I host for my family which has a mix of Android and iPhone. So far, no complaints about Bitwarden on iOS. Hopefully it works out for you. If self hosting becomes a problem, I think premium is only $10/year and family is up to 6 people at $40/year.
Vaultwarden is what I use: https://github.com/dani-garcia/vaultwarden/
Their wiki is pretty good assuming you’re comfortable with Docker.
Back before I self-hosted, KeePassXC for desktop and Keepass2Android for mobile (along with Synching to sync the database) got the job done.
I have the same setup with Firefox and Bitwarden without issue. Do you happen to have Firefox setup for restricted battery usage? Android can be quite aggressive with that.
Cloudflare if they have the TLD you want/need (their pricing has no markup). There’s also Namecheap and Porkbun. Sometimes they have sales that can make it cheaper.
Belter slingshot racers know this all too well. NOTE: Spoiler for an episode in the Expanse which everyone should watch if they haven’t already.
