"Use as Ringtone" isn't in the share menu
That option arrived in iOS 26. Check Settings › General › About. On iOS 18 or earlier, tap Set and choose GarageBand; Ringtonius shows the three steps. More in this guide.
A song won't open
Songs downloaded from Apple Music are copy-protected, and iOS doesn't allow them as ringtones. Use a song file you own, a video, or a voice memo.
Where are my tones?
In the app under Your tones, and in the Files app under On My iPhone › Ringtonius.
Restore a purchase
Open the app, tap Pro, then Restore. Use the same Apple ID you bought with.
