Novelty and fun that is stripped away in 30 days
What a powerful device, albeit with a terrible flaw. This is a clever and easy way to quickly produce a lead 1 ECG tracing. I got a kick out of using this as a 3rd year medical student.
However once one month has passed, your iPhone's App (the interface with the device) strips away all features except recording a tracing/ECG (yes, you can no longer review or save your tracings).
If you'd like those features back, you will need to pay $10.00 per month.
