Of the 3 Ive tried, this is the best!

I tried two other contraction timer apps but they fell short. I really wanted one that would allow me to delete history (not just the most recent contraction). This app allows me to view my history and delete any contractions from the list I choose (like when I forget to hit stop and a contraction ends up looking way longer than it actually was - or if I decide it was a false contraction and it needs to be removed from my interval calculation.) Ive only used the lite version of this app and am happy so Im sure the paid version is even better.
