Reviewer verdict
Across 5 YouTube reviews, the Spade & Co Health Smartwatch 4 earns an Index score of 4.1/5, ranking #9 among Smartwatches. Reviewers most often praise its other, features, health tracking, while the most common criticisms concern health tracking, features.
Reviewers praise this watch for its robust hardware and extensive features. The bright, high-resolution AMOLED display is protected by durable Gorilla Glass 5, and the battery life is a standout, with some models lasting over two weeks and others offering faster charging. It delivers a comprehensive health tracking experience, covering essentials like 24/7 heart rate, SpO2, and detailed sleep analysis, alongside advanced safety features. The most notable innovation is its non-invasive blood glucose monitoring, providing on-demand readings. With compatibility for both Android and iOS, smart notifications, and Alexa integration, it presents a compelling, feature-rich package, often at a budget-friendly price point, making it a strong value proposition in the current market.
The most significant drawback is the unreliability of the marquee blood glucose monitoring feature. It is not FDA-approved and reviewers found it dangerously inaccurate, failing to detect rapid post-meal spikes and, more critically, missing hypoglycemic events by providing false high readings. The watch lacks real-time alerts or trend arrows, making it unsuitable for serious diabetes management and a poor substitute for approved glucometers or CGMs. Other minor complaints include the use of proprietary bands which limits third-party customization options and privacy concerns over server-side processing for sleep data analysis.
