Stack - Simple Debt Manager

The fastest debt manager app

Free · In-App Purchases

Stack is the fastest debt management app for iPhone, iPad, Apple Watch and Mac. It enables you to categorize your credit and debt, and conveniently track and manage your finances across multiple devices. Stack offers the following features: • Spaces: Create multiple Spaces to categorize your debt. For example, you can create a Space for each friend who owes you money. • Add Credit or Debt: In a Space, adding credit or debt is easy, requiring only one tap. For every entry, you can choose the name, the quantity and the value. The value can be positive (you receive) or negative (you owe). Entries in Spaces can be sorted by date, value or name. • Remove Debt: Removing debt is also straightforward. Tap on the circle on the left side of a debt entry to remove it. If you accidentally removed an entry, you can restore it later, similar to the Reminders app. • Share Debt: You can choose to share the debt of a Space, which generates a list of all debt and the total sum. You can choose if you want to include entries previously marked as complete, and you can choose to include the date of the entry. The date can also be edited. • Value Calculator: You can use the integrated calculator to perform complex calculations and then transfer them directly to the value field. • Split Sum: With this feature, sharing expenses is easy. Just choose the amount of parts you want to split the sum of a Space, and Stack will automatically calculate the amount of each part. • App Lock: Stack offers Face ID or Touch ID to lock the app, ensuring that only you can access it. • Apple Watch App: You can view, edit, and add new debt on your Apple Watch. A phone connection is not required. • iCloud Sync: All your data is synced between your iPhone, iPad, Apple Watch and Mac. • Privacy: Your data is exclusively stored on your device and iCloud account. The app does not collect any user data, and the developer has no access to it. • Text Field Sizes: You can adjust the name field and the value field sizes to your preference.
