Google\'s new fitness tracker Fitbit Air showed performance similar to a high-priced smartwatch in measuring heart rate and calories, but revealed noticeable errors in running distance and pace. TechRadar ran a 10 km test while wearing Fitbit Air and Apple Watch Ultra3. Average heart rate differed by 3 beats per minute and calories were close. Fitbit Air recorded a faster pace and longer distance, and offered fewer detailed running metrics.

Google’s music-generating AI model Lyria 3 can produce about three minutes of audio with vocals and lyrics from text or images, with structure set by prompts. In a test, it generated a track reminiscent of Kendrick Lamar’s HUMBLE despite changes to the key, and handled a genre shift to orchestral accompaniment smoothly. But lyrics often did not fit melodies, and a jazz-style test sounded like a beginner’s improvisation, with repeated emphasis on a seventh tone. The reviewer said the music lacked a clear motif and narrative shape.
