Mettle is still being developed, and so is not available to everyone. However, we are inviting some users to help us make the product as useful as possible for small business owners, freelancers, contractors etc. We call this "Early Access".
This is a stage of the product where user feedback is hugely important for us. If you would like to be one of the first users to open a Mettle account, we would love to hear from you about what you like and dislike. That way, we can build a great experience for you and your business.
Mettle is currently only available by invitation. The Mettle app is available through TestFlight, which is an application provided by Apple to host apps in development. This allows us to give customers 'early access' to test the app before it goes onto the App store.
You can register your interest in an early access account over at https://www.mettle.co.uk
