Kardia Band for Apple Watch→

Interesting idea for an Apple Watch band by AliveCor: the Kardia band will allow users to capture EKG directly from their wrist by placing a finger on the band for 30 seconds.

Users can record a single-lead EKG by simply touching Kardia Band’s integrated sensor that communicates with the Watch app, Kardia by AliveCor. The Atrial Fibrillation (AF) Detector then uses Kardia’s automated analysis process (algorithm) to instantly detect the presence of AF in an EKG, the most common cardiac arrhythmia and a leading cause of stroke. Also included is the Normal Detector, which indicates whether your heart rate and rhythm are normal, and the Unreadable Detector, which tells you when to retake an EKG so physicians receive only the highest quality recordings.

Users can also record voice memos on their Apple Watch to accompany each EKG that give doctors and caregivers a clearer picture of what was happening at the time of the recording — describing symptoms such as palpitations or external factors like caffeine intake. Kardia also integrates seamlessly with Apple’s Health app to include EKG data with steps and calorie intake to provide richer, personal analysis over time.

The Kardia band isn’t meant for fitness aficionados – rather, it’s designed for people with heart-related problems who would benefit from medical-grade EKG and the ability to store detailed reports and notes (including voice memos dictated on the Apple Watch). I’m curious to see if more companies (including Apple) will come up with Apple Watch bands with embedded sensors that can transfer data directly to the Watch (there were some rumors about this last year).

Also worth noting: AliveCor is run by Vic Gundotra (former Google VP and head of Google+) and they have a whole line of Kardia products (which also include smartphone cases for similar measurements).

Watch Apps Worth Making→

David Smith:

What doesn’t work is easiest to say. Apps that try to re-create the functionality of an iPhone app simply don’t work. If you can perform a particular operation on an iPhone, then it is better to do it there. The promise of never having to take your iPhone out of your pocket just isn’t quite here yet. The Apple Watch may advance (in hardware and software) to a point where this is no longer true but the platform has a ways to grow first.

There seems to be only three kinds of apps that make sense given the current hardware and software on the Apple Watch.

Bingo. As I tweeted yesterday, my favorite Watch apps aren’t trying to mimic iPhone apps at all. If the same task can be completed on the iPhone, I don’t see why I would try on a smaller, slower device.

The best Watch apps will be the ones that wouldn’t be possible or make sense on an iPhone.

HeartWatch 2 Review

A couple of months ago, Federico linked to David Walsh’s Medium post detailing HeartWatch, a deeply functional heart monitoring app. HeartWatch, according to Walsh, is a better way to visualize heart rate data pulled from your Apple Watch.

Now in version 2.0, HeartWatch looks to be a more all-encompassing aggregator of your heart information. After spending some time with the newest version of the app, I can highly suggest HeartWatch – not only for its capabilities but also for its potential.

Sleep++ 2.0 Brings Improved Sleep Analysis to Apple Watch App

I’ve previously noted how, almost a year into the Apple Watch, I haven’t found myself depending on any particular Watch app. I mostly use my Apple Watch for basic features such as notifications and timers, and I like wearing it because it looks nice. All the productivity or utility apps I’ve tried are either too slow, too complex for a tiny screen, or they don’t launch at all because of watchOS performance issues.

Unhand Me! – Preventing Unwanted iOS Device Handling

Unhand Me! comes at a time of Apple Watch app confusion. Some developers have chosen to create apps that keep most of their functionality for the Watch; other Watch apps are smaller versions of iOS apps with some added features.

Unhand Me!, which is an app that notifies you when your iOS device has been handled, is an attempt at the latter. Through actionable notifications or the Watch app, Unhand Me! can be a must-have for those who own an Apple Watch. But even for the smartwatch skeptics, this app is one to strongly consider downloading for the safety of both your hardware and data on your iPhone and iPad.

