Doctor ECG guide & calculator App Comentários

I have no idea why this app was made? Doesn't work, won't take pictures when needed, says my angle is off. I tried to move my phone to the right angle still nothing. Waste of 5.00. Needs to be free.

Don't buy it doesn't work

the idea is excellent but do not waste your money in this

This app is terrible! Do not buy it!

Hard to used and doesn't work totally inaccurate-- faster to do it by hand with calipers

Not worth the 5 bucks. Doesn't work and is not accurate at all. Cheaper alternatives are available and less Complicated

Could not accurately measure anything
