Pro-tip: Don't use software by companies who explicitly hate cross-platform software when you need said software to work cross-platform.
For credentials/secrets, there are other tools that actually does a really decent job at being cross-platform (including iOS/Android). Two of these are 1Password and BitWarden (FOSS as well). I'm a happy user of the former, but lots of people (including many here on HN) sing praise about the latter.
