It's up to you. Some customers use the app to handle all of their business, while others use it as a secondary account.

Remember, we do have certain limits at this stage – such as a £10,000 outgoing payment limit. If you routinely exceed these, we'd recommend using another account at the same time.

The more you use it, the more useful our features will become. We're working hard to make Mettle even better so we'd love to hear your feedback on how we can improve our features and functionality.

Drop us a line and let us know how we're doing. You can contact us via our in-app or through support@mettle.co.uk.
