Background/Objectives: Wearable fitness trackers (WFTs) are growing in popularity as tools to motivate physical activity and support healthier lifestyles. Evidence suggests that they can have both positive and negative effects on user behaviour and well-being. However, little is known about their impact in Saudi settings, considering its unique cultural context. This study aims to investigate the perceived positive and negative impacts of WFTs on adults’ health behaviours and well-being in Saudi Arabia. Methods: A cross-sectional survey was conducted among Saudi adults aged 18 years or older who currently use or have previously used WFTs, using an online questionnaire distributed via social media platforms in May 2025. The survey was developed based on evidence from the literature. It included demographic items, five-point Likert-scale questions assessing positive (9 items) and negative (10 items) effects of WFTs, and an open-ended question. Responses were analysed using descriptive statistics, independent samples t-tests, and one-way ANOVA. Results: A total of 154 adults participated. The mean composite score for positive effects was 3.26 (SD = 0.73), indicating general agreement on the benefits of WFTs, while the negative effects score was 2.15 (SD = 0.66), showing low endorsement of adverse outcomes. No significant differences appeared between gender (positive: p = 0.34; negative: p = 0.24) or age groups (positive: p = 0.56; negative: p = 0.19). However, users of over two months had higher positive scores (M = 3.43, SD = 0.66) than newer or former users (p = 0.01). Open responses showed 62% positive experiences; 27% reported stress, guilt, or obsessive monitoring. Conclusions: This study provides initial insights into WFT use and perceptions in Saudi Arabia. However, its cross-sectional nature limits the ability to draw causal conclusions. While most users experienced beneficial health outcomes, a significant proportion reported negative psychological experiences. These findings highlight WFT users’ dual experiences and the need for further longitudinal research and diverse recruitment strategies to better understand sustained engagement and psychological effects.
