Floating Calculator

Pull down Quick Settings, tap the tile, and the calculator floats over whatever you were looking at.
No opening and closing an app.

• Right from the Quick Settings tile — no trip to the home screen
• Floats on top of any app
• Unit price comparison for grocery shopping — see which one is cheaper, and by how much
• Drag the window anywhere, in two sizes
• Long-press a result to copy it

What it does not have:
• No ads
• No account, no sign-in
• No subscriptions, no purchases
• It never asks for internet permission — it structurally cannot send anything

I built it for myself. The app I had used for years disappeared from the store, so I rebuilt it,
and published it in case someone else needs the same thing.
