PROS: Simple and easy to use. No in-app purchases from what I can tell. No obnoxious adds (just a few "download our affiliate app" banners and a "rate us" banner). CONS: wish it would prompt you to rate the intensity of each contraction after stopping the timer instead of having to go in and manually set it. Also, when editing settings for a contraction, the delete button is big and at the bottom but the save button is small and at the top. I almost pushed the delete button the first few times because it is more prominent.
