Compatible with iOS 14 to 16.
You should know the pain, when you've downloaded some cool tweak long time ago but then missed its repo or this repo is now inactive, and you'd like to somehow save that tweak which is already installed on your device. That's the problem that solve multiple utilities like Batchomatic, redeb and some others. Twackup is not an exclusion.
Twackup app allows you to view all packages and packages that are not dependencies of others - they are named leaves like in Homebrew project. You can rebuild them back to debs by single or multiple, and store multiple versions of them. Compression type and container are also editable - you can rebuild debs to gzip or zstd archived, for example. Every built deb can be shared or removed from the storage. You can also export the list of leaves packages, e.g. to share them with your friends. Some features introduced in CLI version are not supported - repositories management and packages importing are examples of them, but I think I add them a bit later.
Twackup GUI is supported on iOS 14 and later and have possibly support on rootless jailbreaks like Xina, but I'm not sure about rebuilt debs' validity.
Twackup is open-sourced
