What's New in KaiJar
1.3.0
August 21, 2026
Penny Budget is now KaiJar. Same app, same person building it, and your data is exactly as you left it. If the icon on your home screen looks different this morning, that is why — nothing has been taken over. Every transaction, budget, card, savings goal and category is exactly where it was. You do not need to sign in again, re-import a statement, or re-share your household — the sharing code you already gave someone still works. Why: there were a dozen or more apps called some version of "Penny Budget", and being impossible to find in a search is a bad problem for an app you open every day. KaiJar is ours alone. The new icon is a jar filling up with coins, which is closer to what the app actually does than a piggy bank was. ALSO NEW IN THIS UPDATE • Pay for something straight out of a fund. Pick the fund on a transaction and the withdrawal is filed for you — no re-typing the same amount on another screen. You see what the fund will be left with before you save, and deleting or refunding the charge puts the money back. • The Budget screen now stops you before an edit assigns more than the month's income, tells you by how much, and offers a way out.
