Pulsetto vs Apollo Neuro: electrical stimulation against vibration

Pulsetto is transcutaneous vagus nerve stimulation. It sits around the neck and delivers current to the nerve where it runs up either side, in sessions of four to twenty minutes.

Apollo Neuro is vibrotactile. It sits on the wrist or ankle and delivers patterned vibration to touch receptors in the skin. The company’s framing is that certain rhythms shift you toward a calmer autonomic state. There is no current and no nerve is being stimulated directly.

Apollo gets listed beside vagus nerve devices constantly, including in our own roundup, which is how most people arrive at this comparison assuming the two are interchangeable. They are not, and the research on one does not carry over to the other.

The assumption most buyers bring here is that the electrical device is the serious one and the vibration device is the gadget. On published research naming the product, that is backwards.

Apollo returns 17 records on a PubMed search for the device. Studies naming it appear in the American Journal of Medicine, the Journal of Rheumatology, JMIR mHealth and uHealth and the Journal of Psychiatric Research, covering wellbeing in medical students, fatigue in systemic sclerosis, sleep, and anxiety during ketamine assisted therapy. Several are small. The company has still done what almost nobody in this category does, which is put its own device into trials and get them published.

Pulsetto has no indexed publication naming it. What it has is a mechanism that sits inside a studied field, where meta-analyses of transcutaneous stimulation report improvements in insomnia and depression scores, graded low to very low quality by the reviewers themselves.

Those are two different kinds of credential. One is evidence for a product, the other is evidence for an approach. Our read of the tVNS literature sets out how much weight the second one carries.

This is the practical difference and for most people it decides it.

Apollo runs in the background. You put it on, pick a mode, and it works while you get on with your day. Nothing to schedule and nothing to sit through. The cost is the battery, which runs six to ten hours and needs charging daily, and the fact that you are wearing something continuously.

Pulsetto is a session. Four to twenty minutes, hands free, then you take it off. Nothing to wear the rest of the day and nothing to charge nightly, but you do have to remember to do it.

If you have abandoned wellness devices before, be honest about which failure mode is yours. People who forget to do things do better with continuous wear. People who dislike wearing things do better with sessions.

Pulsetto is $259 with free shipping on the offer our link reaches. The stimulation programs run on the free app tier, and the premium content library is a separate optional subscription. The other recurring cost is conductive gel.

Apollo is $448, listed as the wearable bundled with a SmartVibes AI membership and a sleep band. Its modes run through the app, so the membership is part of how the product is sold rather than an add on you can ignore.

The gap is $189 up front, in favour of Pulsetto.

Pick Pulsetto if you specifically want electrical stimulation of the vagus nerve, you want to spend less, or you would rather do a short session than wear something all day.

Pick Apollo if the format is the appeal, if you want the device in this category with the most published studies naming it, or if you already own an Oura Ring and want the integration.

Look further if you are buying on trial evidence for vagus nerve stimulation specifically. The only consumer device named in tVNS trial methods is the Parasym ear clip, sold as Nurosym in Europe and Nuropod in the US.
