I have android and have been using ffxiv app since launch, I have several of them on my phone, not sure why you couldnt find any.

The one I like the best has a widget that displays current time, moon phase and gaurdian day, by clicking on it it will display guildleve reset time. This app is called "Eorzea Clock"

Also have an app called "FFXIV Server Status" it shows server status lol
And my third one is called "FFXIV Guide" It has recipe lists, item lists, etc.
