Calcula Keyboard vs Scrolly

Calcula is a lightweight scientific math keyboard for iPhone. After you add the keyboard, you can type expressions in chats, notes, browser search bars, or any system text field, and insert the result at the current cursor position. Version 1.0 focuses on the core workflow: a basic keyboard, an f(x) scientific panel, DEG / RAD trigonometric input, in-keyboard history, and a companion app for setup guidance, basic settings, and About. It does not include accounts, cloud sync, or online computation. Settings stay on the device.
