Duome

Two people, one shared ledger. One of you logs it, the other sees it right away — no accounts, no invites, just iCloud.

A budget app for couples who share money. Open it on either phone and you're looking at the same book. One of you logs a coffee, it shows up on the other's screen seconds later.

■ Logging takes 15 seconds How much, what for, who paid. Three taps and you're done — on the way out of the store, right after the subscription charge hits.

■ It syncs while you're still putting your phone away iCloud keeps both devices in step. No sign-up, no invite codes. If you both have an Apple Account, you're already connected.

■ Your money, their money, our money Just tag who paid. Shared and personal spending get split automatically, so nobody's digging through receipts at the end of the month asking "wait, who covered that?"

■ You set the budget, the app fills it in Set a limit per category and the numbers pile up on their own. You'll see exactly where this month is leaking.

■ The whole month, right when you open it Total spending, category breakdown, latest entries — all on the first screen.
