RackHut
iOS app — inventory, profit and postage for resellers, on the App Store
A native iPhone app for UK and EU resellers: what's in the rack, what it cost, what it sold for, what's left to post — with an append-only ledger underneath so any number can always be explained.

01
the problem
Resellers run a business from a marketplace app and a notebook. Profit is a guess, postage gets forgotten, and any tool that imports history must never silently rewrite it.
02
the engineering
Native Swift. An append-only ledger with revisioned migrations and integrity checks, so an undo is a real inverse and imported stock is real stock.
Scan a sale from a screenshot; bring in a shop; a to-ship bench; monthly milestones. Spotlight and Siri surfaces, a paywall that honours accessibility sizes, StoreKit purchases. Real-data walks reproduced on the actual ledger before each build.
03
the proof
3,341 test cases across 337 test files; 1,018 Swift files, 172,940 lines.
1.0.0 live on the App Store; 1.1.0 built, walked on device, and in App Review.
