Sign in with your work account to get started. Small habits, real change. A few notes: - Release notes lead with the new multi-KPI reveal (the visible feature) and honestly name the bug fix without over-explaining. - The waste/time/health lines are hedged with "where your company tracks them" since those KPIs are per-customer toggles - most tenants only have money and CO₂ on, so you don't want to promise metrics a given user won't see. - Want me to trim the release notes to a shorter single-paragraph version, or draft a Google Play "What's New" variant (500-char limit) to match? --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
