Which devices does Calsa work on?

Calsa works on iPhone, Android and the web. Sign in to the same Calsa account to use your synced diary and subscription across devices, so you do not need a separate subscription for each one.

Some phone features need the mobile store app, including Apple Health or Health Connect. A browser can show Health values already brought into your account by the phone app, but cannot establish that connection itself. Entries still waiting on one device are not yet available elsewhere.
