Meet Cadence, an adaptive day planner. Most apps assume your energy is the same every day, but it never is. Every morning, Cadence reads your sleep and HRV from Apple Health to understand how you actually feel (or just asks you directly if you'd rather not connect it). You add your tasks, and Cadence plans your day around your real energy. Slept badly? It suggests a Light day. Feeling sharp? It builds a Focus day.
