2. Tap Apple One.
3. Choose a plan.
4. If you already subscribe to Apple Music, Apple News+, Apple Arcade, or Apple TV+, you don't need to cancel those subscriptions. They will automatically be canceled when you're billed for Apple One.

If I remember correctly, the $19.95/month Apple One plan includes 50 GB of iCloud+ storage. This is the same as with the cheapest ($0.99/month) iCloud+ plan.

I believe you can go up to a $25.95/month Apple One Family Plan to get 200 GB of iCloud+ storage – or you could stick with the $19.95/month Apple One plan and combine it with a separate $2.99/month iCloud+ plan (cheaper).

FY, it also looks like Fitness+ is part of the $37.95/month Premier plan – not part of the $19.95/month Individual plan or the $25.95/month Family plan.
