Fitbit today introduced a $200 smartwatch called the Versa, plus an inexpensive new fitness tracker for kids. The firm also announced a new version of its wearables platform, called Fitbit OS 2.0, that adds numerous new features.

“As the wearables category continues to grow, Fitbit Versa fills a critical need in the market by delivering a beautifully designed, full-featured smartwatch that is easy to use at a very competitive price,” Fitbit CEO and co-founder James Park said in a prepared statement. “Versa brings consumers the advanced health and fitness features Fitbit is known for, along with broad compatibility across mobile platforms and 4+ days battery life to provide users with a better picture of their overall health, making it stand out from any smartwatch available today.”

That last bit is important, as these products represent a new push against the Apple Watch, which is closing in on Fitbit’s market share. (Xiaomi is actually the world’s biggest seller of wearable devices, and by far, probably because of its base in China.)

The Fitbit Versa looks solid, and at $200, it’s fully one-third cheaper than the Ionic, Fitbit’s first smartwatch. It provides real-time heart rate tracking, onscreen workouts, automatic sleep stages tracking, quick replies on Android, wallet-free payments (on Fitbit Versa Special Edition only; this is $30 more expensive), on-device music, and 4+ days of battery life.

The Versa is powered by Fitbit OS 2.0, which provides a new and personalized dashboard for daily and weekly health and fitness stats, historical activity, heart rate, and exercise summaries, action-oriented motivational messages, tips and tricks, and daily guidance.

The Fitbit Versa is available for pre-order now. It will ship in April, Fitbit says.

The Fitbit Ace, meanwhile, is a $100 version of the Fitbit Alta fitness tracker that is aimed at children. It features up to 5 days of battery life, 10 unique clock faces, and two fun interchangeable bands in electric blue and power purple. You can preorder it now from the Fitbit website and it will ship sometime before mid-year.
