Apple is now working on the all-new iOS 9.3. A raw version of the latest edition of the mobile operating system by the Cupertino tech firm has just been made available to developers and it comes with exciting new features users will certainly enjoy.

The most talked about addition from the iOS 9.3 is the Night Shift mode, which allows users to change the color temperature of the iPad or iPhone's screen.

CNET explains that this feature will help users enjoy better sleep quality by having the screen shift from bright white to eye-friendly warmer blue colors.

"Many studies have shown that exposure to bright blue light in the evening can affect your circadian rhythms and make it harder to fall asleep," Apple wrote in a blog. The tech firm aims to solve that with the iOS 9.3.

When Night Shift mode activates, the display color will switch to warmer colors after sundown using the clock and geolocation as guide.

Apple iOS 9.3 also has something for the Notes app. Users can finally put a password on their notes so as to keep the important information saved on it private.

For those who don't want to password-protect the personal data on their notes, their fingerprints will do. In addition to that, the new software now lets users file the notes by title and date.

Apple also made it much easier with the iOS 9.3 to locate third-party apps that compile their health metrics and workout schedule in one convenient place in the form of the Health app. In line with this, the software now gives users the ability to pair multiple Apple Watches to a single iPhone.

The iOS 9.3 also comes with Hebrew, Finnish, and Malay languages for Siri. The new Classroom app was also added for teachers to be able to create lesson plans and student progress right from their iPad.

No release date for the iOS 9.3 has been determined yet.
