This defeats the purpose of getting the reader as I might as well plug in to my computer to transfer the files.

My iPhoneX is 256GB...how many time for copy and back up for once? ### 1/5 — Crashes in iOS 14.0.1 with 128GB card *2020-10-21, version 1.1.0* App was functional despite niggling issues, but now crashes every single time I try opening a 128 GB microSD card with iDrive. Please fix! ### 1/5 — This app retired, look for photofast app *2020-10-03, version 1.1.0* This app is dead, no wonder it doesn’t work. What a waste of time!! Downloaded the photofast app and that works for the external usb flashdrive. ### 1/5 — App Crash *2019-12-18, version 1.1.0* I am wondering if this app is ever tested.. the moment i select files to copy it crashes. I am using iOS 13.3. I hope developers of this app will release the patch for the app crash asap otherwise this money is waste for us. ### 1/5 — Useless device *2019-08-11, version 1.1.0* Device not working.

I love this app…… ### 5/5 — Good *2019-11-05, version 1.1.0* The 64GB & 128GB iDrive I bought work well on my iPhones. Able to transfer photos to and fro between iDrive and iPhones. ### 4/5 — Integration with Files in iOS *2021-06-23, version 1.1.0* The app is really good as it gives me that extra capacity. It would be great though if this app could be integrated with the new Files app introduced in ios 11 or later. ### 4/5 — Please add Rename Feature *2016-07-06, version 1.0.3* It works well. Fast transfer speed than expected to the iDrive, 128MicroCard 466X. Just found out the under External Drive, there is no rename feature. Hope the next update is available. ### 3/5 — Not working *2026-06-06, version 1.1.0* Hi, this app no longer works on iso 26! Can you update the app pls with fix?? ### 3/5 — Excellent *2018-08-30, version 1.1.0* Update: what happened to “save to camera roll” ? Cannot find now. >>Transferred photos to and fro sd card. No hassles! Transferred a few gb of audio files from sd card to ipad: took a couple of min. App is easy to use. Only thing is that the app does not offer true file manager functions: could not see size of folder before transferring. V happy that iOS now has external flash storage connection ie forget about buying high gb iOS. Just get this and sd cards. Looking fwd to plugging in pics from camera to view on ipad. ### 2/5 — Did work great *2018-06-14, version 1.1.0* Worked great when I got the adapter but now won’t save to external device. Saving photos in app is useless to me as I’m needed to reset my phone. ### 2/5 — Fast file retrieval, plays video files, however no Landscape mode *2017-10-20, version 1.1.0* The iDrive card reader is fantastic for reading of files on my iPhone and iPad easily. Read times are fast, and easy to navigate through the app. Plays a wide array of file types, however, videos are only played in Portrait mode. It would have been a great feature to have included landscape view for all video files. Please bring that feature to the app. ### 2/5 — App keeps crashing *2017-10-08, version 1.1.0* Just bought a 128gb micro sd card with idrive card reader yesterday. So i try transferring my files. It keeps crashing no matter what i do. I cant even play video from the app. Really hope u guys fix the issue. Im running on ios 11 by the way. ### 2/5 — Not Working on my iPhone7+ with iOS 10.2 *2016-12-28, version 1.0.4* I bought the 64GB unit at Dubai airport on my way traveling back home, but unfortunately I could not get it to work, may be because my iPhone 7+ has the latest iOS 10.2 installed. The features in the App seem to be ok but I couldn't test them 😩 , please fix the problem. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
