ViHealth Alternative for the O2Ring: Remote View & Alerts

You bought a Wellue O2Ring to keep an eye on oxygen levels — maybe your own overnight, maybe an aging parent's, maybe a family member recovering from a chest infection. The ring works beautifully. But then a question shows up: which app should you actually use with it? The official ViHealth app does a lot well, and for many people it's all they'll ever need. For others, there's a specific gap that a second app fills. This is an honest look at both, so you can pick the right one — even if that turns out to be the one you already have.

First, what ViHealth does well

ViHealth (sometimes called Viatom) is the official, free app made by the company that makes the O2Ring. It's a solid piece of software and it deserves credit. If you're monitoring yourself and you have your phone with you, it covers the essentials cleanly.

• It's free and made by the manufacturer, so it's fully supported and updated alongside the hardware.
• Live on-device viewing: open the app near the ring and you see real-time SpO2, pulse rate, and motion.
• Overnight recording stored on the ring itself, then synced to your phone the next morning.
• Clear reports with oxygen-drop counts and trends, plus CSV/PDF export you can hand to a doctor.
• Vibration alerts on the ring itself when oxygen dips below your set threshold — felt on your finger, no phone needed.

That last point matters: the O2Ring's buzz-on-your-finger alert is a genuinely good feature for the person wearing it. If you're monitoring your own sleep and the ring waking you up is enough, ViHealth alone may be all you need.

The one real limitation

Here's the honest wedge — not a knock on ViHealth, just how it's built. ViHealth shows live data on the same phone, within Bluetooth range, with the app open. That's perfect when the person watching and the person wearing the ring are the same human in the same place.

But step out of that scenario and it stops working. You can't open ViHealth on your phone in the kitchen and watch a reading from your mother's O2Ring upstairs — the data lives with her phone, near her ring. You can't get an alert on your own phone when her oxygen drops in the night. And there's no live view from another city. The ring's vibration buzzes her finger; it doesn't reach you. For self-monitoring that's fine. For caregiving, that gap is the whole problem.

What OxyRemote adds

OxyRemote uses the exact same O2Ring sensor — your loved one still wears the same ring, and the readings come from the same hardware. It is not more accurate, and it doesn't replace the sensor. What it adds is a remote layer on top: the live numbers and alerts travel to a second phone, in another room or another country. If you want the deeper background on why that matters, see monitoring an elderly parent's oxygen remotely.

• Remote live view: watch SpO2 and pulse on your phone while the ring is on someone else's finger elsewhere.
• Remote low-oxygen alerts: a push notification reaches your phone when their oxygen drops below your threshold — not just a buzz on their finger.
• Apple Watch support: glance at the latest reading and get alerts on your wrist.
• Helpful for overnight watching from another bedroom, or checking in on a parent in another city.

OxyRemote is iPhone-only. It complements ViHealth rather than competing with it — many people keep ViHealth for reports and exports, and add OxyRemote purely for the remote-monitoring piece.

Side by side

• On-device live view: ViHealth yes / OxyRemote yes — but only OxyRemote shows it on a second, remote phone.
• Remote view from another room or city: ViHealth no / OxyRemote yes.
• Alerts: ViHealth buzzes the ring on the wearer's finger / OxyRemote sends a push notification to a caregiver's phone (and Apple Watch).
• Apple Watch: ViHealth no / OxyRemote yes.
• Reports, CSV/PDF export: ViHealth yes (and very good) / OxyRemote focuses on live remote monitoring, not record-keeping.
• Cost: ViHealth is free / OxyRemote is a paid app for the remote layer.
• Sensor you still need: both use the same Wellue O2Ring — you always wear the ring.

Which one is right for you

Stick with ViHealth if you're monitoring yourself, you keep your phone nearby, and the ring's own vibration alert is enough to wake or notify you. You'll also want ViHealth for pulling reports — for example when you're tracking patterns for sleep apnea or sharing data from overnight monitoring at home with a clinician.

Reach for a remote-monitoring app when the watcher and the wearer are different people in different places — checking on a parent overnight from your own bedroom, or keeping an eye on someone managing COPD oxygen levels at home from across town. If you're weighing your options more broadly, the guide on choosing a remote pulse oximeter app walks through what to look for.

Whichever you choose, it helps to know what the numbers mean — what counts as a normal SpO2 reading is a good place to start. And if you're still deciding on hardware, the Wellue O2Ring is the sensor both apps are built around.

The honest bottom line

ViHealth is free, official, and genuinely good at on-device viewing, reports, and exports — if that covers your situation, you don't need anything else. The single thing it can't do is put live readings and alerts on a caregiver's phone somewhere else, and that's exactly the gap OxyRemote is built to fill: the same O2Ring you already wear, with a remote view and low-oxygen alerts on your iPhone and Apple Watch. No pressure either way — the right answer is whichever one matches who's doing the watching.
