Spiir is a personal finance app provided by Mastercard OB Services Europe A/S, a licensed account information service provider in Denmark. The free service helps users bring accounts together in one place, automatically categorize transactions, and see where their money goes. It offers spending summaries and insights into habits, along with interactive quizzes and weekly overviews.

Users can also set savings challenges focused on areas such as groceries, shopping, and other expenses. Spiir connects securely to bank accounts through Mastercard OB Services; the company says connections are encrypted and users’ banking login details are not visible to Spiir. The service does not sell users’ data, according to its website.

Spiir also provides support articles and customer assistance, plus options to export transaction or personal data in CSV, JSON, or ZIP formats. Spiir has announced that it will close on June 8, 2026. Until then, users can continue using the app and may download information they wish to keep
