Hello, iPhone 11 Pro and 11 Pro Max

True to rumors, the company showed off the iPhone 11 Pro and iPhone 11 Pro Max -- and these models are all about the camera. Tim Cook, Apple's CEO, called the Pro models "the most powerful and most advanced iPhones we have ever built, with a stunning design."

The devices come with three cameras on the back positioned in a square layout. It shoots nine images and Apple's neural engine optimizes them together to get the best possible shot. "It is computational photography mad science," an Apple exec told attendees.

Not surprisingly, the iPhone 11 Pro is faster and more efficient, too. Apple (AAPL) says the iPhone 11 Pro will last four hours longer than the iPhone XS and the iPhone 11 Pro Max will last five hours longer than the iPhone XS Max.

The iPhone 11 Pro line comes in a new color: green. You'll be able to grab one in silver, space gray and gold, too.

Apple just unveiled a Night Mode for its iPhone 11

The newest iPhones will be able to see in the dark. Apple (AAPL) just revealed that its iPhone 11 will have a Night Mode on its cameras.

The mode allows you to take shots in the dark, but have them appear well-lit. (Above left is a photo in the dark without night mode, and on the right is the same photo with night mode.)

Apple isn't the first to do this. In November 2018, Google added a feature called Night Sight to its Pixel phones that does pretty much the same thing.

Next up! Meet the iPhone 11 lineup

Now on to what we've been waiting for: Apple's iPhone presentation. "It's become so essential to people all over the world," Apple CEO Tim Cook said. "It's made a profound impact on our daily lives."

What you need to know:

The iPhone 11, which looks nearly identical to last year's line on the surface, features a 6.1-inch Retina display, spatial audio to create an immersive sound field around you and new cameras positioned on the back, including a new wide camera for faster auto-focus and an ultra wide camera for capturing more in photos. The selfie camera can now switch to landscape mode and take slow-motion shots.

The iPhone 11 is also getting new colors, including green, yellow and purple.

It starts at $699.

This is the next generation of the Apple Watch

We just heard about the Apple Watch's health impacts. Now we're finding out what updates the hardware is getting: Apple Watch Series 5.

Series 5 will have a new Retina display that is always on. That means the watch face is always visible. It has 18 hours of battery life.

The cellular version has a new emergency SOS feature for when you're traveling internationally to over 150 countries, where you can press and hold down the side button to contact emergency services -- without needing your iPhone.

The GPS version starts at $399, while the cellular model costs $499. Series 5 is available starting today, and will hit stores on September 20. The Series 3 Watch will now cost $199.

Apple TV+ includes original shows from Oprah and is cheaper than Netflix

Apple announced a release date — November 1 — and a price for its TV subscription service, $4.99.

For that price, it runs cheaper than competitors like Netflix, Hulu and Disney+. But it doesn't have "Friends" to stream.

Instead, on Tuesday, Apple confirmed its lineup of original programming, including shows it had teased for months: Documentaries from Oprah Winfrey, a new Peanuts original called "Snoopy in Space" and "The Morning Show," a drama that stars and is executively produced by Reese Witherspoon and Jennifer Aniston.

How many iPhone 11s could Apple sell?

This is expected to be the third straight year in which Apple (AAPL) maintains the current design of its iPhone. Yawn.

But one Apple bull thinks people won't find the iPhone 11 to be boring at all. That's because about 1/3 of the 900 million iPhone owners will be ready to upgrade their phones over the next year to 18 months, according to Dan Ives, Apple analyst at Wedbush Securities.

"Cook & Co. recognize this will be a crucial product cycle on the horizon that we believe could translate into roughly 180 million iPhone units sold in 2020," Ives said.

That's a lot of iPhones. Suppliers are planning on selling about 75 million iPhone 11s this year, according to Ives. That's slightly more iPhone XR and XS phones than Apple sold in 2018.

Apple Watch doubles down on health tracking

The Apple Watch portion of the event kicked off with a promotional video of customer testimonials about the real-world impact of wearing the device, from flagging early sides of a heart attack to helping a pregnant mother know she needed an emergency c-section. "Hearing these stories just make my heart sing," Tim Cook told attendees.

The company also detailed how the Apple Watch is being used to in health research, including hearing, heart and fertility studies. A new research app called Studies, which will be open to Apple Watch users, will launch later this year.

Apple unveils 7th generation iPad

Cost? It will start at $329.

It's available for pre-order now and will ship at the end of the month.

Keep an eye on Apple's stock price

Apple's (AAPL) stock was down just a hair as it started unveiling Arcade, a new iPad and a number of other products. Then it ticked higher.

Typically, on days when Apple launches a new iPhone, Apple's stock has risen an average of 1.5% over the past seven years — since the iPhone 5 debut — according to Refiniiv.

The biggest iPhone launch stock move came on September 10, 2013, when shares fell 7.6%. That's when Apple launched the disappointing 5C (the plastic one) and the iPhone 5S. So we're not close to that today: Apple's only down less than 0.1%.

The best day came on September 10, 2015, when Apple launched the iPhone 6S (the one with 3D Touch). Apple's stock rose 3.7% that day.

“Today’s iPhone launch should be a boon for Apple shares," said David Aurelio, senior manager of equity markets research at Refinitiv.
