boldCalc, the calculator app redesigned for the smartwatch.

boldCalc is a reimagined calculator app, designed for use on Fitbit Versa or Ionic smartwatches. boldCalc uses an innovative “drawing grid”. Draw numbers and operators on your wrist, instead of using tiny buttons. You don’t need perfect drawing skills either. boldCalc uses on-device analysis to determine the closest match. All calculations are complete on-device, from drawing recognition to math calculations. Once you download and activate the app to your smartwatch, you don’t need to worry about if your phone is connected or if you have internet access.*

*Internet access is required to install, purchase, and activate the app.

How to use the drawing grid

The centerpiece of boldCalc, the drawing grid, lets you input numbers, the decimal symbol, or operators (+,-,x,/) by simply drawing on the grid. The video below shows how to calculate 2+3 using boldCalc.
