There were two free ones when I found these (back in May, I think?) but there are a few more now. The ones I tried are "Stage 1" and "Contraction Timer Deluxe"
Overall, they both function about the same - once you open the app, there is a button to START timing a contraction, and then you press the STOP or END button when the contraction is over. Both create a history and a chart or graph duration of the contraction AND the interval in between.

Overall, I like the look of the summary chart on Stage 1 better than the one on Contraction Timer Deluxe, because the Stage 1 chart shows both duration AND interval on one chart. The Contraction Timer Deluxe only shows one at a time.

Other than that, they are both really easy to use, and they store all the information you will need for the hospital when checking in, or for your doctor/midwife. Also an awesome keepsake for the baby book! The iPad lets you take a screenshot to save as a picture, and of course you can email those pictures to any email address. (or post them on your blog! ha ha ha)
The Contraction Timer Deluxe has a feature that I haven't yet used, but can see the potential for needing/wanting it: when you press STOP at the end of a contraction, it gives you the option to add a note to the contraction record before saving it to the chart/graph:
Like, I don't know, noting if a contraction is suddenly way stronger (or way weaker?) than the ones before it? Or maybe note the exact time that your water broke?
Stage 1 has a feature I like, that you can set a background picture behind the 'focal point ticker' (which can be turned ON or OFF in the settings) However, I chose a picture of my hubby for this background, and the ticker looks disturbingly like the target inside a rifle scope.....I'll have to figure out a better background picture or just turn that feature off.

I am looking at one more free app, simply called "Labor and Contraction Timer" (or CTX Timer?) but have not really used it much yet.
I think I am most likely to use the Stage 1 timer, but all of these are WAY better than trying to write it on a notepad and figure out the duration between contractions, etc. Anything that simplifies labor is a plus in my book! Especially if it's FREE - my favorite four letter word.
