Throughline makes value stream mapping simple. Built for teams practising Lean and continuous improvement, it puts a powerful process mapping tool in your pocket.

No sign-up. No cloud. Just open the app and start mapping.

▸ MAP YOUR PROCESS
Add steps with active work time, wait time, and quality metrics. Throughline calculates lead time, process efficiency, and identifies bottlenecks automatically.

▸ SEE WASTE CLEARLY
The proportional timeline export shows process time vs wait time at a glance — making waste impossible to ignore. This is the "ah-ha moment" that drives improvement.

▸ BRANCHING FLOWS
Real processes aren't always linear. Switch to branching mode for flows with parallel paths, rework loops, and multiple routes. Critical path analysis highlights the longest path through your map.

▸ CURRENT vs FUTURE STATE
Plan improvements with future state mapping. The built-in diff view compares current and future side-by-side, showing exactly where you'll gain time and quality.

▸ BUILT FOR THE GEMBA
Throughline is designed for where work happens — on the factory floor, in the office, at the whiteboard. The mobile-first interface makes it fast to capture what you see.

• Tap-to-edit cards with plain-language explanations
• Drag to reorder steps
• Identify constraints at a glance
• Queue size and batch size tracking

▸ SHARE YOUR MAPS
Export as PNG, PDF, YAML, or CSV. The landscape timeline export creates a clean, proportional visualisation perfect for presentations and A3 reports.

▸ PRIVACY FIRST
Your VSM data stays on your device — no account, no cloud sync. The app uses anonymous analytics to understand which features are useful. No personal data, and no content from your maps, ever leaves your device.
