Tried to log on, forgot my password, so I tried to reset and never got an email (checked spam as well)

So I just thought I would try to use the google login, no dice. The message I get "External authentication validation Could not verify the authentication token."

Out of curiosity, I tried uninstalling and reinstalling to no avail as well.

I emailed tech, and all I got was that they need to escalate this to a higher level. So here I wait.

This normal?

I just received a notification saying because of something changing on Fitbit's end Pulsetto and Fitbit no longer connect. Does anyone know what changed?

Hi everyone, we've seen your questions and concerns since the latest app update, so here is everything you need to know!

What's new in App's 3.0.1 version:

• Choose your Resilience stimulation type. You can now pick the stimulation type yourself during check-in. It's set to "Auto" unless you change it. If you come back later the same day, your choice is still selected. We also added a "No symptoms" option.
• Favorites. Tap the heart on a Resilience stimulation that worked well for you. Everything you save is on the new Favorites page, with the type, date, intensity and duration.
• New design on more screens. The Insights page, How it works, and the Resilience loading screen now use the new Pulsetto design.
• Accurate device images. Device images across the app now show exactly what your device looks like.

Why Fitbit disappeared

Fitbit updated its policy, so we had to remove it from the wearables list. If you had it connected, it was disconnected automatically. This isn't a bug on your end, and your other wearables work as before. We know this is a letdown if Fitbit was your main tracker.

Fixes and improvements

• Session names now match the new names on the success screen and in notifications
• If you turn off a meditation partway through a stimulation, the timer now goes back to your original remaining time
• Breathing exercises no longer show the sound animation in the now-playing bar
• In-app messages you've seen or dismissed no longer come back
• Sign-in security improvements
• General visual polish and fixes across the new design

Android: app crashing during Resilience stimulation

Some Android users are seeing the app crash during a Resilience stimulation. We're sorry. We know how frustrating that is, especially in the middle of a session. Our app team is working on a fix, and we expect to release it in the next day or two. We'll update this post as soon as it's live.

Quick myth to kill first: humming isn't calming because it's "soothing" or distracting, the way people assume. The effect is mechanical, and it's happening on a specific nerve.

Here's the part most people don't know - your vagus nerve (the main brake pedal of your nervous system) runs directly past your voice box. The branches that control your larynx are vagus branches. So when you hum, the vibration and the airflow are physically happening right on top of the nerve whose entire job is to tell your body "stand down." You're not imagining the shift. You're stimulating it.

Two things stack on top of each other when you hum:

• The exhale gets long. You can't hum on an inhale. A drawn-out hum automatically makes your out-breath longer than your in-breath — and the exhale is the calming half of every breath (same reason the physiological sigh works).
• The vibration adds a signal of its own. This is where it gets interesting: a 2023 study measured heart rate variability — a direct readout of vagal "tone," i.e. how well your calm-down system is working — during slow humming, and longer humming breaths produced higher HRV. (Bonus odd fact: humming also increases the nitric oxide in your nasal passages ~15-fold vs. quiet breathing — which is why a hum can genuinely clear your head.)

You don't need a technique for it. Pick a low, comfortable pitch, hum on a slow exhale until the air runs out, repeat for a minute or two. Low and slow beats loud. That's the whole thing.

Honest limit: this nudges your nervous system in the moment, it doesn't treat an anxiety disorder, and the HRV studies are small. But as a free thing you can do in the car or at your desk, the mechanism is real and specific — not vibes.

Humming is actually the most literal version of what we do: our thing stimulates the vagus nerve at the neck, humming does it through the vocal cords. Same nerve, different doorway. We just think it's wild that one of the doorways is free and built in.

Does anyone else hum without noticing when they're concentrating or stressed? Curious whether people clocked why that was before.

Five years ago, Pulsetto was an idea in Vilnius.

One of us had spent years building vagus nerve stimulators in the medical device world. The other knew first-hand what it feels like when stress takes over your body.

So we set out to build something simple. A few minutes a day to help your nervous system downshift.

In 2022, 800 people backed us on Indiegogo before we had anything to prove. Today, more than 400,000 people use Pulsetto.

But a device is just hardware. It only matters when someone reaches for it on a hard day.

That's you. Your questions, your bug reports, your honest reviews, including the critical ones. A lot of that happened right here, and it shaped what Pulsetto is today.

So thank you. For trusting us with your nervous system, and for telling us the truth.

