JamWatch

Causeway jam right now? JamWatch tells you exactly how long the crossing takes at Woodlands Checkpoint and Tuas Second Link — live, in both directions, before you leave the house. Two crossings. One glance. No guessing. WHAT JAMWATCH ANSWERS "How bad is the Causeway jam now?" Live travel time for Woodlands Causeway, refreshed continuously while the app is open. "Woodlands or Tuas — which one is faster?" JamWatch names the faster crossing and tells you exactly how many minutes you save by taking it. "Can I check without picking up my phone?" Yes. JamWatch runs on Apple CarPlay and on Apple Watch. On the car screen both crossings and both directions are listed at once, fastest first. On your wrist, one swipe changes direction, and a complication keeps the wait on your watch face. "When should I leave?" Every crossing shows 12 hours of real traffic history against a typical-day average, then projects 6 hours ahead so you can see the next clear window instead of guessing. "What does it actually look like right now?" Live camera stills from both checkpoints — approaching, entering and exiting — sourced from Singapore and Malaysia traffic cameras. "Will the weather make it worse?" Rain and thunderstorms automatically add buffer time to your estimate, so the number you see is the number you should plan for. FEATURES Live travel times Real-time estimates for Woodlands Causeway and Tuas Second Link, both directions, SG to MY and MY to SG. Home Screen and Lock Screen widgets Small (2x2) and Medium (4x2) WidgetKit widgets show the current wait without opening the app. Glance at your Lock Screen and decide whether to go now or wait.
