Heat Timer

Follow the heat

Start the clock, then tap to mark runs, transitions, and work stations. The course alternates one-kilometre runs with ski erg, sled push, sled pull, burpee broad jump, row, farmers carry, sandbag lunges, and wall balls. The large clock and station ring make the current segment easy to see.

Choose the extras you use

The race clock and most recent heat are free. Separate one-time purchases add Heat History with saved splits and share cards, Station Practice for individual work stations, or Doubles with partner assignments and a rest timer on the same iPhone. Buying one add-on does not unlock the others.

Made for the training floor

Heat Timer can keep the screen awake while a heat is running. It has no account, training-data server, or Apple Watch app. It is not affiliated with any race organizer.

Purchases through Apple

Available options and current localized prices appear in the app before purchase. Apple processes payments. The optional add-ons are one-time purchases, with no recurring subscription.
