Kudos to the developer. It really is the right thing to do when services shut down.

You’ll need to set it up locally and can then access it via browser (since it has a mobile view). There’s no more mobile apps since they went open source, as it’s just too difficult to maintain them. To get you started, check out https://actualbudget.org/docs/install/ :)

And with the latest update, adding transactions via mobile in Actual has been added, too :)
