Meditation gadgets

A curated guide to devices that can support your practice — we don’t sell them ourselves. The buttons open a real Amazon.es search for the product; there’s no active affiliate link yet, so it currently earns no commission. None of these devices is a medical device, replaces a professional’s evaluation, or guarantees a result.

Neurotech and biofeedback

  • Muse S / Muse 2from ~$295 + optional subscription

    A headband with EEG sensors that translates your brain activity into sound — softer rain the calmer your mind gets — giving real-time feedback during meditation. Muse S adds sleep tracking.

    Useful if you struggle to know whether you’re “doing it right” when meditating: the audio feedback replaces subjective guesswork with an objective signal, though it isn’t a medical device and isn’t clinically precise.

  • Apollo Neurofrom ~$349 + annual membership

    A wrist or ankle wearable that emits gentle vibrations (“SmartVibes”) designed to signal the nervous system it can relax, with different modes for sleep, focus, or calm.

    Complements the generator’s paced breathing: while the script guides your breath, the device adds a second sensory channel (touch) reinforcing the same calm signal.

  • Sensatefrom ~$269

    A device you place on your sternum that emits infrasound to stimulate the vagus nerve, paired with an app of guided relaxation sessions.

    Built specifically for the physiological relaxation response — the same goal techniques like coherence breathing or the physiological sigh pursue in the generator, through a different physical channel.

  • Core by Hypericefrom ~$159

    A meditation sphere held in both hands, with heart-rate sensors and haptic vibration synced to guided sessions in its app.

    Constant physical contact through the hands can help keep attention anchored to the body, a principle similar to what the body-scan technique uses.

Wellness and sleep wearables

  • Oura Ring 4from ~$349 + monthly subscription

    A smart ring that tracks sleep, recovery, and a daily stress indicator (“Daytime Stress”), with meditations and sleep stories built into its app.

    If you generate a session for “sleep after an anxious day”, Oura can objectively confirm whether you actually slept better than previous nights — closing the loop on measuring the outcome, not just the feeling.

  • WHOOP 5.0from ~$199/year (device included)

    A screenless wrist band focused on recovery, with a real-time stress monitor and built-in guided breathing exercises.

    Its real-time stress monitor can flag the exact moment of the day when a regulation session would have the most impact, instead of generating one blind.

  • Garmin (Body Battery)from ~$199, depending on model

    Several Garmin watches include “Body Battery”, a 0-100 indicator of available energy based on heart rate variability, sleep, and stress — no subscription required.

    With no monthly fee, it’s a simple way to know whether an activating session (focus) or a calming one suits you that day, based on your body rather than the clock alone.

  • Fitbit Sense 2from ~$199

    A smartwatch with an electrodermal activity (EDA) sensor to detect physical signs of stress, plus guided mindfulness sessions in the app.

    The EDA sensor can flag rising activation before you’re consciously aware of it — a use similar to the body-anchoring the body scan teaches, but measured rather than felt.

Sleep and relaxation devices

  • Dodowfrom ~$55

    A light metronome projected onto the ceiling: a circle of light that expands and contracts at a slowing pace to guide your breathing into sleep, no screen or app required.

    It does the same thing as the generator’s breathing tools — setting a visual pace — but passively, with no need to look at a screen right before sleep.

  • Somnox 2from ~$600

    A pillow-shaped robot that “breathes” — expanding and contracting — so you can hold it and let your own breathing gradually sync with its rhythm.

    A physical alternative to following a breathing pace with just voice or a timer — useful for people who relax more through touch than through a visual or audio cue.

  • Hatch Restore 2from ~$169

    Combines a simulated sunrise light, a sound machine, and a library of meditations and sleep stories in a single bedside device.

    Covers the whole bedtime routine in one device instead of switching between several different apps — useful alongside a generated session for disconnecting from your phone before bed.

  • Morphéefrom ~€80

    A screenless physical box with 200+ guided sessions you select by turning three dials — breathing, body, and visualization, across different lengths.

    Built for people who want a guided meditation with no screen involved at all — something a digital generator like this one can’t offer by definition. They complement each other rather than compete.

Breathing trainers

  • Moonbirdfrom ~$150

    A hand-held, egg-shaped breathing coach that physically expands and contracts to set the pace of your inhale and exhale.

    Translates into a physical object exactly what the generator’s breathing tools do (box breathing, 4-7-8, coherence) — useful for anyone who’d rather feel the pace in their hand than watch it on a screen.

  • Komuso Shiftfrom ~$79

    A pendant with a small mouthpiece that forces your exhale to be longer and more controlled than your inhale — the same principle as the physiological sigh, as a discreet all-day accessory.

    Extends the generator’s physiological-sigh principle to any moment of the day, no need to pull out your phone or close your eyes — useful during an argument, in traffic, or before a meeting.

Traditional accessories

  • Zafu / zabuton$25-60 for the set

    The classic set for sitting on the floor with an upright back with no strain: a round cushion (zafu) on a flat base (zabuton) that protects the knees and ankles.

    A stable, pain-free posture sustains a longer session better than an uncomfortable chair or the bare floor — the physical foundation for any of the library’s seated techniques.

  • Mala beads$10-40

    A traditional bracelet or necklace of 108 beads, designed to count repetitions of a mantra or a breath without needing to watch a clock or a screen.

    Fits directly with the library’s mantra-meditation technique: each bead marks one repetition, so attention stays on the word instead of on mentally keeping count.

  • Cuencos tibetanos$20-150

    Metal or quartz bowls that, when rubbed or gently struck, produce a sustained tone traditionally used to mark the start and end of a session.

    The sound can replace a digital chime to mark the start and end of any session, including the meditation timer with bells from the breathing engine.

  • Manta de peso$40-120

    A blanket evenly filled to add gentle, constant weight across the body, using deep-pressure input to support relaxation before sleep.

    The constant pressure can reinforce the “heavy, anchored body” feeling techniques like the body scan aim for at the end of the day.
