I’m not seeing an issue when testing. Can you provide additional information? ### 3/5 — Simple Interface + Valuable App *2018-06-27* Intensity of contractions shown through sad face icons is 100% the wrong message to send to mothers during labor. Birth is natural, beautiful process and women shouldn’t be rating their experiences with various sad faces. The app is simple, easy to use and attractive. Valuable to use during labor. ### 5/5 — Elegant and useful *2018-04-06* Recommended by our coach, this app is clean and worth the investment. Easy to use and no ads. ### 3/5 — Hospital reminders *2017-06-22* I'm a midwife, and I've been using this app to time contractions at homebirths for years, while I appreciate the option for the app to tell the user when to go to the hospital I don't like the update doesn't allow you to turn it off and the reminders come after each contraction. I'd like the option to not use that feature returned to the app. **Developer response:** Thanks for your feedback! As of the latest release (version 4.0.3) you can now control whether or not the Hospital Alert automatically appears. ### 4/5 — Great needs a feature *2015-08-09* Great and easy for what it does. Needs a delete all on the history screen. For intermittent tracking it's a nuisance to delete each entry one by one compare to how simple and easy to use the rest of the app is. ### 5/5 — BEST way to track contractions *2015-05-10* 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 don't need this one any longer. ### 3/5 — Great App *2013-09-10, version 3.0.2* Easy to use app and gave us just the information we need to get to the hospital on time. Would have like to be able to manually add in contractions for time spent away from phone such as when I was resting/showering. Apart from that, pretty good. ### 5/5 — Thank God for this app! *2013-01-10, version 3.0.2* Great app! I was stressing about not knowing how to time my contractions and stumbled across this! Thank god I did...with a very quick labour I made it to the hospital in the nick of time because of this app! The midwives were very impressed with the app! They couldn't believe I could give them all the details of my contractions with such accuracy! Thanks again! ### 3/5 — update not so great *2012-10-24, version 3.0* This was a great app, but now the history graph/chart is gone. A visual display of data is important for stressed parents to be. Please bring it back. ## Frequently asked questions about Contraction Master ### What does Contraction Master do?
