Stack is the fastest debt management app for iPhone, iPad, Apple Watch and Mac. It enables you to categorize money you are owed and money you owe, 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 Entries: Add an entry to a Space with one tap. Give each entry a name, quantity, and value. Use a positive value for money you are owed and a negative value for money 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 number of parts you want to split a Space's total into, 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 entries on your Apple Watch. No connection to your iPhone is required. • iCloud Sync: All your data is synced between your iPhone, iPad, Apple Watch and Mac. • Privacy: Your data is stored only on your device and in iCloud. 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.

Verdict

The call

The clearest difference is monetization model: Stack at free against Flowt's freemium. Stack also leads on device support (4 vs 2). Flowt's advantage is update cadence (every 8 days vs every 6 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.
