Daily number first
Open Basin and see exactly what is safe to spend today.
iPhone budget app
Basin is an iPhone budgeting app that consolidates income, bills, subscriptions, goals, and everyday spending in real time into one safe-to-spend number.
The app experience
The daily number updates as money moves, so today stays clear without forcing you through a spreadsheet, category maze, or guilt dashboard.

Real product surfaces
From quick logging to vaults and insights, Basin keeps the interface calm, tactile, and direct.

Open Basin and see exactly what is safe to spend today.
The Basin system
The app keeps the surface simple while the system protects the boring-but-important money before you see what is safe to spend.
Add your paycheck, variable income, or starting balance.
Subscriptions, rent, savings, and vaults are protected first.
What remains becomes a clean daily number you can trust.
What it keeps calm
Every surface borrows from the app: quiet glass, tactile borders, clear hierarchy, and the ring as the default visual language.
Basin turns income, bills, savings, and rollover into a single safe-to-spend limit for today.
Fixed expenses and savings targets are removed before spending money is shown, so the number is honest.
Spend less today and tomorrow can breathe. Overspend and Basin smooths the adjustment forward.
Keep short-term savings separate from daily spending without building a spreadsheet around them.
Add detail when it helps, but keep the home screen anchored to the number you actually need.
Basin is designed around device-first budgeting, with connected features kept optional.
Privacy and price
Basin is a local-first iOS budget app, with optional connected workflows kept opt-in. Basin Pro is planned at $3.99 USD per month, with storefront pricing varying by region.
