Xiaomi Smart Band 11 if you want a cheap watch that also measures: see the time and messages, control music and pay little. It's the best-selling band with a screen for a reason.
DuckDik Sense if what you want is to know how you sleep, how you recover and how much energy you have, without looking at your wrist or charging every week. You pay more for the band, but no fee for the interpretation.
The DuckDik Sense: up to 45 days (25-30 with intense daily training). The Xiaomi Smart Band 11 claims 10-12 days of normal use and 6-7 with the always-on display.
The Xiaomi Smart Band 11 measures night HRV in its Chinese version; in Europe it is unconfirmed as of October 2026. The DuckDik Sense computes your recovery every morning from night pulse, sleep duration and continuity.
There are no independent tests of the Smart Band 11 yet; on the Band 10, with the previous sensor, GSMArena rated heart rate as good and sleep detection as weak. The DuckDik Sense uses the same type of optical sensor; neither is a medical device.
No. Both work without paying a fee. Mi Fitness offers an optional “VIP”; with DuckDik the AI coach is included.
Official European prices as of 26 October 2026; they may change. Wellness and activity data: neither is a medical device. Xiaomi Smart Band 11 data comes from its website and independent reviews (below).
