iSdt, developed by RedDev GmbH, is an electronic reference for members of the Swiss Armed Forces that consolidates service knowledge for everyday use. It provides searchable reference material, branch-specific modules, and multimedia to keep service regulations and unit information accessible on a handheld device. The app targets recruits, active-duty soldiers, and association members who need quick, portable access to service data during training and deployment.

iSdt brings multiple field manuals into one portable companion

Consolidation is central: the app assembles more than 40 specialized modules that historically lived in separate paper manuals. Those modules include military abbreviations tied to regulationsandII, tactical symbols defined by regulation, and visual guides for grades and badges. For quick reference the interface groups reference types so users can consult doctrine, symbols, and identification details without carrying multiple books.

The app supports role-focused study and offline field use

iSdt provides specialist modules for defined branches, enabling role-specific preparation for tasks in Infantry, Pz/Art, Aero, Seelsorge, and other services. Many modules and downloaded regulations are accessible offline, which supports use during field exercises. The app also offers searchable WK-Daten by troop, school, and year, plus an emergency contact directory and advice for service-related difficulties, helping individuals prepare for both administrative and operational scenarios.

It functions as a reference tool rather than a training tracker

iSdt supplies reference content and multimedia unit galleries, but it does not include learner assessment, performance reports, or automated progress tracking; its value is rapid lookup and situational guidance rather than recording training outcomes. The app runs on Android devices from version 6.0 onward, and RedDev publishes it as a private initiative, which positions the tool as a practical study companion instead of an official training record.

Practical companion for individual study, not a substitute for official records

iSdt is a practical option for Swiss recruits and soldiers who need immediate, portable access to service knowledge during training and duty; expect it to support individual study and role preparation. Because it is a private initiative and lacks assessment features, use it alongside formal documentation and training logs rather than as a primary administrative record.
