Altitude Graph Explained

Altitude Graph Explained – Planned Feature in TimeTrack Pro

If your phone records altitude (barometer or GPS), TimeTrack Pro will plot elevation changes over time — perfect for hikes, cycling, flights, or elevation-aware analysis — all offline.

1. How Altitude Data Is Captured

  • Barometer sensor: Most modern phones (Pixel, Samsung, OnePlus) — very accurate (±1–3 m)
  • GPS altitude: Less accurate (±10–30 m), used as fallback
  • Exported in JSON: altitude field per point (meters above sea level)
  • Not always present: Older phones or battery-saving mode may omit it

2. Planned Altitude Graph View

  1. Import timeline with altitude data
  2. Go to Stats → Altitude Graph (new tab)
  3. Select date or range
  4. App plots elevation vs time → line graph
  5. Tap points → see exact altitude, time, location
  6. Copy key values or screenshot graph

3. What You Can Learn

  • Total elevation gain/loss — e.g. 850 m climbed on hike
  • Steep sections — sharp rises = hills/climbs
  • High/low points — summit altitude, valley floors
  • Daily elevation trends — stairs at work, hilly commute
  • Flight profiles — takeoff, cruising, landing (if GPS altitude present)

4. Use Cases & Examples

  • Hiking: Compare difficulty of trails
  • Cycling: Identify hilly routes to train or avoid
  • Fitness: Track stair climbing or hill work
  • Travel: See mountain passes or coastal elevation
  • Health: Monitor daily up/down movement

5. Privacy & Compatibility Notes

  • 100% offline graph generation — no map APIs
  • Encryption option for saved graphs
  • Works best on phones with barometer (most flagships 2020+)
  • Battery-saving mode may skip altitude — use high-accuracy for best data

6. Manual Alternative Until Launch

  • Copy altitude values from timeline entries
  • Paste into spreadsheet → plot line chart manually
  • Focus on known elevation changes (hikes, hills)
