I'm looking for something online or an app, really anything that is on an electronic device, that can help with cheshbon hanefesh.
The ideal would be a program or app specifically set up for cheshbon hanefesh, but anything will do.
how about this http://dafyomireview.com/db see the tab "cheshbon hanefesh tracker" on the left menu.
Specify Daily Resolutions to Track. Can filter by day of the week.
Track by either integer, float, time, yes/no, or user-defined values
Daily Check In.
Optional Fine System for Enforcement
Graph of Results/Export Data
Daily Email of Resolutions
it's basically a general purpose data plotter adapted for tracking resolutions.
