A must-have practical tool for personal habit tracking
None of the existing habit tracking apps help me discover the factors that either enable me to or distract me from my goals. Using this easy pocket tool, I can create my own habit tracking "app" and stay productive daily and weekly.
With Family Sharing set up, up to six family members can use this app.
