Gran aplicación sobre todo para entornos electrónicos, aunque para la vida diaria, es un poco compleja de usar, sobre todo si no conoces los diferentes componentes o no sabes su objetivo final, como sugerencia yo pondría una Barra de busqueda para ir al grano, si necesitas información sobre telecomunicaciones... vas al aparatado de radiocomunicaciones, si necesitas información sobre SMD, que te lleve directamente a donde necesitas...

Понятное и приятное приложение, с хорошим инструментарием и отсутствием рекламы. Платные функции не навязывает, хочется отметить что PRO версия стоит всего 2$. Автору спасибо за человеческое отношение к пользователям)

Years later it's been useful, and I'm unsure if it's just me, but I don't see an option to have a "favorites" list for quick access
