The Left. Overview screen for August 2026: a green ring around $1,788 left to spend of $6,500 income, $4,601.97 spent this month, three bills due within five days, and a pace of about $51.85 a day.

The whole idea

How much can I spend today?

Set your income. Add your bills. Start each month with a full ring. As you spend, it depletes, and the big number updates the moment you log a transaction. Underneath, Pace shows what you're averaging a day and where that lands you on the last of the month. That's the app.

Private by design

Nothing leaves your iPhone.

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.

No account No sign-up, no email, no password. Open the app and start using it.
No cloud servers Nothing of yours sits on our infrastructure. There isn't any to sit on.
No analytics, no tracking We don't measure your behavior. We don't know your habits. We don't want to.

Compare that with bank-linked budget apps, and the credentials they ask you to hand over. Read the full privacy policy.
