What's New in THEONE Vault

September 29, 2026
Distance, live. When you both switch it on and allow Always, the kilometres on your widget move as you do, even when THEONE is closed. Your position is rounded to about a kilometre before it leaves your phone, your partner only ever sees the number, and either of you can switch it off. Never a map. One line a night. Every night now asks the same thing: what do you want to keep from today?
