This is an app that functions as a Pomodoro timer and a timer-based sleep aid. When Norse Vikings crossed the sea, the rowers cried out in unison — "RO" (row / calm). Viking Ro is a focus-first audio timer that rides that ground-rumbling chant to carry you into the zone. Built for desk workers who can't concentrate to lo-fi, or who nod off in silence. TWO VOYAGE MODES • Interval (free): Departure → Cruise → Sprint (an imperceptible tempo lift in the final stretch) → Arrival, where the break fades to waves and birdsong. • Deep Work (in-app purchase): a flat, unchanging "RO!" rhythm — the Viking answer to a ticking clock — to hold 1–2 hours of uninterrupted focus.
