Λελεδόμετρο Στρατού is an Android-based military service calculator developed by Giannis Alevizakis. It is a free app available on the Google Play Store that allows users to calculate their total military service days, days served, and days remaining until discharge. The app also enables users to store their services and leaves, view them in a calendar format, and track their military service and leaves through graphs.

In addition to these features, the app allows users to record their incarcerations, curfews, and other important information such as their weapon number, sword number, and other significant events during their military service. The app also displays the insignia of all the officers of the Greek Army, Navy, Air Force, Police, Fire Brigade, and Coast Guard. Users can view the correlations between officers in various units and weapons, such as tanks, and select three different color themes by choosing one of the three main branches (Army, Navy, and Air Force).
