What is HammerTime?
HammerTime is a free curling delivery timer built by a curler, for curlers. Time your rocks from Back Line to Hog, T-Line to Hog, or Hog to Hog — and log where each one ends up.
How to Use
1. Select a timing category — choose Back Line to Hog Line, T-Line to Hog Line, or Hog Line to Hog Line at the top.
2. Start & Stop — tap the large Start button when the rock is released, tap Stop when it crosses the hog line. The time is saved automatically.
3. Log the result — use the dropdown on each entry to record where the rock ended up.
4. Reset — tap the reset button to clear the current time without saving.
Each category stores up to 16 times — a full end. Times persist between sessions. Use the ✕ button to remove individual entries, or Clear to wipe the full list.
Display Modes
