Garmin Vivofit, or Farewell to my FitBit Flex [Updated]

It pains me to say, but I think I am moving on. I have been using a Fitbit device every day since January of 2012 as I mentioned in my two podcast appearances on RunBuzz and Everyday Runners. It was a critical device that combined with MyFitnessPal enabled me to lose substantial weight and ultimately become a runner.

But, sadly I have now gone through 3 of them and they are not cheap to replace. The first one a FitBit Ultra literally broke to pieces and I had to strap it together with packing tape. The second one, the FitBit One squirted out of the stupid belt clip and vanished into the ether. And now the third one, a FitBit Flex will not hold a charge. Of course I am outside of any warranty.

This got me looking around and I started to really wonder about the Garmin Vivofit. Pete Larson wrote the review Garmin Vivofit Activity Tracker Review: A Runner’s Perspective and that sent me into action. I had a rewards kickback from BJs and they just started carrying them, so I decided to try one.

Since I am already in the Garmin ecosystem, it was really the only other option for me (I had a Striiv for a while and had a terrible time with it).

Since I am a bit obsessive about my step tracking, I decided to wear both of them on my wrist for the rest of the day when I bought the Garmin. Then I decided that I really should keep wearing them both overnight and all day the next day so I could get a true side-by-side comparison. My wife thought I looked quite silly, but she is getting more used to my foibles.

The first day I wore them together, I didn’t do any running. The step count was extremely close Fitbit 6127 and Vivofit 6105. Now, I did have to bounce the Vivofit up and down just over 2000 times to get the steps to sync when I got the new device, so obviously, it’s not apples to apples.

On the second day, I started to see the real differences between the devices. First, the way they handle sleep tracking is different. Fitbit gives specific data along with graphs while Garmin Connect only shows a graph. I find this to be a real shortcoming for the Vivofit.

Vivofit sleep information appears on Garmin Connect. It looks nice, but lacks the specificity of Fitbit.

Notice the problem with the type of data. The chart on Garmin Connect looks nice, but it lacks details. This causes the results to be misleading. If you go by the Garmin Connect chart, I slept 7 hours and 25 minutes. A decent nights sleep — I prefer 8, but can get by on 7 fine.

But the Fitbit data shows a different story. It has a total of actual sleep being only 6 hours and 43 minutes. This is a big difference. It also gives actual times awake and the number of times being restless. You can try to extrapolate this information from the Garmin chart, but why?

Since Garmin has the data to make the chart, why can’t they just provide the raw data?

The stats also diverge when it comes to trends over time. Garmin gives the very basic number of hours.

Fitbit on the other hand gives very specific information. I find it remarkable that Garmin makes watches that track numerous variables like heart-rate, cadence, time, distance, and now even vertical oscillation, VO2 Max and ground contact time. Yet, they give such rudimentary information for the Vivofit. It’s almost like there are different development teams for each device. Hopefully this changes over time.

Moving on to step tracking. This gets interesting. On day two, I ran just over 6 miles and had both devices on. The rest of the day was moderately active. Fitbit steps versus Vivofit. They don’t exactly line up (Fitbit is on the left).

There’s almost a 2000 step difference or nearly a mile. What is really interesting is that I decided to compare the Fitbit app alone using the M7 chip in the iPhone 5S against the Garmin Vivofit. The resulting discrepancy is reversed as shown below.

The difference is nearly a mile and a half… How far did I walk? I have no idea. I guess I will just have to try and make it a lot and let the differences sort themselves out.

When it comes to a step breakdown throughout the day, Garmin Connect does an excellent job of displaying data.

You can easily see how your activity is spaced throughout the day and each bar displays actual numbers if you hover. I especially appreciate the Breakdown screen which offers a basic snapshot of activity balance in a day.

Fitbit does a great job as well, giving a straightforward view of activity throughout the day, but I give Garmin the edge.

Another option that both Fitbit and Garmin Connect offer are badges. I stopped tracking my Fitbit badges a while ago because I have had one a long time and attained many of them.

My Garmin badge collection has just started, so I’ll have to see what they offer over time.

The big differences between the Garmin Vivofit and the Fitbit Flex has to be the screen and battery life. The Vivofit has an easily readable screen that even has a red bar that builds across to help inspire the wearer to get moving.

The Flex has a series of dots that symbolize 2000 steps for each. The Vivofit also has screens to display the number if steps away from your goal, the number if miles, calories burned, time of day, and date.

For me, the blockbuster feature that has sold me on the Vivofit is the amazing battery life and the fact it is replaceable. The Fitbit Flex has a built in battery that I had to charge every 4-5 days. Of course, it would lose it’s charge at the most inconvenient time. I would forget that I had it charging and then start walking around without it — thus not tracking my steps.

Garmin claims that the Vivofit battery can last up to a year. If it only lasts half the time, that’s a huge win for me. Plus, the battery is replaceable. Maybe I won’t have to replace this device. I can just change the battery.

It wasn’t an easy decision to go with the Vivofit, but the battery life is what ultimately won me over. Now I just have to find more stepping friends who have the Vivofit…

UPDATE: Ray Maker aka DCRainmaker also reported that you can get the Vivokeeper, a free safety band to prevent the clasp from popping apart accidentally for free from Garmin.

    Selling price is now $90+tax. That gets one a dumb step counter. If one installs the “free” sw in exchange for garmin plundering all kinds of data from ones mobile or fixed computational/communicative device garmin will turn on the clock if things work. The sw will do simple arithmetic.

    Does very little costs way too much for what it does and wants to own all your data. For suckers only. I got this as a gift and it was way overpriced to me.
