Version 29The app is now named Quantum Breath.Changes & history
THIS VERSION

Quantum Breath

  • Consistent Quantum Breath branding across screens, translations and the page title.
  • Updated history export names, calendar reminders and audio playback metadata.

Previous versions

Version 28Softer background alternation
  • Replaced the black background with a slightly darker beige for gentler contrast.
  • Dark text and controls remain readable on both backgrounds.
Version 27History and schedule stability
  • Device history is retained when an offline query returns an empty or partial cache.
  • Prevent duplicate submissions and removed appointments reappearing after rapid actions.
  • Keep schedule data visible and acknowledge durable changes when the extra local cache cannot be written.
  • Restore default preferences on account changes when browser storage is blocked.
  • Show the final hold after exhalation in the history of four-phase sessions.
  • Slightly darker supporting text for better readability on light backgrounds.
  • Signing out of the demo also clears a previously active Google sign-in.
Version 26Mobile layout and vibration checks
  • Background timing bounds are 0.2 seconds shorter. Vibration keeps its original independent bounds.
  • Adapted controls, safe-area spacing and the effects menu for narrow and short mobile screens.
  • Added a vibration test with feedback when the browser does not support or allow it.
  • Check vibration from Begin/Continue gestures and stop it immediately on pause or when disabled.
Version 25New Firebase project
  • Added the new backend configuration for Google sign-in, history and schedule.
  • Accounts and sync use the new project once its corresponding services are enabled.
Version 24Independent installation
  • Removed all connection settings for the former Firebase project.
  • The local demo works independently until the new project is connected.
  • Separate project storage prevents automatic replay of former history and pending records.
  • Prepared access rules for each account’s own history and schedule.
Version 23Sign in with Google

  • A separate demo entry without entering credentials.
  • Messages for cancellation, blocked popups and connection errors.
Version 22Independent background and vibration
  • Reserved space for breathing instructions keeps longer hold text from shifting the layout.
  • The existing background alternates with black using independently chosen durations within each feeling’s limits.
  • Independent vibration and silent intervals on supported devices.
  • Separate saved switches in preferences and during the session.
  • Pausing stops both effects and restores the original background.
Version 21Optional second hold
  • A new setting enables the In · Hold · Out · Hold cycle.
  • The second hold uses the cycle's existing hold duration without changing the original timings or randomness.
  • The green circle now reaches the outer boundary while breathing in for clearer visual guidance.
Version 20Clear disabled audio state
  • The card, percentage and slider turn grey when a sound is disabled.
  • A disabled slider cannot be moved until the sound is enabled again.
  • The saved volume is preserved and restored when the sound is enabled again.
Version 19Cleaner settings screen
  • Removed the separate Preview voice and Preview rain section.
  • All session audio is now controlled only through the unified volume settings.
  • Voice, bass, emotion frequency and rain behavior during sessions remains unchanged.
Version 18Unified volume settings
  • Four consistent volume sliders for voice, bass, emotion frequency and rain.
  • Bass volume can now be raised independently without changing its frequency.
  • All four enable switches are grouped beside their matching volume controls.
  • Emotion frequencies, the In → Hold → Out voice and breathing timings remain unchanged.
Version 17Session frequencies and bass
  • Restores the original 174, 285, 396, 417, 528 and 852 Hz feeling mappings.
  • The selected frequency and bass start, pause and stop with the session.
  • Independent settings switches can turn the frequency or bass off.
  • The In → Hold → Out voice and existing breathing timings remain unchanged.
Version 16Breath hold added

  • New Hold cue, a still circle during the hold, and Greek and English labels.
  • Hold duration is included in session history and exports.
  • The existing random generator is retained. Phases include time for each complete spoken cue.
Version 15Mobile usability improvements
  • Larger calendar buttons and the device date picker on narrow screens.
  • More reliable screen wake management and return from pause.
  • Prevent session startup when the page is interrupted while audio is preparing.
  • Breathing timing and randomness are unchanged. Locked-screen playback remains browser dependent.
Version 14Sync stability
  • A schedule sync failure no longer blocks session saves.
  • History updates after successful saves even when other changes remain pending.
  • Pending-storage read errors remain visible.
Version 13Reliable saves and shared foundations
  • Sessions awaiting sync remain on the device and retry using the same identifier.
  • Schedule connects to the account with visible sync status.
  • Previously cached history remains available when loading fails.

Version 8Separate accounts and audio controls
  • Separate audio preferences for each account in this browser.
  • Discard stale history responses and clear active sessions when accounts change.
  • Media controls and background playback request, with pause on audio interruption or timing stalls. Locked-screen playback requires device testing.

Version 7Detailed history and more control
  • Generated timings and session events recorded for each newly saved session.
  • History filters, check-in answers, cycle timings and CSV / JSON exports.
