I’ve been doing envelope budgeting for almost a decade and my household only runs smoothly when I can stick to my weekly budgeting update schedule. I’ve been able to use Actual in beta for almost a year with no interruptions to this process. James has been an amazing steward of the product and I’m sure it’s only going to get better over time.
I've followed James' development of this product for a while and he's very talented, competent, and committed to this. I think it's worth trying if you're interested; I suspect it'll be supported for a while yet.
Kudos to James. The product keeps improving with each update.
