Why do bin bags have a certain colour in Switzerland? How long is a "vignette" (motorway tax sticker) valid for? Which language is spoken at the southernmost tip of Switzerland? What does "simplified naturalisation" mean? The "together" app, developed by all of the SRG SSR’s business units (RSI, RTR, RTS, SRF and SWI), tackles questions from day-to-day life, provides answers and reveals other useful information. Its is based on the practical guide to Switzerland produced by SWI swissinfo.ch. The integration app currently comprises 10 topics with around 300 questions, background information and a news feed. The app is set to be expanded on an ongoing basis – and users can help one another with this by sending questions and images to the "together" team via an online form on the website.
