Partially work

I was getting ready to send it back and decided to try once more.I do see some of the photos and videos that it transferred. But they also still showing on my iPad mini. I don’t understand that. The app itself doesn’t work with the usb flash. It doesn’t work at all with my iPhone 16 pro. I’m still trying to work with it because of some transfers. Overall I’m not satisfied with it. A 1TB flash.

The app was amazing before.

The application has several issues with the advanced updates. First, there is a bug in the dark mode. Second, there is an inability to share files with other applications. Third, and most importantly, the file locking tool with a password has disappeared.

I hope the issues are fixed so we can use your company's tools.
التطبيق فيه عدة مشكلات في التحديثات المتقدمة منها اولا هناك خلل في الوضع الداكن ثانيا عدم القدرة على مشاركة الملفات مع التطبيقات الاخرة ثالثا وهو الاهم اختفاء اداة قفل الملفات بكلمة سر

ارجو اصلاح المشكلات لكي نستخدم ادوات شركتكم .

Very limited & poorly presented

App can’t even handle files a few hundred MB large? What is this? The late 90’s ?? Good thing I only tried the app and didn’t buy their product. It can only open large files, but nothing else.

Crashes

When I got the new iPhone 14, this app crashes. Now I can’t back up my phone. Is there an issue with new iPhone and this?

Why don’t this work anymore?

I’ve got my flash drive for iOS and it is still able to be loaded on a PC but the app is dead weight on my phone and has been for a year or two. I hate to lose any data that I’m not able to offload on the drive….

Can’t update.

Something about a previous purchase. Won’t accept my information. I have several gigabytes of personal information that I have no access to now.

買PNY變孤兒

買了比別人貴的64G就算了,插上去連都連不上
試了三個PNY的DUO link App,沒一個能用
買產品只會變孤兒,就算拿來插電腦也只有C10的乞丐傳輸速度,丟也不是,不丟也不是,可憐啊

It's kinda crap, but it sorta works

Ya'll all get the last app upgrade? Crash on ya now? Yeah....

Is it that hard to make this simple lack luster app work?

Update: now maybe months to a year later I can only say this app works worse then ever

無法連線

麻煩請修正App,根本無法連上otg-usb!根本無法儲存,要如何解決!ios:14.3版本!iPhone XS!
110/2/1 還是無法連上,麻煩盡快修正,拖很久了!
110/2/9 沒有人可以解決這個問題嗎?買了備分otg,卻無法備份連上!這是什麼狀況!

I love it!

I bought the DuoLink 3.0 a few years back, and I have used it everyday. Unfortunately, mine was lost a few months back. I wish I could find a replacement drive, but they are no longer for sale

thank you for fixing the bug of not being able to access the audio files

aftre the update, I can not open any of the audio files, either mp3 , wma, or m4a files, either on the internal or external storage, using my iphone x or ipad pro.

after clicking the selected audio file, it went back to iphone or ipad homescreen directly without playing it.

all the other video mp4 files, and pdf files work normal as before.

閃退

換手機換App還是一樣繼續閃退

Bug? Mise à jour?...

Très satisfaite au début de cette clé! Permet de faire des transferts entre pc et téléphone facilement et/ou d’avoir un espace de stockage supplémentaire. Très pratique pour les sauvegardes de contact aussi!

Mais aujourd’hui, impossible!.....
Je m’aperçois qu’il n’y a plus de mise à jour depuis un petit moment...
Un abandon du développeur ?..
Cette clé devient peu à peu inutile pour le téléphone... elle devient une clé usb basique...
Démarche volontaire pour pousser à la consommation? Ou inattention du développeur ? Peut-on espérer une réaction pour corriger les bugs constatés?...

閃退

一直閃退,麻煩處理一下好嗎!

You made this app useless.It does not open any files on iPad

Once upon a time this app functioned (awkwardly).Your “fix something bug” made the whole thing a bug. The help button goes to a page that doesn’t exist.Fix it or get out of here

Lost my all data

It was working great and all if sudden today it was not opening, and shows no data there.
Is there any luck i can get my data again?

一直閃退

更新後一直閃退,早知道就不更新了

What happened

It use to work on the phone and after your up date, now it doesn’t work.

閃退嚴重

閃退嚴重,無法進入
