Read full descriptionHide full description
StethAid Lungs is an app to collect anonymised lung sounds of a study subject with suspected asthma. StethAid Lungs connects to the StethAid Bluetooth digital stethoscope and allows for streaming of data from the stethoscope. The lung sounds and the corresponding laboratory test results will be uploaded to a remote database for post-processing storage and reference. The app is password-protected, so only authorised users can use the app to capture and upload lung sounds. Only the study subject’s age and gender is stored, no other PHI data is stored in the remote database.

Verdict
The clearest difference is ads: StethAid Lungs at none against StetSAFE's shown. StetSAFE's advantage is update cadence (every 3 months vs every 7 months) and iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.
