“What a way to make my week tremendously productive. End of the day, last day of the week, I do a quick search to see if there are any random templates lying around for capturing testing notes and stumbled onto your Data Logger. It truly IS the best thing since sliced bread. Now I can forge ahead and get the tasks ready. I'll be singing your praises for a long time...”

What people say

“We have been using the Datalogger in our usability lab for over a year now. It is a great tool for capturing metrics and observations. We use it in conjunction with Morae to capture all necessary data from our test sessions.” — BH, USA

“Datalogger makes it easy to capture performance and satisfaction metrics, and observer comments. The resulting graphs are great for inclusion in a test summary document.” — JK, Canada

“It's really useful to have all the observation notes from the test organised in one place and Datalogger makes it easy to collate notes per task across sessions.” — UG, Sweden

“Datalogger saved us from having to write our own tool to capture metrics information. We have now standardized on Datalogger and have trained our observers on its use.” — GS, Germany

“We were comparing human performance times with mouse vs. keyboard shortcuts and building a model to simulate human performance. I was looking for software that would time tasks on its own (how I thought this would happen, I don't know!) but once reality hit, I realized that the datalogger was great so I could keep time on my own and compare it to the time on our videotape.” — KN, USA
