This app is worth a lot more than $1.99. I changed the setting on my phone to not lock, and used this app frequently during the last two days of my pregnancy and labor. Also the perfect thing to use while in labor, but not hooked up to monitoring. All the features are absolutely wonderful, and better than anything else I attempted to use on a free contraction timing app. Plus I could email the report to my midwife and myself. Sad to delete the app now that baby is here. I never delete apps I love, though clearly I dont need this one any longer.
