Consumer lender Wisr has entered the "financial wellness" market, with the launch of an app that rounds up purchase amounts and allocates the amount to payment of a debt.The Wisr App links to a user's transaction account, rounding up purchase amounts to the nearest dollar. That amount can go to a credit card or mortgage debt "held with any financial institution in Australia", Wisr says.The app also has a "booster feature", which allows users to make extra contributions of up to A$25 to their debts.Users can suspend round-ups at any time. The app costs $1.25 a month to use.Wisr says the app was downloaded by 4000 users during its trial phase. After what it says was a positive response, the app has been released for iOS through the App Store. The Android version is in development.
