MinusPlus: Infinite Canvas Calculator - Paste, Enter, Done

Hey PH! 👋 I'm Biswajit, solo dev of MinusPlus (minusplus.app).
This started as my hack for SAP number crunches:
Just type a number, hit enter ↵, add another number - see the result. No need for (+ symbol)

Or copy from database tables/spreadsheets, paste anywhere, and get the result.

The Magic

Imagine a calculator that's not trapped in a tiny box, it's an infinite digital canvas where you can jot down lists of numbers by pressing "Enter ↵" or "Space ⎵" anywhere. And instantly you get the result.
No more scrolling through history or fighting cramped interfaces.
Just pure, fluid math on a beautiful, distraction-free space.

Offline, ad-free, private.

Why It Rocks

Ditched clunky calcs for fluid math. Battle-tested on SAP/Accounting chaos- now yours. (Pro tip: There are keyboard shortcuts, which are super Addictive!)

Key Wins:

- Paste & Sum: Copy-paste numbers in columns anywhere, see the total instantly

- Infinite Space: No limits, no history scroll.

- Offline Joy: Works forever, zero tracking.

- Mobile/Desktop: Feels native.
