Jawbone UP4 Recensie | 171 Gegevens vergelijking

The Jawbone UP4 is a sleek, wrist-worn fitness tracker evaluated by PCMag Australia for its design and wellness capabilities. A major pro of this device is its stylish appearance and highly accurate sleep tracking functionality. It monitors steps, tracks passive heart rate metrics using five bioimpedance metal sensors on the underside of the band, and boasts an impressive seven-day battery life. Additionally, it integrates a convenient near-field communication (NFC) chip, allowing users to make contactless payments directly from their wrist without carrying a wallet. Despite these advanced features, the tracker carries several prominent cons that impact its overall value. The device lacks a digital display screen, forcing users to rely entirely on a smartphone app to check their real-time progress. Its physical design can be uncomfortable, featuring a complicated looping clasp rather than a standard watch buckle. Furthermore, the heart rate monitor only records passive data and cannot measure pulse on demand or continuously during workouts. Finally, the contactless payment option is strictly limited to American Express cards, and reviewers concluded that competing models on the market offer significantly better...

The Jawbone UP4 is a sleek, wrist-worn fitness tracker that excels in style, sleep tracking, and its useful Smart Coach feature. Retailing at $199.99, it features a flexible medical-grade TPU strap with an embedded central module that fits wrists from 5.5 to 7.4 inches. A standout capability is its built-in NFC chip, which allows users to make contactless payments directly from their wrist at checkout counters. Additionally, the device offers a reliable 7-day battery life and works seamlessly with both Android and iOS smartphones. Despite these positive features, PCMag rated the device an average 3.0 out of 5 due to several notable limitations and a lack of competitive value for its price. A major drawback is the lack of a display screen, meaning users must rely entirely on their smartphone to view data. While it tracks passive heart rate, it cannot measure heart rate on demand or during active workouts. Furthermore, the tracker is noted as not particularly comfortable to wear, and its NFC payment functionality is highly restrictive because it exclusively requires an American Express card. Ultimately, the review...

The Jawbone Up4 ($199) is a premium, svelte fitness tracker made of TPU rubber and anodized aluminum that passively monitors health and integrates American Express NFC payments. Utilizing five underside bioimpedance sensors rather than optical tech, it automatically tracks steps, calories, active time, sleep stages (light, deep, REM), and resting heart rate. The standout feature allows users to leave their wallet behind and tap to pay at compatible retailers by holding the band's NFC logo up to a payment terminal. It syncs seamlessly with the Up companion app, which features "Smart Coach" insights and supports multiple third-party apps like MyFitnessPal and Strava to build a holistic health profile. The major pros include its comfortable, low-profile design that easily blends with everyday outfits, a solid one-week battery life, and seamless, rapid NFC payment execution. However, the review highlights several cons: the updated hook-and-eye closure remains tricky to fasten with one hand, and the band must be worn uncomfortably tight against the skin to guarantee accurate bioimpedance readings. Additionally, athletes may find it limiting because it lacks a display, built-in GPS, stair-climbing...

In this review, Josh Rubin details how Jawbone addressed major usability issues in its newer generation of wearables (UP2, UP3, and UP4) through a critical over-the-air firmware update and design hardware revamps. Previously, a major con was the highly unreliable touch interface, which required a fussy double-tap gesture to shift between activity and sleep modes. This gesture frequently failed to respond or accidentally switched modes when jewelry or the user's wrist brushed against the device, leading the reviewer to temporarily stop wearing the UP3. The new firmware update introduces a significant pro by bringing automatic sleep and wake detection to all models, entirely eliminating the frustrating manual mode switching. Additionally, the update introduces valuable feature upgrades and aesthetic improvements. A major pro for UP3 and UP4 owners is the inclusion of daytime passive heart rate tracking, making better use of the device's cutting-edge sensors instead of restricting heart metrics to when the user is asleep. On the hardware front, the UP2 ($100) receives a redesigned band featuring a lighter dual-strap aesthetic and a more secure hook clasp that elevates it...

The Jawbone UP4 is a sleek, wrist-worn fitness tracker priced at $199.99 that excels in style, advanced sleep monitoring, and contactless payments. A major pro of the device is its ability to track light, deep, and REM sleep phases, which seamlessly integrates with the highly praised, well-designed Jawbone UP mobile app and its helpful Smart Coach feature. It also boasts a solid seven-day battery life, outlasting many competitors. Additionally, it features a built-in NFC chip that enables users to make tap-to-pay transactions at participating retail locations without needing a phone nearby. However, the reviewer highlights several significant cons that make the device a poor value for the price. A primary drawback is the lack of continuous or on-demand heart rate tracking; it only records passive heart rate periodically, and the under-band bioimpedance sensors can cause uncomfortable red welts on the skin. Furthermore, the device completely lacks a traditional display screen, relying instead on three simple LED indicator lights, meaning users must check the app for all real-time stats. The proprietary clasp is difficult to fasten with one hand, the Bluetooth...
