Fitbit is field testing two new devices - both of which are expected to launch in September at IFA 2016.
UPDATE: Fitbit Charge 2 and Fitbit Flex 2
Wareable has been informed by a source close to the beta testing team that the two devices, codenamed Laryon and Fermion, are being used in the wild and that "black wrist covers" are hiding them from snooping eyes. We're told that it's the same method that Fitbit used to test both the Alta and Blaze late last year.
Essential reading: Which Fitbit tracker should you buy?
The name Fitbit Laryon actually appears on some legal documents to do with the lawsuit the company is involved with Jawbone with, but this is the first time we've had wind of the Fermion codename.
Fitbit has used atom-themed internal monikers for its devices in the past - the Alta was referred to as the Lepton (a half-integer spin particle) - and both Fermion and Laryon fit this theme: both are types of subatomic particles.
We have also learned that two new Fitbit trackers will go live in Berlin at IFA 2016 and, with the recent trademark applications for Fitbit Flex 2 and Fitbit Charge 2 being uncovered, we're sticking our neck out and suggesting these are the two devices that the Laryon and Fermion will become.
At this stage, we don't have any more details but we'll update this story if/ when we do. Team Wareable will be reporting live from the IFA conference and showfloor from 31 August.
