Review momentum
73/100
faster than 88% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About Have a safe delivery
[ Have a safe delivery - Contraction cycle timer ]
The application that was made by a developer who has an labor experience!
Discarded all the unnecessary functions and has intuitive UI that you can check "contraction cycle" only!
You can simply check when to go to the hospital by recording your contraction cycle with only one button!
Wish everyone would have a safe delivery :D
**There is no ads except the ad bar below of main screen.
We’ll never give you any inconvenience of getting the pop-up advertisements while you are suffering from the contraction!
[ How to use ]
1. When the contraction starts, touch the "contraction started" button on the right bottom side of the screen.
2. When the contraction stops, touch the "contraction stopped" button and status will turn into "relax" mode.
3. If you have recorded incorrectly, touch and slide the record to the left and it will be deleted.
4. If you like to erase the whole data, touch the arrow button (initialization button) on the right upper side of the screen.
5. When the contraction cycle gets less than 5 minutes the alarm will go off, head to the hospital!
Tip. If you get confused with True labor contraction and Braxton Hicks contraction, please refer to the text below on the screen, it will help you :)
※ Always consult your doctor to orient yourself in terms of contraction frequency and duration. This app is not a medical device and our recomendations are based on standard indicators. Your labor may occur differently. Therefore, do not rely exclusively on our app. If the duration and frequency of contractions do not yet correspond to the necessary indicators but labor pains become unbearable, or if your water breaks or significant bleeding occurs, it is better to go to the hospital as soon as possible.
