We think that the key to any great app is a beautiful, and simple design that works seamlessly with the app's features. \n\n• Scientific Calculator\n• Voice Calculator\n• History (Swipe down in the display area)\n• Copy and Paste \n• Dynamic Light / Dark Themes (and icons)\n• Larger Buttons Option \n• Available on Apple Watch \n\nMemory Slots\n• Save a value inside one of 11 memory slots to use them in calculations later\n• A value may be the result of a previous calculation, or pasted from the clipboard into a memory slot\n• The process to store a value in a memory slot is very easy and fast, just drag down a memory slot \n• Copy memory slot value to clipboard \n• After having a set of occupied memory slots, you can apply one of six different operations on them in one tap: sum, average, product, median, max, min, of the occupied memory slots. \n\n___________________________________________\n\nTerms & Privacy: https://bit.ly/haseba-terms-privacy\n\nNeed help or have questions?
