Because of Qaly, I went to my doctor and was diagnosed with SVT and was told it was probably never an anxiety disorder. I have lived 15 years of hell thinking I was having intermittent panic attacks and agoraphobia. Getting set up for an ablation. I will be forever grateful.” — Marcie D. from Alabama “Qaly was so helpful in quickly identifying signs of a potentially serious heart condition … Without Qaly, I would have blown off the ECG and maybe shown it to my primary care doctor at my next appointment a few months away.” — Lori B. from Virginia “My Apple Watch categorizes my arrhythmia as normal or inconclusive, which makes me question what I’m feeling. Without Qaly, it would’ve taken me another 6 months to a year to take this to a doctor. With Qaly I gained valuable information. Qaly is the key.” — Jessi I. from Washington ----- Qaly members get peace of mind: • ECG analyzer for all watches and devices: Apple Watch ECG, Fitbit ECG, Kardia ECG, Wellue ECG, Withings ECG, WHOOP ECG, Garmin ECG, holter monitors, and more. • Borderline ECG, Inconclusive Apple Watch ECG, Inconclusive Fitbit ECG, Unclassified KardiaMobile EKG, WHOOP ECG, Garmin ECG, and all other Inconclusive ECGs analyzed within minutes, for clarity. • See irregular heartbeats like PAC and PVC on your ECG, analyzed by an expert ECG reader. • See your PR Interval, QRS Interval, and QTc Interval on your ECG, also analyzed by an expert EKG reader. • Get more from Qaly technician interpretations than your typical ECG analyzer app or HRV tracker: Qaly is the only ECG interpretation app where human experts provide professional analysis of your heart readings within minutes. • Share Qaly reports with your doctor, cardiologist, or electrophysiologist. ---- The Qaly app displays ECG data by integrating with the Health app. This is not available on the iPad.

App Purpose BIDSleep is a wellness app that helps users collect heart rate, blood oxygen (SpO₂), motion, and optional sleep stage data during rest or overnight sessions. It is designed solely for personal data logging and self-monitoring purposes. Use of HKWorkoutSession To enable higher-frequency physiological data collection (e.g., heart rate approximately every 5 seconds), BIDSleep uses HKWorkoutSession with the .mindAndBody activity type. This is required because alternative background methods like WKExtendedRuntimeSession do not allow sufficient sampling rates. No Analysis or Interpretation BIDSleep does not perform any health analysis, sleep scoring, or diagnostic interpretation. It simply facilitates the collection and optional export of raw physiological data from the Apple Watch and HealthKit for the user’s personal reference. Privacy All collected data remains securely stored on the user’s device and is never transmitted, analyzed, or shared without the user’s explicit consent. Disclaimer BIDSleep is not a medical device and does not provide any health diagnostics, treatment recommendations, or clinical functionality. It is intended only for general wellness and self-tracking use.
