All in One Calculator

Thank you for using aio Calculator. It's regularly improved and modernized to better serve you. Recent changes include: • Paste to Calculator is back in the Unit Converter's unit menu. • In degree mode, cos(90°) now shows 0 instead of a tiny number like 6.1e-17, and other right angles are exact too. • tan(0) and tan(180°) no longer show an error. • RPN: after swiping a stack row to Clear or Delete it, the row can be swiped again right away. • Programmer: pasting an expression such as 123 + 321 = into a row now enters its result. • The Unit Converter grid no longer flickers when the device is rotated. • The Unit Converter's Feet Inch unit shows its value again, such as 8 ft 2.4 in. • Touching and holding a measurement in the Unit Converter's list shows its menu again. • Speed / Velocity adds Inch/Minute (in/min) and Millimeter/Minute (mm/min). • Unit Converter favorites now sync through iCloud across your iPhone and iPad, and with the Converter of Units app. Sync is on when you're signed in to iCloud; turn it off with Sync via iCloud under Converter Favorites in the app's settings. • History iCloud sync no longer stops after moving to a new iPhone or iPad. If sync is ever paused because the iCloud account changed, the app now says so and offers to resume it. • Accessibility: History comments have a VoiceOver label and grow with larger text, the root keys read as a single button, the sidebar's secondary text and the currency update time are easier to read, and each unit's actions button is easier to tap. • General fixes and improvements.
