## What is Contraction Timer?

Simple and User-Friendly Contraction Timer App
Easily track contractions with a simple tap of a button. All data is securely stored within the app, eliminating the need for manual note-taking.

Tap the "START" button when you think contractions have begun. 
Tap the "STOP" button when you believe the contractions have subsided.

With just these simple actions, the app automatically calculates and records the start date and time of contractions, the interval between contractions, and the duration of each contraction.

In case of any entry errors, you can easily delete unwanted data by swiping left on the entry you wish to remove.
For bulk deletion of multiple entries, simply press the "Edit" button on the "History" screen.
