Selfstock turns your steps, sleep and focus from Apple Health into one personal index that starts at 100 and moves every day. Better than your usual day, it goes up. Worse, it goes down.
See every day on an up/down calendar, get a recap every Monday, halt trading on sick days, and compare returns with friends in private groups. Everyone is measured only against their own baseline.
All health data is calculated on your iPhone. No account, no ads, no tracking.
