The best and most accurate sample size estimation android app-- and it's free. Being in clinical research industry, I have experience of various softwares like SAS, PASS, STATA, etc. for sample size estimation. This application gives very accurate results given that you should know what you are doing and what you want to achieve. If you have clear understanding of your research designs, objective and parameters, then from my experience I can vouch that numbers given by this app will be very precise.
Works fine This appears to work OK. It would be greatly improved if the 'help' provided an explanation of the terms used and / or these were explained in a pop-up window
Nice A nice app for doing a quick sample size check on the fly. Future improvements would be to add a range of values for a particular parameter and also some nice graphs showing, for example, n vs power.
Nice piece of kit ... If you need to calculate a sample size on the move!
just what i needed a great app!
Very good One of the best apps I have ever seen very very useful!
