What Practitioners Say
Fantastic for easy data collection!
" I am so impressed with this tool, it is easy to use and train on and has a lot more flexibility in terms of types of data than most applications. I manage a severe behavior program and it has been great for collecting data even in somewhat escalated situations. My trainees from a local university have commented that they like it too! "
