Paid Non-Client Promotion for the Cash Account: NerdWallet has engaged Atomic Brokerage LLC ("Atomic"), a registered broker-dealer and member of FINRA and SIPC, to bring you the opportunity to open a brokerage account (“Cash Account”) in which cash is swept into unaffiliated bank deposit accounts opened for you by, and in the name of Atomic Brokerage as agent and custodian. NerdWallet is a promoter of Atomic. Atomic shares fees from the cash sweep program banks with NerdWallet for each referred client who opens a Cash account, which creates a conflict of interest. Atomic and NerdWallet are not under common ownership and are not related entities. You will not be charged any fee or incur any additional costs for being referred to Atomic by the Promoter. For more details about Atomic Brokerage, please go to https://www.atomicvest.com/atomicbrokerage. You can check the background of Atomic Brokerage on FINRA’s BrokerCheck at https://brokercheck.finra.org/. See important Cash Account disclosures at https://www.atomicvest.com/legal/disclosures/7d9c31dd-bf97-46ae-9803-1774b97187af. You should not expect cash deposited in an Atomic Brokerage account used solely for the purpose of accessing the Cash Sweep to be protected by SIPC or FDIC insurance, and cash is only protected by FDIC insurance (subject to coverage limits and eligibility requirements) once deposited by Atomic Brokerage in the unaffiliated bank deposit accounts. If you prefer your cash to be invested in a Money Market Fund eligible for SIPC coverage, you must send an email to support-brokerage@atomicvest.com to discuss your options.

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.
