Fitness trackers and smartphone apps help heart disease patients stay active, study finds


Fitness trackers and smartphone apps may be doing more than just tracking you from your wrist. A new review published in the Journal of the American Heart Association found that people with cardiovascular disease who used smartphone apps, fitness trackers, or wearable devices were more active than those who did not use digital tools.

The review looked at 14 clinical trials involving 1,057 participants with diagnosed cardiovascular disease, including coronary heart disease, heart failure, heart attack, or stroke history. Compared to people who did not use these tools, participants using apps or wearable tech walked nearly 1,100 more steps per day and added about four extra minutes of moderate-to-vigorous physical activity daily.

Why every small movement gains matter

For many people managing heart disease, small activity improvement like these can be a big deal. Many patients are encouraged to take part in cardiac rehabilitation, but traditional programs are not always easy to access. Aspects like distance, cost, time, and mobility challenges can all get in the way.

That is where phones and wearables have an obvious advantage. They are already in people’s pockets and on their wrists, and they can deliver reminders, feedback, daily step goals, motivational messages, coaching, and progress tracking without requiring a trip to a rehab center. Some of the programs in the review also used gamification, quizzes, rewards, and goal reviews to keep people engaged. In other words, the same little nudges that make your smartwatch mildly annoying during a lazy afternoon could be useful when built into a care plan.

This is not a miracle cure

The review found improvements in daily steps and activity time, but it did not find significant improvements in peak oxygen consumption or walking distance. Reasearchers noted that longer studies are needed to know whether these habits last over time and whether they lead to better long-term health outcomes.

So your fitness tracker is not a replacement for medical care, cardiac rehab, medication, or professional guidance. It is just a useful support tool. But the finding gives wearable tech a stronger case beyond sleep scores, streaks, and calorie estimates. And for those battling heart diseases, a phone app or fitness tracker helps becoming more proactive with movement in daily life.

I am a recent convert to physical media — yet even as someone getting back into buying discs in 2026, I haven’t been buying Blu-rays. Like many Americans, I still pick up DVDs instead. These aren’t great times for the Blu-ray format, and don’t expect a turnaround in 2026.

Fewer new releases make their way to Blu-ray

More media is now released exclusively for streaming

Blu-ray has been around for two decades, but it never managed to fully replace, or even overtake, the DVD format it was designed to supersede. We still can’t take for granted that our favorite movies, let alone TV shows, will eventually see a Blu-ray release.

The movies most likely to come to Blu-ray are the ones that hit theaters, but a growing amount of cinema is designed exclusively with streaming platforms in mind. I recently rewatched Mississippi Masala, which led me to check in on what work Sarita Choudhury has done over the decades since. A film called Evil Eye released in 2020 caught my eye. Unfortunately, it’s only available via Prime Video. There’s no Blu-ray or even a DVD. In contrast, it’s easy to watch Michael B. Jordan in Sinners on Blu-ray, since that movie came to theaters last year.

You could say that it makes sense that a movie with a 4.8/10 rating on IMDb doesn’t see a physical release, but in the heyday of physical video, store shelves were stacked not only with just the big-budget bangers but plenty of straight-to-DVD movies as well. Now those films exist to pad out streaming catalogs instead.

Fewer big box stores stock their shelves with physical discs

Blu-ray discs have disappeared from some stores entirely

The format’s demise is striking. I frequent my local Best Buy quite often and don’t see any movies on display. That’s because the retailer stopped selling movies in stores several years ago. Walmart still sells them, but the selection is a fraction of what you could find ten or twenty years ago. The audience has been reduced down to the shrinking number of people whose internet at home can’t handle streaming and those who might think of themselves as collectors.

If you venture onto Reddit and visit r/Blu-ray, you will find more threads about thrift store hauls and older collections than excitement over the latest new release. Don’t get me wrong — I, too, am very excited about seeing what gems I can snag for only a couple bucks, but this shows the challenge retailers face. Increasingly, only enthusiasts are prepared to drop over $20 on a disc.

The simple truth is that most people don’t want to buy physical media. Discs don’t fit in phones, and the drives are no longer available in most laptops. Even desktop PCs lack a place to put a disk. I recently built a PC for the first time in part to digitize my media library, and I rely on an external DVD drive connected via USB. Yes, DVD, not Blu-ray. A smaller file size combined with upscaling is easier on my hard drive.

Retro nostalgia hasn’t helped Blu-ray in the same way it has aided vinyl. This is in part because most people simply don’t care all that much about video quality. Most are streaming video on Netflix and YouTube at middling settings on small screens, and many of us are acclimated to mid-range phone speakers, compared to which even the subpar built-in speakers on modern TVs sound like a huge step-up. It’s hard to convince large numbers of people to purchase an expensive version of a movie in a format that requires thousands of dollars of home media equipment to truly appreciate.

4K Ultra HD is in an even worse position

It’s been a decade, yet few people own these discs

The 4K Ultra HD Blu-ray format is an enhancement, rather than a replacement, of the Blu-ray discs that first appeared in 2006. Debuting in 2016, the 4K Ultra HD format supports the max resolution of a 4K TV.

4K TVs were still somewhat of a novelty ten years ago, but they’re cheap and commonplace today. Still, people aren’t demanding 4K-quality Blu-ray movies as a result. These discs are still less common than 1080p ones, which are themselves still outnumbered by DVDs.

This isn’t merely a matter of consumers preferring the cheaper option. Often, 4K simply isn’t a choice, or it’s one that arrives significantly later, like the Switch port of a PC title. Some recent films, like Exit 8, are slated to see a physical release over the summer yet will still be in 1080p when they do. Adoption of the newest format has been that slow.

The industry isn’t helping itself, either. 4K Ultra HD Blu-ray discs come with DRM and aren’t easy to play on a modern PC, further limiting potential growth. They do not want anyone pirating these super high-quality versions. When you consider that some of these 4K Blu-rays have an AI upscaling problem, you’re paying more for what may not even be the best version.​​​​​​​


Blu-ray is seeing fewer releases, is available in fewer places, and is less accessible in the ways many of us want to watch TV shows and movies in 2026. With our portable devices getting better and internet speeds getting faster, it’s hard to see physical video staging a turnaround, even if we’re still a long way off from it going away entirely.
