Recent reviews

at some point all of my activities were completed but it just never gave me any results of any kind currently trying to Uninstall and reinstall just to see. otherwise. super nifty little tool for self reflection I guess. sort of makes you think and consider things or aspects of one's self you wouldn't normal consider. personally it made me realize something at little as eating chocolate before a meditation can drastically affect said meditation and that's pretty dang interesting¯\_(ツ)_/¯

Download the app and it just does nothing. Sad 😢 because I was really wanting to do this . For being a part of a study that could help us. My mother had dementia,
