2.3 12/16/2025
this update brings two new features: Achievements & Ventilation Timer.
- Achievements: Earn badges for your airing routine — from streaks and “Ice-Cold Airing” to marathon minutes. All neatly organized in the new Achievements tab.
- Linked Timer: Start a timer straight from the dashboard recommendation. The recommended duration is applied automatically, so you air exactly as long as it makes sense.
- Smart behavior: When everything is “in the green,” the Achievements tab won’t show a timer — instead you’ll see a friendly note that no airing is needed right now.
We also added some visual polish so everything looks consistent and clean.
