Ratings and Reviews
Great but persistent issue
Love the utility, but… Over time, reading and writing to linked vc disk, Documents and Data storage/internal app storage explodes from ~5MB to ~1GB. No data should be being accumulated in internal storage. If this bug is hard to reproduce, would a full app reset option be possible that allowed for the app internal storage to be cleared as opposed to having to reinstall the app all the time. Also deleting and reinstalling the app does not clear previous disk entries either for some reason which seems a privacy issue (but maybe iOS related?) so this might be something fixable as well.
Update Nov 2022:
Still a great application. But would be nice to have an option to keep disks mounted while switching between apps and to only unmount disks after a certain time threshold or when the app is swiped away and/or having an iOS shortcut integration allowing user initiated ejection. I realize iOS limits what is possible and volume integrity and key safety are important factors, but it can be extremely time consuming and frustrating to have to remount disks if you suddenly need to use another app while managing a volume.
Developer Response ,
Thanks for your feedback! Please contact me https://disk-decipher.app/contact/ so we can investigate the disk usage issue.
The disk entries are stored in the iOS keychain for extra security, which is why they are retained on app re-install.
As for the automatic unmount: if you enable the passcode lock in the settings, you will get the option to keep the disk mounted (for a configurable amount of time).
one of the few
One of the few pieces of software I’ve found that can reliably handle Truecrypt & Veracrypt files over Apple IOS. Worked on my Ipad 3 and still working on the 2018 Ipad. Still getting udates as well, I see. Nice.👍👍
An invaluable app for accessing confidential data securely
After a number of years development, this is now quite an exceptional app. It provides a complete solution to the issue of carrying and using confidential files on the iOS platform. Previous limitations imposed by the amount of RAM available are no longer relevant and the range of applications for the app have as a consequence expanded. Previously, the only way that large encrypted files could be utilised in a mobile environment would be to use a laptop as a viewer.
The creation of encrypted containers still requires the use of say, Veracrypt or the now obsolete Truecrypt running on a desktop or laptop, but the freedom to be able to so easily carry and access files whilst still meeting data protection legislation requirements is highly liberating and incredibly useful. I cannot overstate how valuable I find it is.
