What’s new in Boop.

Added

• Battery pack telemetry: Band now displays live charge percentage when a WHOOP 5.0 or MG battery pack is attached, and Home indicates charging with a bolt icon.
• Automatic launch offload: Opening Boop or returning to the foreground automatically triggers an offload check when fresh banked history is ahead of the local frontier.

Improved

• Cold launch speed: Optimized cold launch responsiveness so the Home screen and cached Health snapshot become interactive in under two seconds.
• Bounded background work: Replaced the legacy 15-minute periodic background timer with event-driven BLE wakes and coalesced retry triggers to minimize energy impact.
• Pipeline serialization: Bounded pipeline execution so durable HealthKit exports run without stalling UI interactions.

Fixed

• Fixed an issue where manual pull-to-refresh could fail to start offload when returning from background.
• Resolved daily sleep duration calculations to total all sleep sessions correctly.

Added

• Strap compatibility: Full local Bluetooth offload support for WHOOP 5.0 and WHOOP MG hardware without a WHOOP cloud account or subscription.
• Apple Health export: Direct HealthKit writes for Heart Rate, Resting Heart Rate, Heart Rate Variability (SDNN), Steps, Sleep analysis, and Workouts.
• Liquid Glass UI: Native iOS interface featuring a Home Health snapshot, minute-by-minute Day Trace chart, Band strap detail view, and Settings.
• Onboarding & privacy: Local permission onboarding with history-trim acknowledgements and zero app telemetry or analytics.

Improved

• Strap auto-reconnect: Automatic bonding and reconnection when a paired strap comes within Bluetooth range.
• Offload auto-continue: Drains onboard strap memory in resilient chunks to survive jetsam or connection drops safely.

Added

• HealthKit writer safety: Added transaction boundaries and retry cursors to prevent duplicate or skipped Health writes.
• Onboarding state persistence: Saved health permission selections and history-trim disclaimers safely across app restarts.

Improved

• Bluetooth packet parsing: Hardened frame index checking during offload to prevent invalid frame crashes.
• Background BLE wakes: Improved background Bluetooth reconnection when iOS wakes the app for strap data.

Added

• Boop identity: Established app listing identity Boop: Strap to Health and local-first bridge architecture.
• Liquid Glass design system: Created custom BoopGlass UI components, glance cards, and status indicators.
• Support & disclosure site: Created the public web support site, methodology documentation, and AEO endpoints.

Added

• WHOOP 5.0 support: Read strap history over Bluetooth without a Boop account or cloud.
• Apple Health integration: Write heart rate, resting heart rate, and steps directly to HealthKit.
• On-device privacy: Zero app analytics, zero accounts, zero cloud servers—100% processing on your iPhone.
• History trimming: Optional strap memory cleanup after verified local save.
