Does what I need. ### 1/5 — Horrible device *2024-10-02* After seeing all the hype on TikTok, I had to get one, as it looked very easy! You download the app only to be told that it’s not recognized. The only way to get your pictures from your phone is to the app! Won’t allow you to use an SD card which tells me they have access to all of your pictures on that app. No thank you. ### 4/5 — My iUSB *2024-10-02* I don’t know why but my iUSB is locked up and I can’t access it now!! What can I do? ### 1/5 — Better than some reviews but not good *2024-04-08, version 1.0.36* I can access my SD card but without CR2 / raw image support, or the ability to filter files by date/time and then select all, this app is hard to use in order to export 500 photos from your SD card while travelling without a laptop. ### 1/5 — Does not work *2024-04-03* My phone does not recognize it’s plugged in. This is the worst $20 I’ve spent HIGHLY DO NOT RECOMMEND ### 1/5 — USB photo card storage adapter *2024-03-22, version 1.0.36* Totally agree with the other reviewer. My iPad can “see” the adapter but that’s as far as it gets. No options appear, cannot communicate with the device. ### 1/5 — App opens to white screen and shuts down *2024-02-09* I can’t even get the app to start properly. ### 2/5 — Iusb won’t recognize on my iPhone 14 *2023-12-13* It never recognizes it has been plugged into my iPhone - immediately opens on laptop but I needed this to open card reader on my IPhone ### 1/5 — Not working *2023-12-13* The app closes out as soon I open it. It won’t work at all Frustrating ## Frequently asked questions about iUSB ### Does iUSB have ads?
