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. The published record does not sort them that neatly.

Apollo has four papers on PubMed with the device in the title, 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 ketamine study found no difference in anxiety, and none is about the vagus nerve.

Pulsetto is named in two studies in our research index. One is a 2026 lab study in healthy young adults: a single session at the neck, about nine people per group, during which systolic blood pressure fell and alpha brain-wave activity rose. The other used Pulsetto as a prop: football players were told it would help them recover while they received only sham stimulation, so the researchers could measure the placebo effect. Beyond those two, what Pulsetto 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. Apollo’s papers are evidence for Apollo’s vibration. Pulsetto’s rest mostly on 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 $239 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 $209 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.
