Here is a UTDESIGN's Fitbit Versa and Ionic Clockface Store.
You can purchase with PayPal or credit card. Please enter 1 (=$1) for the amount (you can donate by entering the amount of money. I would be happy if you donated to me.) and purchase. You can download the text document containing the URL of the download destination. After downloading the document, open the link destination via smartphone and you can install clock face on Versa or Ionic. (If you are using an android smartphone and the link cannot be opened with Google Chrome, access it with another browser such as Firefox.)
How to purchase and Install is here. (sorry, Japanese only.)
