A lie detector, or polygraph, measures physiological responses such as heart rate, blood pressure, and respiration while a person answers questions. It is believed that deceptive answers may trigger noticeable changes in these responses. However, the accuracy and reliability of lie detectors are widely debated, as various factors can influence results, including anxiety and individual differences, making them more indicative of stress than truthfulness. Consequently, polygraph results are not universally accepted as definitive proof of lying.
No, you cannot get a lie detector test done on someone you think is cheating as it is considered an invasion of privacy. If you have good clues that this person is cheating then you can see a pattern as to what evenings they go out and either follow them with a friend in a car they do not recognize or pay a private detective for a weekend to get the proof you need.
No. Not even slightly possible. Lie detector results are not proof either though. If your s/o is insisting on you taking a lie detector test to prove you're not sleeping around then take my advice and ditch the ho/a55hole ;-)

yes people can it actually detects how nervous u are not really a lie detector
A lie detector test follows you pulse, if you are asked a question and your heart rate rises or falls then it will be a lie. If you can regulate your pulse you cannot be detected on a lie detector

AHH a lie detector ANSWER by Engl1sh: A perfessional typically uses the term 'polygraph' test.
Apple's app reacts on the basis of voice stress analysis. A traditional lie detector reacts to changes in temperature and moisture of the skin that occur when you are knowingly lying. Their weak point is that if someone is an 'easy' lier by nature, has started believing his own lies or mistakenly thinks that what he tells is the truth, the lie detector will not react. Also, if you have the time it is possible to 'train' for questions where you may want to lie, so the lie detector doesn't notice a skin or voice stress change. On the other hand very nervous people may cause 'false positives' even when they are not lying. It's why almost everywhere, lie detector results are no longer accepted as 'proof' by Courts. Apple sell its app just as fun and games, and rightly so.
Lie detector results are not admissible in the courts in the United States. On rare occasions, a defense attorney and/or a district attorney may conduct a lie detector test if there are doubts about a case.
very

Nope.
