  1. 4/5File support fixed! But...

    I’m updating my review for two reasons. #1 is that file support was added, and I can now easily import a LUKS container from iCloud or Nextcloud/ownCloud/etc.. However, I was disappointed to discover, after importing my containers, that they failed to mount. After reading on the website I conclude that there is no support for ext4 formatted containers. Having a journaled FS in my container has saved me from file corruptions on several occasions. On my computers I run fsck on the decrypted volume every time I mount the container, and it’s not uncommon for it to find problems and fix them. You might wan’t to consider added a step like that as well. Not that I’m an expert on any of this, though. At the least, could you please add support for common open-source filesystems, such as ext4? I’ve been patiently waiting and watching as this app evolves, and I was sure it would where I needed it to be for my use-case in this last update... I’d be so grateful if you could make it compatible with containers that house an ext4 filesystems! P.s. I tried to find an email on your website but didn’t see one, the feature request form did not have a place to write in a feature either, only select one of those in the list. Thanks!

  2. 4/5Alright app

    App works fine, but does not have many features. You are unable to create crypts (you must create with 3rd party then import. I used VeraCrypt and sent the file through Google Drive), you are unable to delete directories (folders), you cannot move files around, you cannot search for items (no search bar/function), and you cannot choose how items are sorted (date/alphabetical/size/etc). The app feels a bit restrictive, but it does its job. I’d recommend this app as more of a crypt viewer than a crypt editor. On the plus side, this app’s privacy policy is great, it supports many file types, and it is very secure (the second you close the app it dismounts the drive). Of the two apps for file decryption on the AppStore right now, I would recommend this app. While this app is missing a lot of features, it has a much better privacy policy than the other, and this app does not (to my knowledge) have ties to the Chinese government like the other one. Overall, missing features, but secure. 4/5.

  3. 5/5Handles VeraCrypt volumes, great authentication policies

    There only seems to be two VeraCrypt compatible apps on the iOS App Store, and this seemed to be the more trustworthy of the two. This has no issues mounting and exploring my VeraCrypt volumes. There's also very flexible authentication methods (for example, saved password requiring BOTH your biometric authentication and your iOS passcode). Because of Microsoft licensing there is an extra purchase to access exFAT so I ended up switching one of my volumes to NTFS and have no issues with it. I would absolutely recommend this to anyone needing to browse their VeraCrypt volumes.

  4. 5/5Overall it suits my purpose and recommend to buy

    Overall it suits my purpose. But I hope that this developer makes this app recognize dmg image file lager than 100 gb. It reads and mount about 7-80 gb dmg but can’t do that for any bigger file. I think that the developer willingly limit its readable file size for some reasons. Please fix it.

  5. 5/5This IS a great app with a great developer

    I have had this app for 2 years now, and every time I turn around the developer is making the app better. I mean like actually better, not fumbling around and breaking things to add pointless bells and whistles. This is a small well built app, that does exactly what it is intended to do, help you secure your data in this insecure world on mobile devices. I even contacted the developer once about an issue I had, and the answer and resolution was quick. Kudos to you! Everyone wants to scrape your data out of your hands (both those claiming to do it for good, and those who have an IOU note where their soul was), so do what you can to protect yourself. Will it solve world hunger, probably not, unless a reporter has found a secret stash of food being kept from the poor to prevent an uprising. ;) But it will hopefully protect said reporter’s data a bit.
