Calcula Keyboard vs ViewSide Link

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.

ViewSide Link connects two smartphones so you can view the camera feed from one device on the other in real time. Easily check workout posture, back and shoulder movement, hard-to-see areas such as under a vehicle or furniture, and small text that is difficult to view on your own. One device works as the camera, while the other works as the viewer. You can connect the two devices quickly by scanning a QR code, with no account or login required.
