What's New in Nerva
1.4.0
August 3, 2026
Nine sounds to listen to. Rain, ocean, forest, stream, fire, night, singing bowls, wind and noise. Press play, set the phone down, and let one run for up to ninety minutes. Controls on the lock screen. Start a sound, lock your phone, and pause or resume without unlocking it. A player that follows you. The mini-player now stays with you across every screen, so whatever is playing is always one tap away. Also in this update: a fix for a rare crash when moving between tabs mid-session, and the usual quiet polish. Nerva stays free, with every technique included. We read every email at nerva@qvisa.eu.
