A way to motivate people (including myself) to exercise with a chat bot that tracks your progress.
Originally built it to track how often I worked out, and if I didn't, what the reason was and have that reported back to me regularly. Now I have a bunch of people using it, but as you can imagine, makes me zero dollars. Well, technically it costs me money so it makes me negative dollars.