How Apple Watch Keeps Time→

From The Telegraph’s interview with Apple’s Kevin Lynch on the timekeeping features of Apple Watch:

Apple built its own Network Time Protocol (NTP) servers at various locations to ensure the delivered time is as close as possible to Stratum One accuracy, the time server which keeps the Apple Watch within microseconds of Stratum Zero devices - the highest possible quality for time references.

Once the time reaches the Apple Watch, the team worked to ensure it remains accurate, he says. Each device uses a temperate controlled crystal oscillator to counteract the natural drift that clocks and watches tend to experience over time.

I’m not sure any human watch wearer would ever notice a 50-millisecond difference – especially when waiting for midnight at a New Year’s Eve party – but still, fascinating tech.

HeartWatch: An Accidental but Heartfelt App→

Great story and app idea by David Walsh: dissatisfied with the presentation of heart rate data in Apple’s Health app, he created HeartWatch – a dashboard for your heart rate data. The app works best if you’re an Apple Watch wearer (you get readings every 10 minutes) and it includes features such as peak zones, timelines, and – my favorite – separate tabs for regular, waking, and workout heartbeats.

Heart Watch lets you see how your heart is beating across three simple views. Waking, Regular & Workout. Each of these views are isolated because, while you may want a higher heart rate during a workout, if your heart is racing when you aren’t doing any exercise then this is likely not a good thing and probably something you might want to show your medical practitioner.

David has shared the full story behind the creation of HeartWatch in a blog post:

Now I wanted to dig a bit further to find when and what was happening with my heart. Unfortunately, the Health app wasn’t very much help from here forward. There’s a summary graph, then to go any further, you have to read every single heart beat reading captured. With no search! Proverbial needle in haystack. So I looked around to see if there were any apps to help. Short answer. No. They seem to fall into finger on the camera apps, “fitness junkie” apps or just giving a simple average.

My research also made me realise a simple average is close to useless if you work out. Obviously your heart rate will be higher when you work out. This then throws out the daily average compared to days you don’t work out.

So I started a side project. Something that could show me what was going on. This then of course grew, as these things tend to do.

I took HeartWatch for a spin, and I like what David is doing. The app imported months of heart rate data from Health in less than a minute and it presented me with a clear calendar view of different reading types. HeartWatch can show percentage changes from previous readings, and it neatly breaks down a day’s data with colored charts and labels. I would love to see these kinds of average stats for weekly and monthly stats too, but, overall, HeartWatch is off to a good start.

Like David Smith’s Pedometer++, HeartWatch is another app that uses data from the Apple Watch in an interesting and useful way. If you care about your heart rate as measured by the Watch (and you should), I recommend giving HeartWatch a try.

Pedometer++ Gets Smarter Step Counting on Apple Watch and iPhone→

David Smith’s Pedometer++ is one of the apps that got me back in shape and I’ve always appreciated the thought and care that he puts into it.

Today, David released a substantial update to Pedometer++ with an entirely new logic to coalesce steps registered by the iPhone and Apple Watch:

You might be wondering why I don’t use Apple’s Health.app merging system for this. After extensive testing about how that works I determined that it doesn’t really do a good job for step data. The Apple Health algorithm works around the concept of a ‘priority’ device. This priority device’s steps are then used in all instances except where that device is completely unavailable. In which case the secondary devices data is used to fill in the gaps.

The concept of a fixed priority device doesn’t really work for step data. As you move between the various activities of your daily life, the best device for measuring your movement is constantly switching. Thus you need a data merging algorithm that can dynamically analyze your step data and determine which device’s data is best at any particular time.

That is exactly what Pedometer++ now does. It goes through your daily data and can dynamically determine which device to use for any particular point in your day. The result is a much richer and complete picture of your daily activity than you’d get from Health.

I’ve tried many pedometer apps for iPhone and Apple Watch over the past few months, and I’ve noticed annoying discrepancies between data recorded by my iPhone and steps measured by Apple Watch. David’s intelligent system to reconcile steps taken sounds like what I’m looking for. It’s been a while since I wanted to really check out a new watchOS app, too.
