### 1/5 — Avoid

*2026-08-22*

If I could leave negative I would, it expects you to pay an extra £2.99 for exFAT file system support or £6.99 for all file systems . Considering you already pay £0.99 for the app in the first place!

**Developer response:** Both the App Store description and the support site (https://disk-decipher.app/filesystems/) explain that the extra purchase is needed to cover 3rd party licensing and royalties costs.

### 5/5 — Läuft Super auf IPad Pro M4

*2026-06-12*

Vielen Dank für dieses super Programm. Es kann problemlos die Inhalte meiner „alten“ TrueCrypt-Container auf IPad Pro anzeigen. Eine Spende schicke ich später noch an den Entwickler!
Einen Wunsch hätte ich noch für ein Update: In meinem Container liegen viele Bilder und der Rahmen der Thumbnails ist sehr Groß bzw. Dick! Wäre es möglich diesen viel kleiner/dünner zu machen bzw. eine Option die Dateinamen auszublenden!

**Developer response:** Danke für die Idee! Ich habe dafür einen Feature Request angelegt. Sie können ihn hier verfolgen: https://gitlab.com/huv/disk-decipher/-/work_items/388

### 5/5 — Top

*2026-05-01*

Em 2026 funciona perfeitamente, muito top!!

### 3/5 — Problème pour l’écriture.

*2026-04-30*

Bonjour. Merci pour votre application. 
Je signale un problème. Les disques locaux sur iPad fonctionnent parfaitement. Mes disques sur cloud : PCloud et Dropbox, ne permettent plus  l’écriture depuis pas mal de temps. Pouvez-vous faire quelque chose ?

**Developer response:** More info on write support is available here:
https://disk-decipher.app/write-support/#storage-provider

Dropbox (used as remote disk) never had write support, due to API limitations. pCloud used to have write support, but pCloud removed that capability from their API in 2025, more info on that here: https://disk-decipher.app/remote-storage/#pcloud

You might want to install the Dropbox app and access your disk as Linked Disk, as described in this example: https://disk-decipher.app/disk-types/#example

That will allow write access.

### 5/5 — One of my favorite apps

*2026-04-26, version 6.5.0*

It will be greater if it has built in slideshow functionality.

### 1/5 — 更新后闪退打不开

*2026-03-26*

请您修复一下 更新后闪退打不开

**Developer response:** We fixed a crash reported on iOS 16 in version 6.4.9. Please update your app and retry.

If the issue persists then please report the crash as described here: https://disk-decipher.app/contact/#crash-report

### 5/5 — The best by far

*2026-03-24*

The best disk/volume encryption solution for iOS. The developer is very engaged and responsive.

### 5/5 — Thanks

*2026-03-01*

This is so cool

### 3/5 — Hidden Purchase

*2026-02-24*

It doesn’t tell you before you buy the app that once you buy the app, if you want to write anything to your encrypted volume you have to pay to unlock filesystems.

I added one more star because I found if I expand the information there is text that explains file systems are an extra purchase, but there is no information to make a decision such as cost. In Australia it is $12 AUD to unlock all the filesystems.

**Developer response:** The cost information is available on the App Store in the usual place: just expand the "In-App Purchases" section and the exact amount will be shown. As this amount depends on currency/location, we cannot include it in the app description.

Note that the support site has more details on this subject: https://disk-decipher.app/filesystems/

### 5/5 — Works but…..

*2026-02-07, version 6.4.0*

I had some issues at first but got it to work however when I went to disk-decipher.app/contact for help there is no way to contact anyone. I don’t want to have to join Reddit just to get help. If someone needs help we should have access to a valid contact.
