LiquiMed is a small calculator app with witch drops can be converted to mililiter.
Apart from the direct calculation this app does much more.
First of all there is the possibility to define the uses per day and calculate the mililiters a day. This is done by a bar at the top that makes it easy to define a 1, 2 or 3 uses per day input.
In addition to that feature the duration of the useage in days could be defined. The result is the total amount of mililiters needed for the hole duration.
The calculation is simply done by pressing somewhere on the result area.
The app will do a recalc in addition to that if the amount of uses per day is changed.
As not all liquid medicines have a constant of 20 drops per mililiter this value could also be changed.
Predefined values with 3 uses a day, 7 days of duration and 20 drops per mililiter make it a perfect app for this use.
