I've used the Bitalino with several classes during the last few months. Overall, it worked great. However, one missing feature has cost us some (indeed, quite a lot) data: After the measurement, it's quite easy to (accidentally) close the Open Signals software, and all data is lost. It would be great if an autosave feature (maybe with a checkbox that is remembered over session) could be implemented, so before the app exits, the data is saved in any case (maybe with a timestamp as filename). For myself, I've gotten aware of the problem, but with students, every student team had to learn it the hard way (of course I told them, but ...).
Thanks for your great device & software!
