none, all you need to know is.. kapag ang contraction mo ay tumatagal ng 1min. to 90 seconds at 5mins. interval you're in active labor. gumamit ka ng orasan, timer/stop watch yan lang wala ng app.
Type lang po kayo sa app store contractions monitor madami po available. Gamit ko is “contractions”
Nope, if mag monitor ng contractions stopwatch gamit po.m
