Apple Files Patent Application for Podmaps

Having brought podcasting to the mainstream with its ubiquitous iPod, Apple has now set its new sights on a different form of portable “casting” which it has pioneered for itself. A U.S. patent application filed by Apple in January and published on Thursday describes a method for creating podmaps, pre-generated maps and corresponding multimedia content that could be pushed to portable devices together.

The concept would allow users to visit a Web site, enter a destination to get directions to, and have audio directions automatically generated by a text-to-speech engine. The resulting audio snippets would then be packaged with map data in the form of image files and moved to a portable device, such as the iPhone, allowing users to hear directions and see map images as they drive to a location, even without a live Internet connection.

The bulk of the patent application describes the technical innovations Apple designed to achieve this. Since traditional podcasts are one-way streets where users receive content from podcasters without any input, Apple’s patent covers the method for generating personalized podmaps based on user preference, but still distributed in much the same way traditional podcasts are, via Real Simple Syndication (RSS).

While Apple has not yet made any formal announcements pertaining to the technology, the patent filing could be a foreshadowing of future services to come from the company.

I keep forgetting about the Apple Watch Series 9’s coolest feature

I’m just going to come out and say it: I love the Apple Watch Series 9. A couple of weeks ago, I returned to wearing it every day after an extended period of not doing so. And you know what? I was surprised by how much I’d missed it.

But one thing has bothered me this time around: There's a feature I haven't been using. Not because it’s bad, but because I tend to forget it's there.

This one Apple Fitness feature completely changed how I exercise

I have a confession to make: I'm not good at sticking to a workout routine. I love running, high-intensity interval training (HIIT), strength training, etc. In the moment of those exercises and in the post-workout euphoria, I feel amazing. But when it comes to waking up early in the morning to do these things before work? Well, that's where I really struggle.

This has been a problem for a while now. I go to bed with the goal of waking up early and going to the gym, but as I groggily open my eyes to snooze the alarm on my iPhone 15 Pro Max, I end up falling back asleep. And I've been repeating this over and over and over again.
