Distance Traveled Calculator

Distance Traveled Calculator – Planned Feature in TimeTrack Pro

Automatically estimate total distance walked, cycled, driven, or traveled from your timeline — useful for fitness, mileage claims, curiosity, or budgeting — all processed offline on your device.

1. How Distance Will Be Calculated

Using Haversine formula (standard for lat/long points):

  • Connect consecutive timeline points
  • Sum straight-line distances (ignores curves but good approximation)
  • Filter by activity (e.g. only "in vehicle" or "on bicycle")
  • Account for accuracy radius → ignore tiny jumps

2. Planned Interface & Usage

  1. Import timeline files
  2. Go to Stats → Distance Calculator (new section)
  3. Select date range (day/week/month/year)
  4. Choose filter (all movement, walking only, driving only)
  5. App calculates locally → shows total km/miles + breakdown
  6. Copy result or export CSV (date, segment distance, total)

3. Accuracy & Limitations

  • Good for: Daily totals, monthly mileage, fitness tracking
  • Underestimates curves — real road distance ~10–20% higher
  • Better with dense points — frequent logging = more accurate
  • Battery-saving mode — still usable (larger jumps, ~15% error)

4. Practical Use Cases

  • Tax mileage deduction: Annual km for self-employed
  • Fitness goals: Weekly walking/cycling distance
  • Commute cost: Fuel estimate from work trips
  • Travel bragging: "I walked 1,200 km this year"
  • Carbon footprint: Rough personal travel impact

5. Privacy & Battery Benefits

  • No GPS used by app — only processes existing export
  • No data sent — full offline calculation
  • Encryption option for saved stats
  • Instant delete after use

6. Manual Alternative Until Feature Arrives

  • Copy times between distant points
  • Use online map tool (privately) to measure segments
  • Sum manually in spreadsheet
  • Focus on key trips for estimates

Coming soon: Accurate, private distance totals from your own data — no apps, no tracking, no subscriptions.
