What you get
Built like a vault. Used like a notepad.
Three principles. Zero compromises. Every feature respects the boundary between you and the rest of the internet.
Smart Receipt Scanner
Snap a picture. Let the on-device AI extract the amount and categorize it instantly. Zero cloud processing.
Flow Premium
Optional upgrade: year analytics, smart slip rules, custom categories, CSV export, and iCloud sync. Monthly, yearly, or lifetime—manage subscriptions in Apple Settings.
How it works
From receipt to ledger—without the cloud.
Three steps. All on your iPhone. No pipeline to our servers, because we don't run any.
Data never touches our servers
Capture
On-device
Your device
01
Capture
Log spends or snap a receipt. Images and entries never leave your phone for processing.
02
On-device intelligence
Amounts and categories are interpreted on your iPhone—the same way we’d want our own bank details handled.
03
Sync when you want
Your ledger lives on-device first. Flow Premium adds iCloud sync across your Apple devices via CloudKit—we never run a server.
The difference
Not another finance SaaS.
Flow is built for people who are done renting access to their own numbers.

Your ledger. Your rules.
Get Flow on the App Store and keep every transaction where it belongs—with you.
