Between the vívomove Trend and Ring 4, the vívomove Trend comes out ahead in several specs, while the Ring 4 wins on battery life / sport modes. Overall, the vívomove Trend scores 46.1 and the Ring 4 scores 52.9 on our Mars Score.
Which should you buy?
The Ring 4 edges ahead on the Mars Score (46.1 vs 52.9), but the 6.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The vívomove Trend does not pull ahead on any single popular-comparison spec — its strengths sit in the spec-table groups rather than the headline advantages.
Pick the Ring 4 if you care most about battery life / sport modes. Its strongest claims are battery life, sport modes, water resistance.
Both ship with comparable gps, spo2, so those specs do not separate the two — focus on the differences below.
Bottom line: the Ring 4 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
