These are accounts where you can only access your money digitally (either via the internet or an app). Money at call which means you can get money whenever you need it and earns variable interest (bank pays you for lending them your money).
When choosing an online saver, look out for accounts with no fees, higher interest rates and be careful of fine print “honeymoon” or “introductory” rates which only last for a few months.
