We created boosters to help you smash your goals even sooner. A booster is an extra contribution to your weekly round ups. You can add a booster any time. From the homepage, select the 'Add a Booster' button and use the slider to choose your booster amount. Once you hit go, well add this amount to your next round up debit. Keep in mind, it may take a few minutes to show up on the homepage and on your transactions list.
