EMFIT-QS-Night-Trend-Sleep-classesEMFIT opts for a subscription model

Like Whoop, EMFIT has decided that a subscription model is a better option for their business. This week they will announce the details of the new pricing structure and confirm that existing customers will be able to continue with the monitor they bought for no additional charge.

My understanding from EMFIT is that the existing EMFIT monitor is finished from a hardware point of view and that the company is able to update its features wirelessly through new firmware. I sense that EMFIT would like the security of a future revenue stream that a subscription model would bring and it seems they are implementing that in a fair way.

Today’s announcement from EMFIT won’t affect existing users who will retain a free access to the online platform.

Fitbit Smart Ring Patents Registered

Super keen journalists have been trawling through Fitbit’s patent registrations and it seems that Fitbit has filed patents for SpO2 and Blood Glucose sensing by a ring.

Patents do not always come to fruition and can merely be used to control the competition and bring future revenues from licencing. However, patents can sometimes be a good guide to new products as we saw with Shimano’s recent filings for their new Dura-Ace 12-speed wireless groupset that should be appearing this month(?).

That said, it seems highly unlikely that Fitbit would be able to release a SpO2 and Blood Glucose sensing ring even in 2022 when they don’t have a ring product at all right now. Contrast that to Apple who is rumoured to still be a long way from a Blood Glucose solution for Apple Watch.  For Fitbit to release a ring product in 2022 would face a MASSIVE catch up task to compete with the relatively basic products that are already sold like Amazon Halo and newer entrants like Circular…Fitbit has to catch up AND THEN overtake their features by adding SpO2 and Glucose.

Smart Rings occupy an interesting space in the market. There are several players, some go down the health & fitness route and others go down the tech route (Motiv) with authentication-type devices. Smart rings represent a potentially massive market and one that would be highly profitable when approached sensibly yet almost all companies seem unable to even produce a properly sized heart rate tracker.

 

AI Endurance Introduces automatic Detrended Fluctuation Analysis DFA alpha1 (DFA a1) tracking

I’ve been using AI Endurance for the last few months as a sense check for some of my workouts. I have my ‘plan’ and if I’m feeling particularly good or bad on any given day then I check to see what AI Endurance recommends instead of what is on my plan.

AI Endurance uses machine learning to determine which of your historical workouts have achieved your best outcomes that are suited toward your race goal.

Their DFA Alpha 1 announcement is the application of a mathematical method to sense the HRV changes that occur as you pass through your lower aerobic threshold (LT1, AeT) and to identify that point.

Here’s some more info behind that

  • More detailed info: AIEndurance.com
  • Connect Garmin Connect to AI Endurance (Strava will not pass HRV to AI Endurance so you can’t use that)
  • For best results, use a Polar H10 connected by BLE to your Garmin
  • Ensure that your Garmin is logging HRV (by default it is NOT logging HRV)
  • Perform a super easy ramp test indoors with a long slow progressive ramp either on a treadmill or stationary bike.

The importance of knowing your aerobic threshold (AeT) is massively important for endurance training as you want to ensure that your aerobic workouts are genuinely aerobic…go higher and you start to burn carbs.

New developer HRVAplha1 has released a CIQ widget of the same name that allows you to monitor the value in real-time.

via @pavlinux, thank you

 

 

Fat Maxxer also introduces DFA Alpha 1 functionality

Thank you to Fat Maxxer developer Ian Peake who made me aware of his contribution to spreading some DFA a1 goodness with his new Android app.

  1. I’ve been using an EMFIT device for ~4 years now, glad to see they will allow existing users to continue as is. Not sure why I’m surprised by a company doing the right thing but I am!

  2. As a long-time emfit user, I’m not at all surprised by this. Even a few years ago I was wondering if/when they would go out of business because once you buy it they are on the hook to provide the services “forever” for free, so I was waiting on the shoe to drop and the service to just go down some day, lol. Only so many people willing to buy a product like this.

    So this is great news, in fact I wouldn’t mind paying a small subscription fee even for my existing/old hardware if I got new services/analysis/etc… This is a niche product so I’d like them to stay alive.

    1. existing customers get the same deal…ie same service for free. there is no better product/service.
      the new product is sold on a subscription basis with minimum committment

      1. The subscription prices seem to be fair, since the device is already included:
        19 Euro per month for 6 months
        15 Euro per month for 12 months
        12 Euro per month for 24 months


        I already own a device would consider a subscription for 3 Euro per month if my data is stored endless. I own the device since 2015, but my data only goes back to 2018 and guaranteed is only 1 year.

  3. How much success have you had with DFA1 calculation estimates? I keep running a test with my Polar H9 chest strap per their suggestions and my AeT keeps calculating way low (like 130-131bpm whereas other tests show 142-145bpm). Wondering if it’s the Polar H9.

      1. That’s what I’m afraid of!

        After I finish this current training cycle I might try a long offseason where I train under AeT as established by DFA1 and then see what happens.

        1. P.S. Incidentally DFA1 is calculated pretty consistently spot on with what my “MAF” HR is (180 minus age) and what I trained at when previously testing out that style of training.

          1. yes my understanding is that we all think the age-XXX formulae are rubbish because we observe apparently contradictory results from our own data. However those data often assume that a) the heart rate reading is correct and b) that the reading is actually a complete heart beat.

            My thresholds have dropped over the last 10 years…am I fitter (yes) or older (yes)…maybe it’s both
            edit:yes the 180-age thing is quite similar to what dfa1 produces for me
