What’s new in version 2.2.0
A dashboard that gets to the point Four tiles first: this month's spending, the projection for the year, active subscriptions, possible savings. Then how your spending evolves over six months or a year, and the findings that matter: the steepest price increase, what to decide this month, what doing nothing would cost, subscriptions untouched for eighteen months. Where your money goes Your spending over a year, by category, in a ring, each share with its amount. Cash flow with its calendar This month's outgoings and what is still to be debited, then a calendar where each due date shows its subscription. Monthly and yearly, apart The list sorts your subscriptions into two sections, and filters at the top show all subscriptions, monthly ones, yearly ones or those to watch. Your subscriptions' logos Custos suggests the service's logo from its name; you accept or remove it. Without a logo, the subscription shows its initial in a black circle. A more telling detail view The total paid since the first payment and the cost over a year, right below the next payment. Categories no longer split in two After an iCloud sync, a category created on two devices keeps a single copy. A safety backup is made first. Easier to read Stronger contrast, and text that follows the size chosen in the system settings. Better-aligned forms Text fields align to the left, and notes are written below their label.

Data and privacy
Your financial data remains yours.
Custos is built from the ground up around absolute privacy. No budget, bank account, subscription, or contact details are collected or shared.
100% local
Your entries reside on your iPhone via SwiftData. No account setup required.
iCloud optional
Syncing across your devices is disabled by default and relies solely on your secure Apple account.
Zero trackers
The app contains no ads, third-party analytics SDKs, or data selling.
We own no servers and run none: the app’s network traffic never goes to us. It comes only from Apple’s services — iCloud when syncing is on, and Apple’s notification service for Live Activities. Those exchanges happen inside your Apple account, under Apple’s terms.
