tinyCalc is a custom calculator app & widget for iPhone & iPad. Full-featured, yet simple. tinyCalc allows you to see all of your functions- no need to rotate your phone to get to everything, and the minimalistic design lets you focus on what matters. Widgets should be compact, but comfortable to use. The tinyCalc widget was designed with this in mind. Collapse into compact mode or show the entire calculator. You can even customize the buttons in the app, and your configuration will sync with the widget. From students to professionals, tinyCalc is the calculator for everybody. "This custom calculator has a lot going for it." -AppAdvice User testimonials: "tinyCalc is fast [...] almost every calculator I've ever tried for my iPhone or iPad has been slow as molasses." "I have an iPhone 6 plus and I love [having] the calculator on the lower half of the screen which makes it easy to use with one hand." "Great for most purposes. Love the widget function!" Features: - widget works without even unlocking your device on iPhone and iPad - all standard scientific calculator functions - customize buttons- press and hold to enable drag and drop - open app from anywhere by tapping the top area of the widget - copy/paste the currently typed number - shake to undo in the app - now with easter eggs... - settings include: > degree/radian modes and optional animations > 8 great themes > move the numpad to the bottom to make tinyCalc more like traditional calculators Please note: tinyCalc is a simple, single-step/immediate execution calculator. You will have to keep this in mind to preserve order of operations (ex. 1+2*3 = 9, but 3*2+1 = 7). The one exception is the '%' function, which allows for tip calculation (ex. 100 + 20% = 120). We are considering adding an option for formula calculation in the future! If you love tinyCalc, we would love if you left a good review. We'll never bother you to do so with pop-ups or ads while you're using the app! tinyCalc is made by DiNiCo, an independent software company in Boston, MA, USA. Follow us on Twitter at @tinyCalc, and let us know if you have questions or concerns! If you find any issues, we'll aim to fix them in the next update! Thanks for downloading our app!
