Search engine giant Google at I/O 2015 developers' conference announced that users will be able to use Google Maps without internet connectivity, including turn-by-turn directions. They can also view YouTube videos for a window of 48 hours without being connected to YouTube site.

The company also announced a new photo app, named Google Photos, which provides unlimited photo storage in Google cloud and has a fast, efficient way to find and display individual and groups of videos or images.

Everything is chronologically marked and saved and by swiping down quickly, you can easily scroll through months and years of photos within seconds. By using simple keywords, you can get groups of photos that fit that description to pop up on the screen, and by pinching the screen, you can make smaller the size of the proofs to add more photos to scan.

All these new capabilities will run on Google's latest version of Android operating system, Android M, which was introduced on 28th May.

Google also introduced Android Pay, which will take the place of Google Wallet on smartphones. It seems to be similar to Apple Pay in that it will power in-app and tap-to-pay purchases on mobile devices.

However, Google Wallet will still be supported, but it will be only used to conduct Play Store purchases on web. It will also facilitate peer-to-peer payments through the app and on services such as Gmail.

Google's Internet of things (IoT) operating system, called Project Brillo, was mentioned as a derivative of Android that will serve as a low-power connector for millions of devices in the future.

The company is also consolidating more of its capabilities so that they can work in real-time fashion in an app called Google Now on Tap. This new digital assistant listens in on your activities and can combine input such as airline and train schedules, geo-positioning, news regarding traffic, weather and other factors.
