Built by a reseller who got tired of paying monthly for something a phone can already do. Every background remover I tried was a subscription to an online service: upload each photo, watch a credit balance tick down, wait on the connection, and hand my product photos to someone else's servers.
StudioDrop is the opposite. It uses Apple's own on-device machine learning, so nothing is uploaded, nothing is metered, and it works with no internet at all. It's the tool I wanted for my own listings โ fast enough for a hundred photos in a sitting, private by design, and paid for exactly once.
