SMDCodeDroid is an Android application that helps circuit design engineers identify devices based on SMD-markings. The app provides brief characteristics of the device and allows users to browse or search its datasheet on various search engines. It is compatible with both mobiles and tablets.

The free version of the app has ads, but users can edit the application database by following the instructions in the 'Help' section. The developer, Maksim Bartosh, encourages users to send error reports, proposals, and observations for any issues they encounter, which will be promptly fixed. SMDCodeDroid is a handy tool for circuit design engineers who need quick and reliable identification of SMD-marked devices.
