That's what I use as well. Nice apps, fair pricing (One-time payment) and no data collection. Started using it only because of its feature to sync between devices with iCloud - so no more stress if my phone breaks.
Unfortunately it has no import/export functionality and truncates eight/ten-digit TOTP codes. As I mentioned in an another comment, even then it is better than most alternatives on iOS.
For me there’s an export option under „Settings“ ->„iCloud“ ? Or do you mean something different?
