Always-On Display 3.0 & Tap Actions Always-On Display 3.0: glanceable display shaped around the camera cutout, per-element size (Hidden through Hero), presets (Minimal, Balanced, Battery Focus, Timer Focus, OLED Minimal), and a live device-preview customizer.Tap Actions: program an NFC sticker to log, open, or measure a tracker in one tap. The tag holds only an anonymous random code. Free keeps one active; Premium unlocks unlimited tags and camera-measurement actions.Reliability NFC Tap Action logs refresh the home screen, total and timer on return to the app. Replacing a lost or damaged NFC tag revokes the old tag; configuration and history are preserved. Includes everything from 7.1.3; additive database v28, in-place upgrade preserves all data.
Released 3 September 2026 · Build 102 · Android 8.0+ (API 26)

Notification, widget, detailed, retroactive, and NFC paths respect the same rules. Additive database v28 upgrade preserves existing data.
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.
