Technical Aspects of Galaxy Watch App Development

on YouTube ↗30m

" summary

Galaxy Watch development targets Tizen 4.0 with new dotnet support, promises longer battery life (regular watch up to seven days) and a smartwatch market forecast of ~200 million devices by 2022. Apps run as standalone (Nest, GoPro Shutter, offline music playback) or companion (Uber), use the rotary bezel for navigation, widgets for real‑time updates, and watchfaces must keep always‑on pixels <15%. Location API auto‑selects GPS or phone, human activity monitor exposes sleep/HR sensors, and deployment uses Tizen Studio over Wi‑Fi.
