---- Contraction Timer (Labor Tracker, pregnancy) ---

This contraction time has been designed for mothers facing childbirth to time the contractions easily. 
Focus was put on exposing the contraction cycle (contraction period + intervals) which is considered to be the most important information when timing contractions. 
If you have any additional suggestions or inquiries, please leave a message. 

[Main features]
1. Displays the contraction cycle (contraction period + intervals) by measuring the contraction period and intervals.
2. Displays the result of contractions in a graph or list.
3. In case the average of 3 contraction cycles is within 10 minutes, “Prepare for hospitalization” message will be displayed and in case it is within 5 minutes, “Actual contractions” message will be displayed.
4. The contraction records measured previously can be checked through the menu.
5. Provides classical music to relieve tension.
6. Provides a list of things to prepare for childbirth (checklist).

 [How to use] It’s quite simple~
1. Once the contractions begin, press the “Contraction start” button
2. Once the contractions stops, click the “Contraction end” button
3. Once the contractions begin again, repeat No. 1~2 for use.
4. If you press the “Reset” button, the measurements will be initialized and will automatically be saved in the History menu. (The existing measurements can be checked in the History menu.)

[How to read the graph]
1. If the Graph icon is pressed when there is a record of contraction measurements, a graph will be indicated.
2. The red bar in the graph refers to the contraction period.
3. The green bar in the graph refers to intervals.
4. The bar with the combination of the red and green refers to the cycle.
5. The red horizontal line indicated in the graph refers to “Actual contractions”.

### 5/5 — 감사합니당!

*2021-03-25, version 1.4*

안녕하십니까? 대구대학교 간호학과 김현진 학생입니다. 출산 관련 앱에 대한 조사 과제가 있어 진통측정 관련 앱 중에는 기능이 제일 다양하고 산모에게 필요한 기능만 모여있어 이 앱을 선정하게 되었습니다.
▶️ 이 앱을 사용한 결과 버튼으로 간단하게 진통 측정을 하며 3회 평균 진통 주기를 통해 진진통, 가진통을 구별하여 병원에 가야 한다는 알림이 뜨는 것도 산모에게 정말 도움이 되리라 생각하였습니다. 또한 클래식 음악 및 출산 준비물 체크리스트가 있어 산모의 안정을 꾀할 수 있는 부분도 장점으로 다가왔습니다. ▶️ 다만 저희가 어느 기간 동안 사용하다 보니 진통의 강도 또한 진통측정을 하면 좀 더 유용하지 않을까 생각이 들었고 진진통, 가진통을 구별하는 방법에 대한 자세한 설명이 추가되었으면 좋을 것 같습니다. 또한 앱을 사용하면서 자주 튕기는 현상이 있어 필요한 순간에 막상 활용을 못 하는 경우도 생길 수 있을 것 같습니다. 그리고 음악재생 시 종료 버튼이 인식이 안 돼서 앱 자체를 꺼서 종료를 시켜야 하는 경우도 가끔 있었습니다.
🤍 개발자님 산모들을 위하여 이러한 앱을 개발해주셔서 정말 감사드립니다. 덕분에 많은 산모가 도움을 받고 있을 겁니다. 앞으로도 많은 발전 기대합니다. 감사합니다.
