HeyCyan smart glasses: the app, the setup and the fixes.
If your glasses told you to download HeyCyan, or you saw the name on a listing, this is what it is. HeyCyan is the free phone app that a lot of camera-and-audio glasses run on, ours included. Here is what the app does according to its own store listings, how to set it up, the problems people hit most often and how to fix them, and why who sold you the glasses matters more than the app.

What are HeyCyan smart glasses?
HeyCyan smart glasses is the name people give to glasses that run on the HeyCyan app. The glasses hold the camera, the open-ear speakers, the microphones and a battery. The app on your phone is where you pair them, change settings, import what you captured, and reach the translation and AI features. HeyCyan is the app, not one glasses maker, which is why the same name turns up on frames sold under different names and on unbranded marketplace listings.
The app is published by Shenzhen Qingcheng Future Technology Co., Ltd., listed as the seller on the App Store and as “Glasses Dev” on Google Play. OXIVUE frames use it as their companion app: the M02Ccarries the “Hey Cyan” wake word for its visual assistant, and the M14lists 139-language translation “in the HeyCyan app” on its spec sheet. If you want the wider picture of how the glasses, the phone and the cloud split the work, our guide to how AI glasses work walks through it.
What the HeyCyan app does
The developer describes the app on its two store pages. Taken together, the HeyCyan app does five jobs:
- Pairing and control. Bluetooth pairing, volume, gesture settings and system (firmware) updates for the glasses.
- Importing photos and videos.The Gallery tab is where you import, view and share captures. The App Store listing says the app uses the glasses’ own Wi-Fi module as a hotspot to move files to the phone.
- Battery and network status. Remaining battery and network use, shown on the phone.
- Voice control.Setting up hands-free voice commands. The Google Play listing spells the phrase “Hello HeySyan”; on the OXIVUE M02C the wake word is “Hey Cyan”.
- AI and translation.The App Store listing says you can add “a variety of AI agents” through the app. Translation runs through the app too, and you hear it through the glasses’ open-ear speakers.
Here is what each store listing showed when we read them on September 30, 2026:
| Listing detail | App Store (iPhone) | Google Play (Android) |
|---|---|---|
| Price | Free, no in-app purchases listed | Free, no in-app purchases listed |
| Publisher | Shenzhen Qingcheng Future Technology Co., Ltd | Glasses Dev (same Shenzhen company) |
| Last updated | Version 1.4.0, September 29, 2026 | September 29, 2026 |
| Requirement | iOS 13.0 or later · 260 MB | Not stated on the page |
| Rating | 2.7 from 292 ratings | 2.8 from 2.33K reviews · 500K+ downloads |
| Privacy declarations | Email address and user ID linked to you; audio data not linked | Data encrypted in transit; you can request deletion |
Those ratings are not flattering, and we would rather you read them here. The most recent reviews we read describe three things: the wake word not responding, the app needing a log-in before you can import, and glasses that never paired. The setup steps and fixes below are aimed at exactly those. OXIVUE’s own support page asks for iOS 14 or later and Android 9 or later.
How to connect HeyCyan smart glasses: setup in 8 steps
- Charge the glasses fully before the first pairing, so a firmware update offered during setup can finish.
- Install HeyCyan from the App Store or Google Play. Check the publisher name above, because several similarly named glasses apps exist.
- Turn on Bluetooth and Wi-Fi on the phone. Bluetooth is the everyday link; Wi-Fi is used when you import photos and videos.
- Open the app and sign in or register, while you have an internet connection.
- Pair from inside the app,not from the phone’s Bluetooth menu. Put the glasses on or power them up, and let the app find them.
- Allow the permissions it asks for: Bluetooth, microphone (for voice control and translation), and Photos, so imported captures can be saved to your library.
- Install any firmware update the app offers, with the glasses charged and close to the phone.
- Test each feature once: take a photo, import it, play a song, make a short call and try one translation.
The phone stays part of the system after setup; our guide to whether smart glasses need a phone lists what still works when the phone is out of reach.
HeyCyan glasses problems and how to fix them
These are the problems that come up most often with HeyCyan-based glasses, with the fix to try first.
| Problem | Most likely cause | Fix |
|---|---|---|
| Videos don’t save to the iPhone photo library | HeyCyan has no permission to write to Photos | Settings → HeyCyan (under Apps on recent iOS) → Photos → allow access. Then import again from the Gallery tab. |
| Photos never appear on the phone | Captures were never imported | Captures move to the phone only when you import them in the app with the glasses connected. Open the Gallery tab and import. |
| Import fails or stalls | The phone did not join the glasses’ Wi-Fi hotspot | Keep Wi-Fi on, accept the prompt to join the glasses’ network, keep the phone close, and restart the app and glasses if it hangs. |
| Glasses don’t show up when pairing | An old pairing, or pairing from the wrong place | Forget the glasses in Bluetooth settings, restart phone and glasses, then pair from inside the app. |
| The wake word doesn’t respond | Voice control off, or no microphone permission | Turn voice control on in the app, allow the microphone, and say it clearly. On OXIVUE, the wake word is on the M02C. |
| Can’t import while travelling | The app wants a log-in, which needs internet | Sign in before you leave, and import when you have a connection. |
If none of these work and your glasses came from OXIVUE, write to us through support with your order number and what the app shows. A fault after delivery is repaired or replaced under the 2-year frame warranty.
Does the HeyCyan app need an account or a subscription?
It needs a HeyCyan log-in, but no platform account and no subscription. Here is exactly what the sources say, because this is easy to get wrong.
