Left. is the budget app that answers the only question that matters. No bank login. No subscription. Nothing leaves your iPhone.
The whole idea
Set your income. Add your bills. Start each month with a full ring. As you spend, it depletes. The big number under the ring updates the moment you log a transaction. That's the app.
Free, for everyone
No paywall on the parts that matter. Download Left. and you get the whole budget, built for the way you actually live.
Ask anything in plain English. Answers come from your own numbers, computed on your iPhone. Nothing sent to a server, ever.
Available on iPhone 15 Pro and later·Free for everyone
Inside the app
A complete look at the app, the widget, and the Apple Watch companion.
Private by design
Everything in Left. runs on your device. iCloud sync between your devices uses Apple's end-to-end encryption. Even we can't see your data.
Compare that with bank-linked budget apps, and the credentials they ask you to hand over.
Built for Apple
Built in Swift, designed for iPhone first. No web wrappers. No cross-platform compromises.
Pro
Left. is free. Pro just goes deeper, for the people who want to model their full financial picture, not just their month.
One-time purchase·No subscription·Family Sharing eligible
No monthly fee. No data harvesting. Just the number you came for. Free to download. Yours forever.
