I need to restore my Tomowallet and can't find the app in iphone app store

Why can’t I find the Tomowallet app in the iphone app store? I have an existing Tomowallet that was installed on an old iphone which is no longer working. There are tomochain tokens in the wallet. It has been awhile since I opened the wallet. Now I can’t find any up to date information on getting Tomowallet installed so I can restore it.
