Version 2.1 adds Read Quality: a new report that checks signal confidence, capture length, waveform detail, rhythm context, and breathing-session context before a result becomes part of your wellness history. This update also adds clearer research citations, safer wellness wording, refreshed metadata, and new App Store screenshots.

This update sharpens the interface: the iPad layout now uses a centered, comfortable reading width instead of stretching edge to edge, plus small display fixes. iPhone is unchanged.

Pulselume 2.0 — a pro upgrade for watching your pulse and breathing it down, still 100% private and offline. • Coherence biofeedback: a live 0–100 relaxation read during breathing sessions (a wellness metric, not medical). • Respiratory rate from your pulse, shown live as a breaths-per-minute estimate. • Synthesized relaxation soundscapes (ocean, rain, warm drone) with phase-synced inhale/exhale tones — no downloads. • Three new breathing patterns: Resonant (6/min), Extended Exhale, and Triangle. • Multiple pulse-waveform visualizers (line, bars, ribbon, dots). • A wind-down reminder and a personal wellness-log PDF export. Pulselume is for relaxation and curiosity only — it is not a medical device and is not for diagnosis or treatment. No account, no network — everything stays on your device.

Your personal context, your own breathing pattern — and your streak. • Personal baseline — every result now shows how today's reading compares to your rolling 14-day average ("3 BPM below your usual"). A new Insights screen in History shows your baseline pulse, calm, and variability averages, personal bests, and recent trend direction. • Custom breathing pattern — build any inhale/hold/exhale/hold rhythm you want (1–20 s per phase) and run it as a full session with live pulse, just like the built-in techniques. Your pattern is saved and easy to edit. • Reading streak — see how many days in a row you've logged a reading, with milestones that mark when your 14-day baseline becomes reliable.

Two new breathing techniques. Notes. Export. And a plain-English guide to what your numbers mean. • Physiological Sigh — a double nasal inhale followed by a long, slow exhale. Research (Balban et al., 2023) shows this single breath pattern resets the nervous system faster than any other technique tested. • Sama Vritti 4-4 — a clean equal-rhythm anchor: four seconds in, four seconds out. Simple, consistent, easy to sustain. • Mood tags & notes — after saving, tag your reading with how you felt (Calm, Stressed, Tired, Energized, Anxious, Focused) or write a short free-text note. Your tags show in the history list. • Export — tap the share icon in History to export your readings as a CSV file for Numbers, Excel, or any spreadsheet. • "What does this mean?" — a new reference card on every result explains your BPM, calm score, and variability in plain language, including an authoritative resting heart-rate zone table with your reading highlighted.
