CarDSScan

CarDSScan delivers research-grade, on-device ECG analysis from the Cardiovascular Data Science (CarDS) Lab. Built for reliability and privacy, CarDSScan runs its machine-learning models entirely on your iPhone - no internet required and no cloud uploads.

Two ECG analysis engines

ECG-Vision ATTR: Capture or import clear photos of printed or screen-displayed ECGs for fast, fully on-device analysis.

ECG-GPT: A transformer-based ECG interpretation model designed for research-grade signal understanding. ECG-GPT runs locally on your device and may require approval for access.

Private by design
All inference happens locally on your device. ECG images and outputs stay with you unless you explicitly export them. Certain advanced models may be downloaded after approval.

Developed by CarDS Lab
Models are developed by the Cardiovascular Data Science (CarDS) Lab and have been evaluated across multi-center research datasets. CarDSScan is intended for research use only and is not a medical device.
