I have tried everything. I have searched options. I had a friend try. I even took it to IT at work. Absolutely useless. I am so angry. Waste of time and money. ### 1/5 — It will not connect *2025-10-20, version 1.1.21* Like others, I have tried several times to connect this camera to the app and it does not work. I have tried the. Wi-Fi, which wants to connect it turns the camera off and the app doesn't show any photos. I tried Bluetooth and it connects, but the app still says it needs to add the camera. ### 2/5 — Do not buy *2025-10-13, version 1.1.21* The controls and setup are almost impossible to make work. With an iPhone 16 I have yet to connect or to download photos. Controls on camera sometimes work-sometimes don’t. If I could take this back I would ### 1/5 — Old app works better. (NBD s210) *2025-10-05, version 1.1.21* Doesn’t work for NBDs210 What does work , is the SBC app (single board camera) I’m guessing this camera only uses one logic board?or processor? I don’t know what you guys are engineering. ### 1/5 — Download SBCapp instead *2025-09-03, version 1.1.21* Delete this app and download SBCapp instead. This app is absolutely horrible. Camera connects to phone wifi just fine but will not connect to the app, will turn the camera off every time I try to connect and then said failure to preview to sd card error or something like that. I found another app SBCapp I downloaded it (ignore the fact it says business) and it connected instantly! I can now easily download pictures from my camera!! ### 2/5 — Can't find the transferred media from camera to iPhone over WiFi *2025-08-25, version 1.1.21* No problems connecting to an action cam with wifi and controls the camera fine. Problems start when I try to transfer media over WiFi. It's very slow over WiFi but the problem lies in viewing videos. Once you start playing one you cannot go back to the menu and have to restart the app. Also the media is nowhere to be found on the iPhone. It does not store them in photos or videos and there is no folder created on files? Where are they stored. Resorted to taking the camera out of its case and taking the memory card out in the end. It's a bit of a faff. ### 1/5 — My camera shuts off *2025-08-15, version 1.1.21* The WiFi will connect to the phone, but every time I go to connect it in the app, the camera shuts off. It’ll stay connected as long as I don’t open the app, but the second I do, the camera shuts down. I’ve tried this both on my phone and iPad. ### 2/5 — Won’t wifi connect. *2025-08-14, version 1.1.21* Everytime I try to conmect my camera to my app it takes to long for the wifi connection to work and the camera just times out. It is not easy to use nor is it accessible. But the quality on the camera is pretty good and its fun to use. Still, if you’re looking for the wifi easy access, this fumbled hard. ### 1/5 — won’t let me leave *2025-07-30, version 1.1.21* No matter what I do, after I have connected it wont let me leave my WiFi information on my camera. I have deleted the app and reinstalled it, turned off my camera multiple times and even waiting an hour for it to try and load. It’s become ridiculously annoying and if I could give this app no stars at all I would… but people have to know that this app is a complete joke. ### 1/5 — Rezil *2025-07-25, version 1.1.21* Bi türlü videoları telefona aktaramadım sürekli hata veriyo tavsiye etmem ### 1/5 — Wi-Fi *2025-07-15, version 1.1.21* Wi-Fiが繋がらない　デバイスの再起動、ルーターの再起動、ソフトアップデート最新…あらゆることをしても繋がらない。 ### 1/5 — Don’t get an apex cam *2025-07-14, version 1.1.21* Has trouble even connecting than when you manage to actually connect it says failed to find sd card when you clearly have one in ### 1/5 — 😅 *2025-07-14, version 1.1.21* Not as easy as I thought ### 1/5 — App turns camera off *2025-07-12, version 1.1.21* Everything works fine until you actually try to connect the camera to the app, at which point it turns the camera off instead.
