About UnisonSync

UnisonSync brings the Unison File Synchronizer - a powerful cross-platform file synchronization tool - to Android!

UnisonSync allows you to use Unison without having to use it from the command line. Root is not required.

Unison is a powerful cross-platform file synchronization tool available on Linux, OS X, Windows, etc. Unison takes two roots, that can be on different machines and can be modified separately, and brings them up to date by smartly propagating the changes between the roots.

The key features of Unison are:
- Synchronization between different platforms
- Handles simultaneous updates to both roots
- Smart and safe: Unison resolves most simultaneous changes on both roots automatically, and prompts the user for input if it cannot determine the copy to propagate
- Synchronization to a server over SSH: any machine with an SSH server and Unison can act as server
- Resilient: handles interruptions, network disconnections, etc.
- Bandwidth efficient: the data is transfered by a compressed protocol similar to rsync, and only modified files (or parts of files) are transferred.

As an Android application, UnisonSync hides all the complexities of using Unison on the command line.
UnisonSync allows:
- to generate the public/private keys (using the included OpenSSH) to allow the Android device to connect to the SSH server against which you want .
- to configure the roots and unison parameters (fully manually configurable as well; one profile or synchronization directory at a time only).
- to launch the synchronization (which requires a button press! hint to Tasker users). Synchronization then happens in the background as an Android service. Once the synchronization is over or if user input is needed a notification pops up.
- to browse through Unison's command line output

NOTES:
- Only for ARM devices

What are users saying about UnisonSync

C70%
by C####:

Even upon first install and setting up everything perfectly, it bombs with a lock file error. Which is impossible to remove on non-rooted devices running android 6. Beyond this, the UI is very basic and limited, as others have noted. To add insult to injury, I was unable to get a second refund because I refunded once and rebought in a short time to try again.

G70%
by G####:

Stay well clear doesn't run on Android 6.01 on a Nexus7, referencing files that don't exist. The author also doesn't appear to be around either :-(

T70%
by T####:

UI is way too primitive, functions too limited, no way to preview before syncing and no option to sync local dirs. Nice idea, but you've got a long way to go before arriving where this needs to be.

T70%
by T####:

usable, if you already know unison but be careful, the ocaml version used to compile unison on the server has to be the same as on android it's not good enough to have the same unison version my first unison version on my server was compiled with the latest stable unison version 4.x and I got constantly errors they vanished with an ocaml 3.x version used for my unison on server side please detect and remove stale locks within the gui, or you have to use -ingnorelocks, not a sane default for everyday use perfect, if I'm able to use more than only *one* profile

T70%
by T####:

I was expecting the ability to set up multiple profiles for different directories (like in 'rsync backup for Android'). But apparently it allows only a single account to be set up an run at a time. Am I missing something here?

T70%
by T####:

The opposite of self-explaining.

N70%
by N####:

I have been generally happy with the app. However I updated to Android 6.0 recently and it is no longer working. It throws an error about a locked archive file, which as far as I can tell, does not exist.

M70%
by M####:

Unfortunately, I think the intentions were in the right place, but one must know how to decode most of Unison's options as command line arguments to the program and supply those in the "GUI interface". The biggest drawback is the lack of profiles. Using the command line version of the program, it may be possible to use profiles, but this version does not allow for such. Moreover, it would seem if GUI version were simply designed to create "a profile" from the setup screen as opposed to creating each element to pass as a command line argument, this would have been a much easier task to implement. Have tested using multiple paths, multiple ignore paths, ssh to a specified port, and using a key, and the program does work; so at least there is that. Unfortunately, the interface could use a serious overhaul.

H70%
by H####:

After the last update I forgot to generate/update new keys. Afterwards it is working perfectly fine. The one profile could be improved but if you want to sync your files without sharing them with any other service/server and keep your private files really private, then this is the way to go.

Y70%
by Y####:

Thanks for creating this. Couldn't find proper place for reporting bugs. Loses output on rotation and screen blanking which is a bit annoying but not a showstopper. Automatically creating and sharing the key would be handy. Had issues with "Uncaught exception Sys_blocked_io". See https://alliance.seas.upenn.edu/~bcpierce/wiki/?n=Main.UnisonFAQTroubleshooting in older version.

Q70%
by Q####:

Works well, but is crippled by its inability to create multiple profiles. This should be an easy fix, since it's built in to unison itself. If this changes, I'll change my rating to five stars. $6 is rather pricey for an app without this feature, especially considering that this app *doesn't* reproduce the lovely item-by-item conflict resolution of the desktop GUI.

The configuration is somewhat messy but that is a unison problem. You do need to know how to configure the far end to handle the ssh authentication, but I would assume that anyone running unison could do that. Having got it working I didn't want to alter anything, but is it/would it be possible to use a standard .prf file for the config?

Crashed on launch.
