What is Reddit's opinion of Contraction Timer?

From 3.5 billion Reddit comments

Mild contractions, the ones that are 15-20 minutes apart, can fill a period anywhere from 8 to 12 hours on average. This is early labor and you aren't rushing to the hospital yet. You have some time to get home at this point. (I personally wouldn't use up the whole 8-12 hours to get home, but I also wouldn't stress as I am on my way.)

When contractions are 3-5 minutes apart and lasting 45-60 seconds, you are in active labor and should get to the hospital. Active labor can last 3-5 hours, so don't drive crazy now, but do drive to the hospital.

Transition phase is last. Contractions are 60-90 seconds long with no more than 2 minutes in between. You should be at the hospital by now.

Disclaimer that no two births are exactly the same, and your wife may slip between these phases more quickly than average. Get a contraction timer to take some of the guesswork out of things.
