FlexoCalculator vs GARDCO Viscosity Calc
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
FlexoCalculator
This tool assists flexo prepress operators with essential calculations for screen dimensions, minimum print effects, and plate compression distortion. It also handles unit conversions between metric and imperial standards, offering a consolidated solution for prepress needs.
- Calculate screen dimensions in microns
- Assess minimum print effects ('dipping')
- Determine plate compression distortion
- Convert metric to imperial units
- Convert imperial to metric units
- Brand-free and customizable

FlexoCalculator was born from the need to aggregate into a single iOS native tool, many useful features for flexo prepress operators. FlexoCalculator lets you to calculate your screen dimension in microns, to let you know if your printed minimum will be affected by "dipping", if and how much the plate compressione will distort your prints. Flexocalculator will let you convert units from metric to imperial standards and viceversa. The benefits of using FlexoCalculator are: it is a unique tool for all your computing and conversion needs, is brand free, could be tailored to your specific implementation requests.
GARDCO Viscosity Calc
Calculate kinematic viscosity or drain time for various viscosity cups. Input a known value and cup type to find the unknown, with visual indicators for valid measurement ranges. Helps select the appropriate cup for accurate testing.
- Calculate kinematic viscosity
- Calculate drain time
- Support for Gardco and BYK cups
- Input drain time or viscosity
- Visual range indicators
- Error messages for out-of-range values

Quickly and Easily calculate the kinematic viscosity or drain time of your Gardco or BYK viscosity cups. To Use: Input either a drain time or viscosity into one of the given input fields then select the type of viscosity cup you are working with to calculate the viscosity or drain time of your sample. If the selected cup is highlighted in green that means you are within the cups viscosity range and the number is valid. If you are outside of the cups range an error message will appear, meaning you are outside the tolerance range of that given cup. If this appears please use a different sized cup that would be in range for what you would like to test. You can see what cups are in range for your desired value by inputting the value you want to test and scrolling through the list, any cup in green will be able to provide a valid measurement for the desired input.