- The privacy policy linked from both listings describes registering an account with an email address or phone number, a username and a password.
- The App Store privacy label lists email address and user ID as data linked to you.
- The “Sign in with Google” button at the top of the Google Play page is Google Play’s own store sign-in, which appears on every Play page. It is not a statement about how the app logs you in.
- Neither store lists in-app purchases, and OXIVUE charges nothing after you buy the glasses.
What you do not need is a Meta, Facebook or Instagram account, which Meta’s glasses tie you to. Our guide to smart glasses without a Meta account compares the two set-ups.
Which OXIVUE frames work with the HeyCyan app
All four of our in-stock frames pair with HeyCyan. They differ in weight, water rating, the number of translation languages and what is built into the frame.
| Frame | Price | Weight | Translation in the app | What sets it apart |
|---|---|---|---|---|
| M08 | $149 | ~42 g | 40+ languages | 8 MP camera, three lens options, 7 h listening |
| M02C | $159 | ~41 g | 40+ languages | “Hey Cyan” visual AI, Sony 219 sensor, IP65, magnetic charging |
| M08C | $169 | ~42 g | 40+ languages | Gold or silver trim, three lens options |
| M14 | $199 | 52 g | 139 languages | Wrap shield, 4 GB onboard memory, Wi-Fi file transfer, IPX4 |
Translation is heard only by the wearer, through the open-ear speakers; there is no display in any OXIVUE lens, and none takes prescription lenses. Every spec sits side by side on the comparison page.
HeyCyan glasses from a named brand vs an anonymous listing
Because the app is shared, two pairs of glasses can show the same HeyCyan screens and still be very different purchases. The app does not tell you what is inside the frame or who answers when something breaks. Before you buy, check:
- Is there a seller you can reach? A named brand with a support address and an order number to quote, not a listing that disappears.
- Is the warranty written down? OXIVUE covers every eyewear frame for 2 years against faults, with repair or replacement.
- Are the specs published? Camera, weight, battery, water rating and translation languages, in writing, so you can hold the seller to them.
- Are the policies plain?OXIVUE does not offer change-of-mind refunds; the only exception is damage in transit. Read any seller’s policy before you pay.
- How long is delivery? OXIVUE ships US orders in 5–9 business days and international orders in 9–14 business days after shipment, free from $99.
Bottom line
HeyCyan is a free companion app, not a brand: it pairs the glasses, imports your photos and videos, and runs translation and the AI through your phone. Expect to sign in to it; you will not need a Meta account or a subscription. Most problems come down to permissions, importing and pairing from inside the app. If you want HeyCyan glasses from a brand that publishes its specs and stands behind the frame for 2 years, start with the OXIVUE M02C at $159, the frame built around the “Hey Cyan” visual assistant, or the M08 at $149 if price comes first.
Frequently asked questions
What are HeyCyan smart glasses?
HeyCyan smart glasses are camera-and-audio glasses that pair with the free HeyCyan app on your phone. HeyCyan is the app, made by Shenzhen Qingcheng Future Technology, not a single glasses brand, so frames sold under different names use it. OXIVUE's four in-stock frames, from the $149 M08 to the $199 M14, use it for pairing, photo import, translation and the assistant.
How do I connect HeyCyan smart glasses to my phone?
Charge the glasses, install HeyCyan from the App Store or Google Play, turn on Bluetooth, open the app and sign in, then let it find the glasses and pair from inside the app rather than from your phone's Bluetooth menu. Allow the Bluetooth, microphone and photo permissions it asks for. If the glasses do not appear, forget any old pairing in Bluetooth settings, restart both devices and try again.
Why are my HeyCyan videos not saving to my iPhone?
Usually because HeyCyan does not have permission to write to your photo library. Open Settings, find HeyCyan (under Apps on recent iOS versions), tap Photos and allow access. Then import again from the app's gallery. Captures move to the phone only when you import them through the app with the glasses connected, so a clip you shot will not appear in Photos on its own.
Do you need an account for the HeyCyan app?
Expect to sign in. The app's privacy policy describes registering an account with an email address or phone number, and its App Store privacy label lists email address and user ID as data linked to you. That is a HeyCyan login, not a Meta, Instagram or Facebook account, and there is no subscription: the app is free and neither store lists in-app purchases.
How much do HeyCyan glasses cost?
The app is free; the glasses are priced by whoever sells them. OXIVUE's HeyCyan-compatible frames are the M08 at $149, the M02C at $159, the M08C at $169 and the M14 at $199, currently with $50 off one pair applied automatically at checkout. Each comes with a 2-year warranty on the frame and free shipping from $99.
Are HeyCyan glasses worth buying?
They are worth it if you want hands-free photos, open-ear music and calls, and translation through a phone for well under the price of Meta's glasses. Go in with clear expectations: there is no display, the AI runs through the phone, and the app is rated 2.7 on the App Store and 2.8 on Google Play. Buying from a seller that publishes specs and a warranty matters more than the app.
Does HeyCyan work without internet?
Not fully. Translation and the AI assistant need the phone and a data or Wi-Fi connection. A Google Play review from August 2026 also reports that the app asks you to log in, which needs internet, before importing photos. If you are travelling somewhere with patchy coverage, sign in before you leave and import while you have a connection.
Is the HeyCyan app safe?
Judge it by what the developer declares. Google Play says data is encrypted in transit and that you can request deletion; the App Store label lists email and user ID as linked to you and audio data as not linked. As with any camera wearable, the bigger privacy question is how you use it: tell people when you are recording, and check local recording laws.
