Contraction Calculator

Jan 07 - v1.1 released
This release supports both light and dark themes with accent colors. The darker theme helps save battery life on your Windows phone.

This release also provides a much tighter integration with Facebook.

Contraction Calculator is available in two flavors, a free Windows® Phone application (available for download from Zune® Marketplace or from your device by searching for Contraction Calculator in Marketplace).

We also offer this free online tool with a subset of feature that will help you monitor contractions even if you don't have the app installed.

Click on the Start button when Contraction begins. Click on it again when Contraction stops.
