log in to any iPad in the classroom with their own accounts, and
teachers will be able to share student iPad screens among the whole class.
It's a
shot across the bow at Google's massive success in the classroom with its cheap
Chromebook laptops.
The Notes
app is also getting an upgrade to let you place notes with sensitive
information -- bank passwords, for instance, or somebody's social security
number -- behind a password, or even require an Apple Touch ID fingerprint.
Meanwhile,
the News app gets better personalization features to better tailor the articles
it finds to your interests, while the Health app will suggest third-party App
Store apps with which it can integrate.
Apple's
CarPlay car operating system is getting an improvement, too, with a new feature
called "Nearby" for Apple Maps that shows everything around you,
alongside new music recommendation features in Apple Music.
