ok if it works

on a good day, it's buggy with connection issues. unfortunately, it stopped connecting entirely after six months and I've been unable to control pain for weeks now with no update from the company. had no issues with the old school remote I used for over eight years previously.

Long-Term Success

After 18 months with the NEVRO Spinal Cord Implant and this app, it has earned a 5-Star Review. After having been fully crippled by chronic pain (unable to sleep and unable to take a deep breath), NEVRO has provided real relief.

The App is very helpful, especially when used in tandem with the NEVRO Care Team. It did take a few months to get the device focused at its best. The Care Team patiently walked me through step by step adjustments with the app.

Did the device provide 100 percent relief? No. A cocktail of prescribed medication is still part of my daily routine. And I am still disabled by the chronic nerve pain. But the NEVRO device and this app have provided tremendous benefit to the quality of my life.

If you are being disabled by chronic pain, I encourage you to speak with your physician and explore NEVRO’s products to see if they might be helpful to you.

This app is a piece of trash. No matter where I go in my house I can’t get it to connect via Bluetooth.

How is the rep supposed to see my improvement to be able to adjust or tweak my program?

Crazy Lady

DONT DO IT.

Problem with app?

For he last few days when I try to open the HFX app to do my daily review, all I get is a white screen. What is going on??

Dark Mode Please!

Can You please add an option in settings to set the Home Screen to dark mode please????? So sick of being “BLINDED” by the frigging white Home Screen!

White screen!

I've had this app for almost a year. It has worked fine up until last week. Now all I get is a white screen. What's up? I can no longer keep up with my progress or do my daily assessments. This is my lifeline! My pain has been relieved by up to 80% but it seems I have been cut off from contact! I feel fine, so I am fairly confident that the unit is doing it's job, but I have developed 5 points of high impedance that are very concerning. Help!

Frustrated and over it!!!!

Let me just first start off by saying…. When it works, it’s amazing! I have provided such a low rating due to the several frustrations in using this product for the past two years.
1. Repetitive issues with the app not working correctly.
2. Dropping off the network, requiring a face to face visit from Nevro rep to get my stimulator “back online”. So, so, so very inconvenient! (Time off work, scheduling appointment that must be at the doctor’s office) Multiple challenges with that! My last appointment with Nevro I learned that the “very small pizza” on the charging pad must hit the EXACT center of the stimulator in your back. NGTL…. MF has taken a few flight trips across the living room, which only leaves me extremely frustrated and hopeless, along with excruciating pain! Worst design ever!!
3. I have spent hours attempting to place the charging pad against the device in my back. Belt pocket for charging pad is the worst design ever!
4. You have to take time to charge every other day.

Today I am dealing with the white screen. This is a new thing for me but I have read some reviews mentioning this. I wish someone would post resolution.😩

I’ve taken steps to have device removed.

Frustrated

This app is so difficult to connect to Bluetooth. I don’t have problems connecting to Bluetooth with anything else but HFX! I have never had to restart my phone so much. I’m about to just be over it.

App no longer loading

The device is still working but the app no longer loads and gets stuck on a white screen. I am not able to adjust the device settings for differing levels of pain. I have an iPhone 12 Pro Max.

In Need of Updates

The only time the assessment alert worked was when phone couldn’t connect to device. Assessment portion is too vague, contact me for useful update suggestions. You responded to my earlier review asking for my input by giving me the phone number for my personal care team!?!?! I have told them time and again of my suggestions. If you really want my constructive input give me a phone number of one of your software engineers.

Useless

This is 10 year old technology absolutely useless

White screen

My screen went white on Thursday and I called the Nevro number and she called me back we tried several things and the screen remained white. She told me she would have somebody else call. They called back and we do a couple things and we got disconnected. I tried calling back and left a message again. It is Saturday night and I called and left another message.

Works NOW

I had my device replaced yesterday, as it was a dinosaur compared to this new one. So far it’s working flawlessly. No white screen like mentioned earlier. I have nothing but good things to say about Nevro. I’m a walking miracle and they helped me back in 2017. Thank you for making my life Fun again.

App not working

The app isn’t working and I’m in extreme pain. I’ve tried to re load it but can’t. It’s been down for days. What’s is happening?

Frustrating!!

This app has so many glitches. For what my insurance and out of pocket I paid for this stimulator, it should be perfect. It takes several attempts to connect to WiFi. I get errors and then it connects. When I try to change to a favorite setting, the tabs swap, forcing me to close and open several times to get it to switch back. I do assessments everyday but when I go back to see trends, there are days that say no data collected. They need to fix these issues.

The implant is terrific. The app is hugely disappointing

I kind of wish that I would have checked app reviews before, y’know, having their device surgically implanted into my body- but who would have expected the companion app to suck?

The app will pair to the implant. But I have NEVER consistently received reminders. Only after I open and close the app several times will the app seem to “remember” that it is paired. Yes, I have spoken to my Nevro rep and the tech team. They’ve been looking into it for months. Nothing has helped.

I’m glad that I can at least do the surveys and make adjustments, I just wish that I could actually get alerts from my implant.

The Nevro pain management technology itself and the Nevro representatives seem great, but with the app being so central to the experience I’d be wary of recommending Nevro to others

Stop working, now not synching

I was really enjoying my app until a week ago the screen went blank. I thought itbwoukd fix itself, nope it didn't 👎. So, I deleted the app, maybe thinking re-installing may help. It didn't 👎 It will not even locate my device at all. Welp, I just went on and broke out the good ole remote control and dropped the app. If they fix, I might install it again but they need to keep up with clearing these bugs.

HFX

App freezing up! For the last 3 days I’ve been unable to use the stimulator, because every time I go to use it the app freezes up! I need an update fix please!!

Problem

The app was working fine till about two months ago then it when white but I have had problems with getting any kind of pain management since they did a manufacture update and since I have had nothing but trouble and I went through a revision and it still isn’t working like it use to unfortunately.
