Excogni does its best to measure and train cognition while staying honest. It is made in a way where it shows and points to any uncertainty. It is a long way from done, but it is open - open code, open data - to the extent where it can keep users from being singled out. I Hope some of you enjoy it as much as I do. And honestly the app without data is a shell, I hope you will try it out. I am open to all suggestions and will consider them. I'll also make sure to check and respond to any feedback, maybe not at the same moment but I'll do my best to do it today.