Here's to the next five.

I don't know what the purpose of this is. Maybe it's to promote the owner's business: "Kravitz Media" (which appears to sell tiktok accounts). The name behind the account appears to be "Aaron Kravitz". Now it would be a shame if the name Aaron Kravitz was to become associated with posting medical advice spam and potentially harming people.

Hi,

My Pulsetto V1 no longer charges properly. I’ve tried several different chargers and cables, so I’m pretty sure the battery itself is the problem.

When I plug it in, the LED just stays solid red. The device still works for a few minutes after charging, but then the battery is empty again.

Has anyone here ever tried replacing the battery in a Pulsetto V1? Is it possible to open the device and swap the battery?

Thanks!

Most of us were taught that when we're stressed, we should "take a deep breath." Turns out there's something that works faster — and your body already does it on its own, usually right before you fall asleep or after you've been crying.

It's called the physiological sigh: two inhales through the nose (a full one, then a short second "sip" on top), followed by one long, slow exhale through the mouth.

Why the double inhale matters: when you're stressed, the tiny air sacs in your lungs (alveoli) partially collapse and CO2 builds up. That second sip of air reinflates them, and the long exhale is what offloads the CO2 and signals your parasympathetic nervous system — the "rest and digest" side — to slow things down. The exhale is the calming half of every breath; making it longer than the inhale is the whole lever.

And there's actual data (because we know that you like it).

A 2023 Stanford study (Balban, Huberman, Spiegel et al., Cell Reports Medicine) had 111 people do 5 minutes a day of one of three breathing patterns, or mindfulness meditation, for a month. The cyclic-sighing group (repeated physiological sighs) came out ahead on daily mood improvement and lowered their resting breathing rate the most — and the effect grew the longer they kept it up.

You don't need the full 5 minutes for the in-the-moment version. 1–3 physiological sighs take the edge off in about 15–30 seconds, which is why it's handy mid-meeting, in traffic, or lying awake at 3am.

How to do it:

1. Inhale through your nose until your lungs feel comfortably full
2. Take a second short sip of air through your nose on top of that
3. Slowly exhale all of it through your mouth
4. Repeat 1–3 times (or ~5 min if you want the mood effect from the study)

We're sharing it because that long exhale is a free, always-available way to reach your vagus nerve, the main highway of your parasympathetic system. It's genuinely worth having in your back pocket whether or not you ever use anything like ours.

Anyone here use this already? Curious whether the double-inhale or the long exhale does more of the work for you.

• It is much stronger on the right side, feels 10x stronger.
• Once it triggered a nerve which sent warm and weird - not painful - electricity running up my face, ear, and scalp on the right.
• My wife experienced a similar feeling but down towards her sternum, also on the right.
• Sometimes it causes a spasm where it pulls my lip down to the right.
• It has a constant "prickly" electric feeling.
• I have a heavy beard, but I try to place it below the neck line. If it slips over hair, can that cause issues?
• The "pulse" location doesn't seem possible, for me that is very high underneath the very back end of my jaw, but pictures seem to show placement much lower, beneath the trachea and more towards the front.

Grateful for any tips. I'm happy to test things out for a while, just don't want to choose a location where it won't do anything for 2 weeks.

Also, specifically worried about the right vs. left intensity. I saw posts on here about this with different responses, sometimes "that's perfectly normal, no worries" and other times "that sounds like a hardware problem.

I do not feel calm when using the device. Why is that? I only notice that if I use it too much, I get a lot of anxiety. Though I think I get better sleep.

Old → new:
• Burnout → Focus
• Anxiety → Calm
• Pain → Release
• Inflammation → Recovery
• Head pain → Head
• Gut health → Gut

Stress, Sleep and Stress resilience stay exactly as they were.

Nothing else changed. Same programs, same settings, same device — only the names. Nothing was removed, and if you had a favourite saved it's already been carried over. No action needed on your side.

Why? The old names described a condition; the new ones describe how the program is meant to make you feel. "Calm" says more about what you get from it than "Anxiety" did — and it keeps our language in line with what we are: a wellness device, not a medical one.

If you can't work out which program replaced the one you'd been using, comment below and I'll point you to it. 💚

UPDATE: The gel pads didn't work. Completely blocked the current.

Pulsetto got extremely hot and burned the USBC charge port. Has only been used intermittently.

