Personalized fitness apps

If this sounds familiar, that's because a number of exercise apps and devices have offered personalized workouts for a fee, in some cases for years. Strava, for example, is a monthly app that users can join for free. It works on both the Apple Watch and Fibit devices, among others. Strava also has premium services, called Packs, which start at $2 a month and can include workout analysis and training plans.

Vi, another example, is a wearable Bluetooth-connected headset launched in 2017, offering personalized fitness workouts, voice control, and targeted goals, including reducing stress or boosting fitness. Vi also comes with 12 months of free service, which after that kicks in at $9.99 a month, like Fitbit's new program.

Fitbit is in third place behind Apple and Samsung in the global smartwatch category according to an August report from Strategy Analytics. The device maker has in fact slipped, noted the report, dropping from 15 percent of the global market in the second quarter of 2018, to 10 percent for the second quarter of 2019. Apple grew 50 percent, in comparison, for the same period — with Samsung more than doubling its share.

The new Fitbit Versa 2 borrows from the Apple Watch by adding a smart assistant to its round of features. While Apple Watch users can tap Siri for help with sending messages and running their day, Versa 2 users will be able to use Amazon Alexa — but some features, like sending text messages, will only work for those who have Android phones.

The Versa 2 itself will be available starting on September 15, 2019 The coaching tool, where people can actually talk to a trainer, won't be available until sometime in 2020.
