Wearable Health

For a few years now I have “worn” a Fitbit One (carried in a pocket at least) most days. Relatively recently, my Pebble Time Steel watch added step tracking too. So, now I am typically wearing two devices that track my daily steps. Comparing them provides some interesting differences.

In a typical week, the Pebble tends to read slightly higher than the Fitbit, mostly because I wear it all night for the sleep tracking feature (sleep tracking is a whole separate article), so it captures anywhere up to 1000 extra steps that the Fitbit misses while I am not wearing it. 

Los Angeles Vacation 

Last week I was on vacation in LA with my family. The week consisted of a few different types of days that really highlight some of the differences. 

Here is the Pebble Health view of the week in Los Angeles:


That’s a pretty consistent number of daily steps. Monday an Friday we were at Disneyland & Disney California Adventure respectively, and we walked a lot. Tuesday through Thursday we were at the Great Wolf Lodge, and spent a lot of time in their indoor water park. While that involved some walking, it certainly didn’t feel anywhere close to the Disney park days. (The Sunday at the start & Saturday at the end were spent driving there & back, but we made several stops.)

The Fitbit captured a very different view of the week:


The most obvious difference is the much higher values for Monday and Friday, but also notice Tuesday through Thursday are lower on the Fitbit. 

Why the Differences?

The three days with low numbers while at the water park hotel are the easiest to explain: the Fitbit One is not waterproof, so it spent all the time we were in the pool areas locked in our hotel room. So, all the walking between pools and around the pools with the kids were missed. The Pebble is waterproof and I wore it the entire time we were in the pool. Not being waterproof is, in my opinion at least, a big limitation for a health tracking device. It is also pretty important for a watch!

The huge discrepancy on the Disney days might have had me puzzled if I hadn’t seen this before. The Fitbit is in my pocket, but the Pebble is on my wrist. While we were at Disney we had a stroller for our two year old and for some of the time each day I was pushing her around in it. Anchoring my wrist. I have seen this before with strollers as well as shopping carts. It seems to be a limitation of wrist worn step trackers.

Regular Weeks

On regular weeks, the differences are mostly irrelevant though. Here is the Pebble’s view of this week:


And the Fitbit saw this:


The first three days of this week have been regular commute days for me, walking between home/office and either the ferry terminal or bus stop. Tuesday I took the bus in to work (the bus terminal in SF is much closer to our office than the ferry terminal). 

Pebble Thoughts

Black Pebble Time SteelIt is always a sad day when a company needs to trim staff, but at the same time it is sometimes very necessary to make sure expenses are inline with expected revenue. Today Pebble announced they were cutting 40 people from their workforce (25%). That’s a deep first cut, so hopefully for those left it will be the only one. The smart watch market is a strange one though. Even with the Apole watch (or perhaps partly because of it), the mass market adoption has been slow. 

What Pebble Does Well

Full disclosure here, I’ve had three Pebbles now (an original, from the first Kickstarter campaign), a Steel and now a Time Steel. For me the Time Steel is still my preferred smart watch. It isn’t perfect, and we’ll come back to that later, but it does everything I need. 

Battery life is top of the list for me. Even with plenty of notifications each day, I am getting over s week between charges. That is fantastic for somebody who carries two phones always (and sometimes more if I am testing things for work). Less devices to forget to charge every night is better. 

Close second would be the always on screen. I don’t want to have to make a conscious effort to look at the time. A quick glance gets me the time, and it is even clearer in sunlight than not. At night, I do still need to move my wrist to get the backlight, but a gentle twist works.

Notifications are the “killer app” for me, and the Pebble excels at them. If they appear on my iPhone’s lock screen, they appear on the watch. If the phone rings (very rare occurrence for my phone), I can see the caller ID on my watch & accept or decline the call (if I accept, I still need to get the phone out or put on the headset to actually talk). Since I am on AT&T, I also get the option of voice replies to text messages. That works most of the times I’ve tried it, but I don’t find myself using it much.

Waterproof. It is really waterproof. I can swim in it and not worry. 

What Could Be Better

The screen. Perhaps this is a case of the low power displays just not being as high density yet, but a really high density display (say 4x the number of pixels) would really shine. As would having the screen fill more of the face area; the large bezels are not great.

The software. Connectivity issues have been an issue for me on all my Pebbles and while the phone side is at least partly outside of their control, keeping the two devices connected and talking is job number one for a smartwatch. Additionally, not interfering with other Bluetooth devices is a must. Especially headsets and Bluetooth audio devices, both of which I have had issues with along the way. 

I would like to see some of the health information, like step counts, be included in watchfaces (maybe this can already be done and I just need to find, or write, a face that does it).

The Other Stuff

Health metrics is becoming a bigger space it seems, and Pebble was certainly late to the party. The activity & sleep tracking in the newer watches is a good start though. Personally, heart rate tracking doesn’t bother me, but that is not true for all. (If I had it, maybe I would feel differently too).

Timeline is another thing I don’t really use. The concept is good, but I am much more notification driven. Well timed calendar notifications work much better than me remembering to scan a list of events. 

Watch design is something I’ve seen Pebble be criticized for. The Time Steel looks OK to me & in fact is often mistaken for an Apple Watch at first, even by folks wearing an Apple Watch. The only real criticism of the design is the bezels. Smaller would be much appreciated! The screen really needs to get as close as possible to the outside edges of the face. I think the three new watches are a big step forward in design from the first two & I hope the design aspect will continue to improve. The look of the watch is very important. 

Carrying on from the look of the watch, the bands on the Time range (and the original Pebble) are all standard ones, with the included band on the Time watches coming with quick release pins. My Time Steel is on a third party nylon mesh band, and there are so many options out there at every price point and in all materials that it is hard to choose. If you go with quick release (sadly not available for my nylon band, though I am planning a mod to fix that), then you can change them in seconds for a different look.

Apps on the watch are not a big deal for me. I have two that I use (assigned to the shortcut buttons): the built in Health app for tracking  sleep & activity and Leaf, an app that connects to our home Nest devices. There are lots more available, but few that I really want on my wrist. Definitely not any web content reading or video apps!

Watch faces are something I’ve tried lots of (though still a tiny percentage of what is available in the store). I have my favourites, and switch between them occasionally. I also take a look in the store quite often to see what is new. 

The Future

I hope this downsizing is indeed a “right sizing” and Pebble can keep going strong. They have come so far, and I believe continue to supply something that the other contenders still cannot match (always on screen & a week of battery life), it would a shame to see them fail now.

The mass market appeal of wearables though is much harder to pin down. Health & fitness tracking will appeal to some, but I fear the things I value most in my Pebble will never be seen as more than nice to have (if that) by most people. Maybe the key to success for now is targeting the early adopter with a slightly higher end product. Early adopters will pay  more than the mass market & will upgrade more frequently. I am hoping Pebble isn’t planning to morph into another fitness tracking company with watch features.
