What's New in STFU
1.0.8
September 14, 2026
Bedtime now counts the morning after — the hours you were locked, on your clock. A session through midnight stays locked. Instagram and the rest cannot sneak back in. Spend your daily muted-apps time and Chrome locks too, if you share with it. Friends week is sessions they started. Lifetime is labeled separately. Muted-apps time is clearer on Home.
