This 'Get Sample Size' is a free and simple mobile application that you can use to determine the sample size for your research studies with ease.
The app is based on two formulas that are well known and applied in arriving at a sample size especially when the sample is to be selected from a population of people.

If you know the population size or a sampling frame is available this app will calculate your sample size for you within seconds.
Even if your population size is unknown this app has got you covered. All you have to do is to select a confidence level and indicate the margin of error you would like to tolerate and this app will get the sample size calculation done for you.
