## What is Contraction Monitor?

Contraction Monitor is designed for pregnancy mums to track contractions. 

Regular contraction is an importance sign of labor, when that big time is approaching, duration of contraction becomes longer and stronger, frequency becomes shorter. And contractions will show their laws when true labor is coming, so keep tracking contractions will help you distinguish true labor from ‘false’ labor. Graph of contraction duration and frequency makes it easy for you to see the tendency of contractions.

⁃ Share your contraction data with your doctor or friends by email. 
⁃ Continue contraction where you left off in the condition that you make a call or play other apps while logging contraction. 
⁃ Calculate your delivery due date, show days remaining to your due date and days passed from your last menstrual period. 
⁃ Contact module for you to add your labor contacts, you can call them conveniently by one touch if your baby is coming when you are logging contractions. 
⁃ Support edit function for contraction logs.

### 5/5 — Great app

*2022-01-21, version 6.0*

Super easy to use and I love that it connects to my watch.

### 5/5 — Easy to use

*2018-01-02, version 3.4*

It’s easy to use. Very clean and simple interface, with graphs and other things tucked away to reduce the clutter.

Unlike other users, I read the developers description of the app which mentions it is limited to 20 contractions before requiring an upgrade to the full version.

You can migrate your data from the free version to the full version with a simple tap in settings.

At first use, I thought there should be a “reset” data option on the main screen as I was playing around with the app. I then imagined the frustration of a mother in labour accidentally resetting her data.

I think the app is great how it is.

### 3/5 — Good app but ads interrupt at very bad times

*2017-04-07, version 3.3*

This app works very well and we used it in preparation of both our children.  But I will say one thing: the placement of occasional video ads is INFURIATING. I understand banner ads and small things to pay for a free-ish version, but if you are timing contractions in active labor, you DON'T want to watch a video before proceeding to the next screen.

Designers: Good job on the product and interface.  But get a better ad model.  Seriously.  That's a major UX failure.

### 5/5 — Handy

*2016-10-23, version 3.2*

This free app is super easy to use and helpful for timing contractions. It doesn't just average the time in between contractions, but keeps the real data so you can see your progression.

### 5/5 — recommended!

*2016-08-18, version 3.2*

easy to use and very helpful during my labour

### 5/5 — 구매목록 삭제

### 1/5 — Ugh

*2016-01-12, version 3.1.1*

Just promotes paid version

### 5/5 — Great app during labour

*2015-11-15, version 3.1.1*

Perfect to record and look back at data during labour. Easy to use

### 2/5 — Flawed and gives inaccurate data

*2015-10-01, version 3.1.1*

Very hard to get accurate data, since it averages your frequency. It makes inconsistent BH contractions seem like real ones. Information is not set up in a helpful or easy to read way. The charts are very hard to read and relevant info is hard to get ahold of.

### 1/5 — Horrible on Apple Watch

*2015-09-18, version 3.1.1*

Don't bother with this app if you plan on using it on your watch. It lags and doesn't allow you to start or stop timing accurately. Very frustrating when you're trying to time contractions!!