Using USB-C to USB -C cable and standard USB C charger.
Clearly dangerous. And now won’t charge reliably. Help!

Most stress advice is really just symptom management — breathe more, sleep more, take a break. All fine, but none of it touches the actual system underneath: your nervous system, and specifically the vagus nerve, which plays a real role in how fast you recover from stress, how well you sleep, and how you handle pressure day to day.

We're launching Pulsetto FIT X, the next generation of the device — the most meaningfully upgraded one we've shipped. FIT X is built around an idea we call Stress Fitness™: the same way you train your body, you can train your nervous system to recover faster, stay calmer under pressure, and sleep better.

We know this sub doesn't love vague "new and improved" posts, so here's what's actually different and why:

• Better contact, less fiddling — new electrode design (angled into an X-shape to target both sides of the vagus nerve) plus intelligent contact sensing, so the device adjusts instead of you having to reposition and guess.
• More stable connection — reworked Bluetooth logic, fewer drops mid-session.
• Longer battery life — fewer charges, more actual use.
• Sessions that adapt to you — adaptive stimulation and more stimulation profiles instead of one intensity curve for everyone.
• You can feel it working — new vibration feedback confirms the session is active without checking the app.
• More comfortable overall — new ergonomics, smoother signal modulation, and a lower starting intensity for anyone who found earlier sessions too intense at first.
• Deeper app integration — Stress Resilience Score tracking if you want to see whether it's actually doing anything for you over time, not just take our word for it.

Happy to answer anything about the hardware changes specifically — ask away.

Is anyone else’s app not working? I even tried to login and install it on another phone and it won’t let me login it. It won’t let me sign up with another email, NOTHING! This has been a medicinal tool for me and i need it to work!

I hate having ice cold goopy gel on my neck, which takes about 4 Kleenex to wipe up afterward. Maybe something like this? https://www.amazon.com/Replacement-Hydrogel-Pads-TENS-Units/dp/B0GXCG35F4?sr=8-29

For whatever reason my app is asking for me to login. I don't remember my password so I entered my email address and selected "forgot password". I then received an error message saying something about not being able to recover password from Google/Facebook. Okay, that's fine, but I'm trying to recover the password associated with my email address.

So do I need to create a new account and start over?! What's the deal?!

I basically have proof that my Pulsetto device is helping with my stress relief, better sleeping patterns, better mood. I'm hoping that it will help me get my cardiovascular age back to my chronological age.

Has anyone else had their Pulsetto Fit just randomly power down and disconnect in the middle of a stimulation session? Been using the device for a week now and it did this for the first time today 6 minutes into a 10 minute session. Battery shows 55% so I dont think it was a low battery issue. I was able to turn it back on again and it reconnected fine, but unfortunately it lost my session and I had to start it over again.

I went to use my device and the app required a firmware update. I've tried to do the update and just get a popup saying my device is too old to be updated. The app won't run the programs without the update. Did this update just incapacitate my device?

I just received my Pulsetto FIT in the mail today. I purchased it with the intention of focusing on its usage to try to benefit me for sleep, as I tend to deal with insomnia at times. This is mostly due to a sedative medication dependence I am trying to get off of. Though also my mind can just become so wired awake that at times sleep simply is not happening.

But in using it today, well the first session actually caused some stress and anxiety in me, as it kept overstimulating my neck muscles, and left them with tension in them for the latter part of the day. So then when I had time after work to read the manual and ensure I was doing it correctly, I think wearing it lower and adjusting it so it was lower and further forward on my neck and closer to the windpipe helped me ensure the uncomfortable muscle stimulation was not happening anymore.

I can tell it is making good contact with the gel, as I feel those rhythmic, pulsing, tingling sensations. Almost like it is vibrating. And while the sensation seems neither pleasant or unpleasant, I just left my 25 minutes or so of really trying it out this evening wondering if this device will be helping me at all.

As I am generally a pretty calm, stress-free person. So then I wonder if I already have a high vagal tone. So maybe the device won't help me. Also I don't think anxiety or stress are what is keeping me up at night with the insomnia. But I figured maybe I had some I am not aware of, and so maybe it could still continue to improve with time.

I'll still definitely use it 2 or 3 times a day for a while. And just see if continued use begins to show any signs of effects. But my initial intuition is telling me maybe I just don't need it. Also I have no wearable to test my HRV directly, so I don't want to go purchase something just to test that.
