FitBit Ionic Review

Since I received my Pebble Steel back in 2014 I knew I never wanted to go back to using a normal watch. Having notifications and apps on my wrist was just too useful to me. I skipped the Pebble Time, but when the Time 2 was announced I happily put in a preorder. Unfortunately it was not to be, and Pebble folded and was sold to FitBit. If Pebble wasn’t able to survive then as an existing FitBit user having them as a buyer is probably the the best option.

The idea of FitBit’s scale and expertise in building hardware, combined with Pebble’s excellent developer platform was an enticing prospect. Rather than switch to an Apple Watch (or Android Wear, although that would have required a new phone) I decide to wait for the fruits of the combined company’s labour to be released.

I was getting a bit itchy, and my trusty Pebble Steel was showing it’s age, but eventually the FitBit Ionic was announced. A few days before the official release date my preorder arrived. It’s now been two weeks of wearing it nearly 24/7, so it seems like a reasonable time to post my thoughts.

First impressions of the hardware are excellent. Most reviews have criticised the looks, but I’m actually a fan. I like the way the bands transition into the watch itself, and sure it does just look like a black square when the screen is off, but that’s the case for all current smart watches. The buttons have a nice firmness to them, and the touchscreen is responsive. I have had some issues swiping to clear notifications, but I think that’s more to do with the touch targets in the software rather than the touchscreen, as I’ve not had issues elsewhere.

The key hardware concerns are the screen and battery life. The bottom line is that both are excellent. The screen is bright and clear, even in strong sunlight. I’ve not tested the battery life extensively because I’m wearing it essentially all day. I only take the Ionic off to shower, and it appears to only lose 15-20% per day, and a quick 15 minute charge per day is enough to keep it topped up.

The one big element I miss from my Pebble is the fact that the screen is not always on. If you do the lift-and-twist “I’m looking at my watch” gesture then it does turn on reliably, but it’s rare that I actually do that. Looking at my watch tends to be a much more subtle movement, and then it only recognises it occasionally. I have found myself pressing a button to turn the screen on, which after having an always on screen feels like a step backwards.

At the moment it’s probably too early to comment on the software side. The core features are all there and work well. Notifications from apps, texts and calls all work. I’ve been able to track various types of exercise, including bike rides which were tracked with the built in GPS and synced automatically to Strava. Heart rate monitoring and step count also appear reasonably accurate, as you would expect given FitBit’s history.

Unfortunately the key reason I brought the Ionic – that they had Pebble’s software team building the SDK – is not yet visible. There are a small set of watch faces (I’m a fan of the Cinemagraph), and some built in apps, but as yet there’s no sign of any externally developed apps. It’s early days though, and hopefully a developer community will form soon.

So, would I recommend the FitBit Ionic? Yes, but more on potential than current execution. The hardware appears to be there, it just needs a bit more time for the software to mature and apps to be developed.

Accessing FitBit Intraday Data

JoggingFor Christmas my wife and I brought each other a new FitBit One device (Amazon affiliate link included). These are small fitness tracking devices that monitor the number of steps you take, how high you climb and how well you sleep. They’re great for providing motivation to walk that extra bit further, or to take the stairs rather than the lift.

I’ve only had the device for less than a week, but already I’m feeling the benefit of the gamification on FitBit.com. As well as monitoring your fitness it also provides you with goals, achievements and competitions against your friends. The big advantage of the FitBit One over the previous models is that it syncs to recent iPhones, iPads, as well as some Android phones. This means that your computer doesn’t need to be on, and often it will sync without you having to do anything. In the worst case you just have to open the FitBit app to update your stats on the website. Battery life seems good, at about a week.

The FitBit apps sync your data directly to FitBit.com, which is great for seeing your progress quickly. They also provide an API for developers to provide interesting ways to process the data captured by the FitBit device. One glaring omission from the API is any way to get access to the minute by minute data. For a fee of $50 per year you can become a Premium member which allows you do to a CSV export of the raw data. Holding the data, collected by a user hostage is deeply suspect and FitBit should be ashamed of themselves for making this a paid for feature. I have no problem with the rest of the features in the Premium subscription being paid for, but your own raw data should be freely available.

The FitBit API does have the ability to give you the intraday data, but this is not part of the open API and instead is part of the ‘Partner API’. This does not require payment, but you do need to explain to FitBit why you need access to this API call and what you intend to do with it. I do not believe that they would give you access if your goal was to provide a free alternative to the Premium export function.

So, has the free software community provided a solution? A quick search revealed that the GitHub user Wadey had created a library that uses the urls used by the graphs on the FitBit website to extract the intraday data. Unfortunately the library hadn’t been updated in the last three years and a change to the FitBit website had broken it.

Fortunately the changes required to make it work are relatively straightforward, so a fixed version of the library is now available as andrewjw/python-fitbit. The old version of the library relied on you logging into to FitBit.com and extracting some values from the cookies. Instead I take your email address and password and fake a request to the log in page. This captures all of the cookies that are set, and will only break if the log in form elements change.

Another change I made was to extend the example dump.py script. The previous version just dumped the previous day’s values, which is not useful if you want to extract your entire history. In my new version it exports data for every day that you’ve been using your FitBit. It also incrementally updates your data dump if you run it irregularly.

If you’re using Windows you’ll need both Python and Git installed. Once you’ve done that check out my repository at github.com/andrewjw/python-fitbit. Lastly, in the newly checked out directory run python examples/dump.py <email> <password> <dump directory>.
