This is an app which is meant to assist people trying to end unhealthy addictions- be it drugs, cutting, alcohol, gambling...
It features a timer which keeps track of the time you've spent sober. You can write notes to keep track of all the reasons you want to quit- and motivational packs for
additional encouragement. There's a community section in which you can find groups and
communicate through posts, to assure you that you aren't always alone in your suffering.
