and minutes. Think of it as a duration tape — you key in a time, press +
or −, and the running total updates instantly.

PRIVACY
All your calculations stay on your iPhone. ChronoSum has no account, no
login, no backend, and no analytics. The only network traffic is the
in-app banner ad served by Google AdMob.
