The general idea of KeePassium is that you always have full access to your data, regardless of the version.
The free version has a few limitations:
These limitations are intended to be almost invisible for casual users. Beginners will only need a single database anyway, and will have no problem entering the master password once in a while.
For expert users, however, entering a long passphrase several times a day will soon become inefficient. Upgrading the the paid version will enable you to keep the database open longer, and thus save you time and efforts.
The paid version removes the limitations of the free app: you can add multiple databases, quickly switch between them, and keep them open as long as you like.
KeePassium has several paid options. Functionally, they are exactly the same. The difference is whether this is a single or repeating payment, and whether the license covers only you or your family members, too.
Both Premium and Pro work with App Store Family Sharing program. That is, family members linked to your Apple ID account will be able to download the app for free.
If you are just starting and not sure if KeePass/KeePassium works for you — start with the free version.
If you like KeePassium and want to keep it fresh and shiny — get Premium.
If you prefer a lifetime license, even at higher cost — consider buying KeePassium Pro.
If you are buying for business (via Apple Business Manager/Volume Purchase Program), KeePassium Pro is the best choice for full functionality.
