The CalmSky Pebble helps your body shift into its "rest and calm" mode. Gentle pulses through the center of your palm — most people feel a subtle steadying sensation within minutes. It works best paired with the Flight Guide and used consistently across the flight arc: before, during, and after.
How do I use the Pebble?
Hold it in your palm so the contacts sit against the center. Turn it on and choose your intensity — you can adjust anywhere from 0.2A to 1.3A. Sessions are recommended at around 15 minutes. Use it at the gate, during takeoff, in the seat, or whenever tension rises. It's silent, so no one around you will know it's on.
What's in the Flight Guide?
The Flight Guide is written by a commercial pilot. It covers the days before your flight, what's actually happening up there, what's happening in your body, and a plan for the flight itself. Included with the Bundle. Delivered as an instant PDF you can read on any device.
What's the technology behind the Pebble?
Gentle microcurrent pulses through the center of your palm — low-level electrical pulses, well below the levels that stimulate muscles. Adjustable intensity, silent operation, no consumables.
Is it safe to use? Are there any contraindications?
The Pebble is not suitable for people with a pacemaker or other implanted electrical device, during pregnancy, or for people with active cancer or epilepsy. If you're unsure, please ask your doctor before use. The CalmSky Pebble is a wellness product, not a medical device — it's not intended to diagnose, treat, cure, or prevent any disease.
Can I bring it on a plane? Through TSA?
Yes. The Pebble is palm-sized and carry-on friendly. It's TSA-compliant and passes through security without issue. You can also use it during boarding, takeoff, and in your seat.
Can I buy the Pebble or the Flight Guide separately?
Yes. You can buy just the Pebble, just the Flight Guide, or both together as a Bundle. Most customers get the Bundle — the two are designed to work together.
What's your return policy?
30-day money-back guarantee on the Pebble. Send it back within 30 days of receipt for a full refund. The Flight Guide, once delivered, is non-refundable — it's a digital product. Not satisfied? Contact us at support@calmsky-shop.com with your order number and we'll take care of it.
How long does the battery last?
The Pebble has 20 hours of use on a single charge. It charges via USB. A full charge takes about two hours.
Is there a subscription or ongoing cost?
No. One-time purchase, no consumables, no subscriptions, no app fees.
