What’s the best Crypto tax software in the UK?

Hi all, not sure if this is the right place to ask and hoping I can get some help.

I'm looking for recommendations on the best crypto tax software I can use to report capital gains tax in the UK. Seeing that the UK have reduced the tax free threshold to £3k it looks like reporting gains is inevitable especially if I decide to sell now whilst the market is up. The CGT percentage is also increasing from the new tax year so will contribute heavily to my decision to sell but need a software that can help me see the unrealised gains so far as well as prepare a tax report if I need to file my taxes.

Any recommendations and feedback from people that have used these types of software will be greatly appreciated.
