FREE FOREVER
Timer for every session type, logging, streaks, 14 days of history, two starter protocols, Apple Health workouts and the shareable streak card.
KOLDA PRO
Unlimited history and full calendar, all protocols and the custom builder, 30-day programs, full stats and trends, photo notes and CSV export.
Pro is available as a weekly or yearly subscription, or a one-time lifetime purchase. The yearly plan starts with a 3-day free trial. Subscriptions renew automatically unless cancelled at least 24 hours before the period ends; payment is charged to your Apple Account and can be managed in Settings.
A quiet note on safety: Kolda is a tracker, not medical advice. Cold exposure has contraindications — if you have a heart condition or are unsure, talk to your doctor first.
