Yes! Just note that the total ISA contribution limit is £20,000 per tax year, and this limit is shared between all ISAs you hold.

The limit for the Lifetime ISA specifically is £4,000 per tax year, so if you contribute the maximum in a single tax year, this leaves you with £16,000 of your annual allowance remaining to contribute to other ISAs, should you wish.

Within Moneybox, you can contribute to an ISA and Lifetime ISA in the same financial year in the same app.
