I have had a good experience with Keepass2Android. It has support for databases on Google Drive.
Thanks, I actually use Keepassdroid. However, can it open databases from KeePassXC? (Well, I guess I can check a bit later myself.)
I use MiniKeePass on iOS and have been very happy with it.
For standard keepass I use keepass2android and nextcloud for syncing. That said I don't believe it supports any of the fun new stuff from KeepassXC. It does work with NFC and HOTP though. I'd love to use TOTP instead.
Thumbs up for Keepass2Android. Extra two thumbs up since it provides also a version without network capabilities for additional peace of mind, I found that a great touch.
