Typical Chinese company decent hardware and atrocious software. UX is a mess, limited features and it is IMPOSSIBLE to update firmware using this app.

Works perfectly with A329T
Connecting to Wi-Fi could be a smoother less complicated process and would recommend doing firmware updates on a computer.
Why?
In short, it didn't work well for me. On popular dash cam review channels, I ask in the comments why a higher rated dash cam in reviews has a badly rated app compared to other high end dash cams. So far no responses.
Poor app
I’ve never felt the need to write a review on any of the apps I’ve placed on my iPad or my iPhone. I finally had to write it on this. Honestly, the older one worked OK. I installed this new one so that I could do OTA updates. Viofo should be embarrassed that they would put out such a poor application. I’ve tried every fix that I could find on the Internet and even head to Google AI find a couple that I did not and they all failed resolve the crashing when I try to get into the phone using the app. I’m able to connect to it, but then can’t do anything otherwise it crashes. Viofo advertises OTA updates along with being able to access the video, but sadly, this is not the case at least in my case. If I could write this less than one star I would. With the amount of cameras that they sell, you would think they could pay at least one software engineer to write a decent application

Disconnects & crashes
I should have looked at the app reviews before buying the dashcam. It disconnects and crashes a second after trying to do anything.
Cool
I’m impressed so far could be better if a small guide was in the app on how to use camera features
Video Synthesis in Progress Problem
My App no longer gives me access to my locked photos or videos. Whenever I try to review or delete one the App says video synthesis in progress. I hit OK and it closed the App. I used to be able to open, edit, delete, and save edited versions. Now, I can’t do anything to them
Only function is crashing
I have the A139 Pro. Loaded the app, hooked it to WiFi, and every time I would connect to camera it would crash. I tried the help menu which works equally as well. It doesn’t matter what you type, it takes you to the same page 5 item suggestions that have no connection to the problem. I reinstalled the old app. Not great either but at least it works. Will be upgrading soon but will be looking for another brand.

WiFi Disconnects
Have a A329S and IPhone 15+, no matter 5ghz, 2.4ghz, disconnects while trying to play parking videos after 30 seconds. Old app works this is a POS.
Works okay with A321S.
Even lets me update firmware.
Slow and almost worthless
This app is the worst app I own. Why even use it. Super
slow and constantly having to restart. I can see my videos but they won’t playback. This app needs work. I’d give a 1 star but I’m hoping it gets better. If not I may return the camera for a better one.

Decent!
I use the A229 Ultra 3 Channel and I’ve had a pretty good experience with this app. The only gripe I have with it is that after every setting change you have to wait about 3-5 seconds for it to update before you’re able to change another setting. I wish you could just change multiple at once and then save the settings.
I have not had any disconnection issues with the IPhone 16 Pro Max while using the camera. It only really happens if my phone decides to auto connect to my home WiFi if I’m in the vicinity of the connection. But I just disable auto connect if I’m near a known WiFi network that it will try to auto connect to.
I like this app A LOT more than the original because you can do over the air updates now!!
All in all, I like the app!

Love the New App
The new app works great, love the over the air firmware updates. Kudos to the VIOFO developers.
Big fan! Excellent app.
Glad I re-downloaded this app. All known bugs & Ul issues have now been resolved. This app does exactly what I'd expect it to. My compliments to all of the developers and design team. I give this app my highest recommendation. Thanks.
Turn off Bluetooth if you have CarPlay or Android auto to keep WiFi stable.
Works great. A lot of these negative reviews are misguided it seems You need to turn off Bluetooth on your phone if you have CarPlay or Android auto to keep WiFi stable. Your phone can only connect to one Wi-Fi device at a time. You shouldn’t be driving around with the Dashcam Wi-Fi on. You only turn it on when you want to make a settings change or download a video recording. You don’t drive around with the App open.

If I could rate it ZERO I would
This new app can not connect to the WiF thus making it useless
Does not work with the A139 pro
As of May 6, 2026 latest update to the app still does not work for my A139 Pro
Not much else to say from the title. Downloaded this new version for the iPhone appears to connect to the a139 pro with a green checkmark but every time a tap on the Enter Dashcam cam just crashes the app over and over and over. I have uninstalled reinstalled multiple times to no avail.

Worse than useless
Disconnects from the unit literally 5 seconds after connecting. App is literally useless. Actually makes me question buying a Viofo.
Viofo: great hardware, terrible software
Viofo’s brand would be so much stronger if they just invested in building a proper app that actually worked. Both viofo apps (this “dashcam” one, and the “viofo” app) suffer from terrible UI design, slow response times, and frequent bugs. For example, the app will randomly disconnect from the dashcam about once every 2 minutes, making it borderline unusable. The dashcam hardware works great, but the app is very rough.
Overall, the app WILL let you use your dashcam, but it will be an infuriating experience as the software feels like it hasn’t been updated in decades.

App crashes accessing media
When connected via dashcam wifi, enter camera, tap album, the list displays video, parking impact files. Tap to open album and app crashes.
