Do you want to be a better person? Maybe you want to curse less, drink more water, or post fewer inflammatory comments on the internet. You could go the old school route by wearing a rubber band around your wrist and snapping it every time you slip, or literally pat yourself on the back when you do the right thing.

After an unpleasant conference call, [Darian] cursed a blue streak that left his coworkers shocked and speechless. This inciting incident began the hero’s journey that will end with a kinder, gentler [Darian], as long as he has his trusty Be Better Bracelet. He tried involving Alexa when at home, and various apps elsewhere to track these venomous utterances, but he yearned for a single solution that’s always available.
The sole purpose of this bracelet is low-cost, unobtrusive habit tracking. Though tied to a phone, it won’t tell time, predict the weather, or alert the user to incoming what-have-yous. It will simply record button presses, which are assigned meaning in the app settings. It’s up to the user to set goals, analyze the data, and reward or punish themselves accordingly.
[Darian] is still working out the design kinks to make this as small and cheap as possible. If you have suggestions, let him know.
