gReact je mobilna aplikacija koja je namenjena gradjanima koji žive na teritoriji Republike Srbije putem koje mogu dostavljati informacije i zahteve za rešavanje ekoloških problema koji su prisutni na lokalu. Gradjani putem aplikacije direktno prijavljuju sve ekološke probleme Operativnom centru Ministarstva za zaštitu životne sredine. Putem aplikacije se dalje može pratiti status realizacije prijavljenog problema. Kroz mobilnu aplikaciju gradjani će dobijati i važna upozorenja o vremenski kritičnim prirodnim i komunalnim dešavanjima koja su od značaja za sigurnost samih gradjana i imovine, odnosno za očivanje životne sredine (npr. Upozorenja o nepovoljnim meteorološkim uslovima, požarima, poplavama, saobraćajnim nezgodama koje uključuju vozila za prevoz opasnih materija…). Registrovani korisnici mobilne aplikacije mogu da dobijaju aktuelne ekološke i komunalne informacije koje tematski odgovaraju profilu korisnika ili su selektovane u odnosu na trenutnu lokaciju korisnika (npr. Vremenska prognoza, kvalitet vazduha, vodostaj, mape sa naznačenim novootvorenim mestima za odlaganje smeća ili opasnog materijala..)

Walk & Learn is a location-based cultural app that guides users through key sites connected to Jewish heritage in Belgrade. By following curated walking routes across the city, users discover historically significant buildings, monuments, and urban spaces that tell the story of the Jewish community and its lasting cultural impact. At each location, the app unlocks additional content through XR (extended reality), allowing users to scan buildings or monuments to access layered digital narratives. These may include historical insights, archival visuals, spatial reconstructions, and interpretative storytelling that enrich the on-site experience. Blending physical exploration with digital interpretation, Walk & Learn offers an engaging way to learn about Belgrade’s Jewish heritage directly in the places where history unfolded.
