American Family Insurance used to offer an app for this called DreamVault (https://appadvice.com/app/dreamvault/536354802). They discontinued it in 2016 shortly after I put my whole house inventory into it of course. It had enough features to make it useful but wasn't very impressive overall. There may be some perverse incentives in NOT having this service for home insurers. If you don't have a good home inventory, they can pay a reduce reimbursement amount.
