SpeakMap gathers places such as doctors, notaries, auto services and on-call plumbers on one map, since in a new country people usually look for them through relocation chats and after six months half the answers become outdated. The service currently covers Belgrade and Novi Sad. Its main feature is not the map itself but the honesty of the “Russian is spoken here” label: anyone can press “Yes” or “No,” and trust in the label is calculated using the lower bound of a Wilson interval. The project was built with Kotlin, PostGIS and pixel graphics.
