FaceTime calls using SharePlay

Extending FaceTime access beyond Apple

In the history of FaceTime, it is the first time Apple is extending its services beyond its closed Apple ecosystem. By using an iPhone, iPad or Mac, users will be able to generate a link and share it through Messages, Mail, Calendars or any third-party messaging app for people with an Android or Windows smart device to open the link from their browsers and join in on the fun. Facetime calls are end-to-end encrypted, so it manages to maintain its credible iPhone privacy settings.

FaceTime Audio improvements

  • Voice Isolation – You must have frequent complaints about too much background noise during a video call, making it difficult to understand what the other person is trying to say. Apple found a workaround for this. Using their machine-learning-based Voice Isolation, Facetime distinguishes the wide spectrum of different noises that your mic captures, block out the ambient noise, and prioritizes your voice. This new iOS feature helps in the communication becoming crystal clear.
  • Wide Spectrum –  Opposite to this, at times, you might want to capture all the noises during a video call; for this, Apple launched their latest iOS feature called Wide Spectrum that captures your voice and everything around you.
  • Spatial Audio –  Audio pinpointing doesn’t get more real than this. Apple introduces another latest iOS features Spatial Audio that makes each participant’s audio contributions feel like they’re coming from where they are seated in their FaceTime call frame.

IV. Features of Monetery for MacOS

Apple’s MacOS is one of the hottest trending software that catches the eyes and attention of users and developers alike. It powers one of the best computing systems in the world – their iMacs and Macbooks. In the WWDC 21, Apple announced their latest OS of Mac named Monetery for the Mac ecosystem. There are many new improvements, additions and changes that will impact how you interact with your Mac. Let’s dive right into it –

The new Xcode Cloud

Xcode Cloud

Xcode Cloud is a continuous integration and delivery service that is directly built into Xcode. You will be able to use this service to increase the development and delivery of top-quality apps by bringing together all the cloud-based tools needed to build your apps, run automated tests parallelly, distribute the app to the testers and get user feedback once place.

Introducing AirPlay on Mac

Monetery brings AirPlay to Mac, allowing users to play and share music, movies, games, images, presentations and much more from their iPhone/iPad straight to their Mac. You can also use Mac’s sound systems as AirPlay’s speakers. This enables users to use their Mac as a secondary speaker too if they need to.

On-Device Dictation with Monetery

Keyboard dictation is easy to use and also a secure way of getting things done. It protects user’s privacy by performing and processing all functions entirely offline. Monetery macOS allows users to dictate at endless lengths without any timeout.

Portrait Mode on FaceTime

Potrait Mode on FaceTime

This feature is limited to M1 Macs running on macOS Monetery, but they will be able to blur the background while using a video call during their FaceTime sessions.

Live Text in Photos

Live Text in Photos

Similar to the capabilities of Live Text for iPhones, users will be able to interact with text in photos by copy-pasting them, looking them up and translating text too. It will work on Photos, Screenshots, Safari and Quick look.

Maps for M1 Macs

Maps for M1 Macs

Again, exclusive to M1 Macs, users will use the new interactive globe with immensely detailed city experiences. Users will explore cities like Los Angeles, San Francisco, London and New York with intricate details of the roads, trees, landmarks and buildings.

Object Capture in Monetery MacOS

iOS developers will be able to convert their 2D images into a photorealistic 3D AR-based smart object in a matter of minutes with their Monetery MacOS.

V. Privacy Features of iOS15

One primary reason people prefer the iOS operating system over Android is the immense and detailed privacy and iOS security features Apple offers with its devices and services. Apple has been setting the benchmark for security and privacy services since its inception. iOS 15 is no exception; infact, there are some ground-breaking latest iOS features with respect to privacy this year. Let’s have a look at them –

Mail Privacy Protection

Mail Privacy Protection

Apple’s in-built mail app has been getting a lot of attention lately. This will only increase by introducing the all-new Mail Privacy Protection feature introduced in the WWDC 2021. This iOS tracking aims at tracking pixels embedded in many mails. These pixels get activated when you open the mail and can fetch information like your location, choice of software platform, and other such private information back to the sender.

Many newsletters, marketers and fraudsters leverage this method to get such data points unethically from users. With Apple’s Mail Privacy Protection in place, these pixels won’t be able to fetch these data points from you. They don’t block it but route them through a relay that strips out any data gathering while preserving your end experience.

App Privacy Report

App Privacy Report

Apple is also rolling out a detailed App Privacy Report feature that enables users to keep a closer eye on all the apps and the updates they have on their devices. With this latest iOS feature, a user can see how many times an app has accessed your photos, cameras, location, contacts and microphones every week. Not only this, but the privacy report will also be able to tell you why any specific app needs specific permission. Moreover, you get a list of domains the app is in contact with and with what frequency. This will help users get a better picture of how much data grabbing and sharing each app does.

Privacy with the new iCloud+

Privacy with the new iCloud+
iCloud Private Relay

Yes, you read it right, iCloud is now iCloud+ for users that pay for their iCloud storage services. One of Apple’s key tools with iCloud+ is iCloud Private Relay, which acts similar to a VPN. It will encrypt and route your web traffic through many different locations, keeping your location private keeping your data protected from any opportunists.

The main steps in this rerouting are –

  1. Encrypting your URL and deleting identifying data like your IP address
  2. Trusted content provider – publicaly recognized providers will give you a set of temporary IP addresses similar to your region that periodically changes.
  3. Decrypting your URL so it can send you to your desired site or service.

The entire process is placed on with such finesse that even Apple themselves won’t be able to piece all the information together to get access to you.

iCloud Hide My Email

Another interesting and useful iOS feature Apple came up with when introducing iCloud+ was giving the users the ability to generate several unique, random email addresses for signing up to new apps and services. All messages sent to these random email addresses will come through to your main email address. You get the power to trash them anytime you want to cut off the conversation. This feature is going to be built into Mail, Safari and iCloud.

iCloud Home Kit Secure Video

Last but certainly not the least feature that you will get with iCloud+ is the HomeKit Secure Video that will give encrypted, secure storage for storing footage of your home security cameras. All the smart recognition processing will be done locally and not sent to the cloud, adding the assurance of trust and privacy.
