Measure What Matters: Precise Time Tracking for Process Improvement
Capture cycle times, takt times, and process durations with a professional digital stopwatch designed for Lean practitioners. Replace manual time studies with tap-to-record simplicity and automatic statistical analysis -- all on your phone or tablet, even offline.
Benefits
Instant Cycle Time Analysis
Record multiple cycles with a single tap and instantly see min, max, average, and standard deviation. No more manual spreadsheet entry -- your data is analyzed the moment you capture it.
Works Offline on the Shop Floor
Leanshift works without internet, so you can record times in the warehouse, on the production line, or anywhere WiFi does not reach. Data syncs automatically when you reconnect.
Structured Time Study Templates
Pre-built templates for common time study formats ensure consistent data collection across your team. Everyone measures the same way, making results comparable and reliable.
Historical Data and Trend Tracking
Every measurement is saved with timestamps and context. Track how cycle times improve over weeks and months, and use the data to set evidence-based improvement targets.
How It Works
Select or Create a Process
Choose an existing process from your list or create a new one. Define the process steps you want to measure and any relevant context (machine, product, shift).
Start Measuring
Tap the start button and record each cycle. The stopwatch captures split times, lap times, and total duration with millisecond precision.
Review Automatic Analysis
After your measurement session, Leanshift calculates key statistics automatically: average cycle time, takt time comparison, variability, and outlier detection.
Save and Compare
All sessions are stored locally and can be compared over time. See how your process performs against previous measurements and your defined target state.
Use Cases
- -Time studies for cycle time optimization on production lines
- -Changeover time measurement for SMED workshops
- -Service process timing for customer wait time reduction
- -Takt time verification during production ramp-ups
- -Before/after comparison for Kaizen event validation
Frequently Asked Questions
Does the stopwatch work without an internet connection?
Yes. Leanshift is a Progressive Web App (PWA) that works fully offline. All data is stored locally on your device and syncs when you reconnect. You can run complete time studies in areas with no WiFi or cellular coverage.
Can I export my time study data?
With the Pro tier, you can export all measurement data as CSV or JSON files for further analysis in spreadsheet software or statistical tools.
How accurate is the digital stopwatch?
The stopwatch uses your device's high-resolution timer and achieves millisecond precision. For typical industrial time studies where human reaction time is the limiting factor, this is more than sufficient.
