Yes—Radish gives a two-iPhone household one shared, receipt-based grocery spending view.
Receipt changes can sync through a private iCloud household after an explicit QR invite. Both iPhones can see shared saved receipts, reviewed categories, monthly totals, and the household’s essential or optional choices.

In the US, two separate subscriptions cost $9.98/month or $79.98/year in total. If Apple Family Sharing grants access to both iPhones, one subscription costs $4.99/month or $39.99/year. In the UK, two separate subscriptions cost £9.98/month or £79.98/year; eligible Apple Family Sharing can cover both iPhones with one £4.99/month or £39.99/year subscription.
