Aim: To review various consumer-level technologies for management and continuing case of obstructive sleep apnea (OSA) patients. Background: Recent advancements in wearable and smartphone technology have created new ways to assess sleep health, including OSA. Obstructive sleep apnea leads to continuous upper airway obstruction during sleep, producing episodes of apnea–hypopnea, sleep fragmentation, nonrestorative sleep, and excessive daytime somnolence, leading to long-term cardiopulmonary complications. This review sheds light on the use of modern smartphone-based sleep-tracking applications and consumer devices in the management of OSA. Results: Rapid advancements in mHealth technologies have enabled users to self-monitor and visualize their sleeping patterns, symptoms, and behavioral data, enabling them to take everyday precautions. Various available options include plethysmography, actigraphy, pulse-oximetry, ambulatory ECG recorders, body temperature sensors, sound analysis, and cardiorespiratory coupling. Conclusion: Due to limitations in precision and standards, such tools may not be recommended for clinical populations or as diagnostic tools. Future research should focus on analyzing the effect of these interventions on persons who already have good sleep quality or who use the applications but skip days. In addition, comprehensive studies measuring behavioral changes in various age, gender, and comorbidity groups are warranted. Clinical significance: While technological aids help in better management, it is vital to develop efficient methods for integrating wearables’ data into patient-care pathways. Restrictive IT infrastructures, privacy, data protection, and data ownership arguments prevent widespread integration of consumer wearables into clinical workflows.
