Released 3 September 2026 · Build 101 · Android 8.0+ (API 26)
Smarter tracking & fast entry Built-in vector covers: 32 crisp Material icons across medication, nutrition, routine and general categories.Long-press fast entry: quick access to recent amounts, next log value and detailed logging directly from the log button.Recent Values: adaptive latest, previous, and delta comparison with compact summary stats on expanded cards.Per-tracker accents: customizable high-contrast color palettes for personal tracker identity.One consolidated Edit tracker: rename in place, customize accent, and manage cover with a live preview. Smart Reminders keep learning even when timing varies — adaptive rhythm with honest confidence. Smart Insights adds time-of-day tendency analysis. Privacy & reliability PIN-protected hidden trackers: hide sensitive trackers from Home, AOD, and widgets with full restore in Settings › Privacy › Hidden Logs.Orientation recreation stability: screen rotation preserves active state without resetting destination. Resetting the privacy PIN no longer deletes hidden logs — "Remove PIN" keeps them, with a separate explicit delete and a Forgot-PIN recovery. Encrypted Backup excludes hidden entries. No database schema change; in-place Pixel 7 upgrade from 7.1.1 preserved all records and settings intact.
Released 2 September 2026 · Build 99 · Android 8.0+ (API 26)
History & Insights Explore logging history well beyond the previous 24-hour focus: Today, Yesterday, 7-day, 30-day and all-time. Calendar navigation to any past date, with that day's total, count and individual logs. Daily totals, logging frequency, 7-day and 30-day averages, previous-period comparison, and an adaptive logs-per-day chart. Add backfilled entries for a real past date and time; hide individual entries behind a private PIN in Settings › Privacy. Reliability Today and Yesterday use correct local calendar-day boundaries. Database upgrades to v27 with no data rewrite; in-place Pixel 7 upgrade preserved every protected record and setting checked by the release probe.
Released 2 September 2026 · Build 98 · Android 8.0+ (API 26)
What's New Semantic system haptics and reduced-motion-safe interaction feedback. Faster logging, stronger AOD/landscape layouts, NFC workflows, reminders, cover media, and durable PulseTrace transfers. Reliability Signed in-place Pixel 7 upgrade preserved every protected record and setting checked by the release probe.
Released 1 September 2026 · Build 96 · Android 8.0+ (API 26)
What's New Smart Reminder status now shows learning progress, confidence, expected window, armed time, and blockers. A concise details view explains the local prediction and recent scheduling activity. Reliability Robust local prediction rejects tiny accidental intervals and resists large outliers. New logs and history edits replace stale one-shot reminders centrally.
