How to use IsoMap

  1. Pick a destination, the place you travel to most. Press + Add to combine it with a second one, or ◎ Pin to use any spot.
  2. Choose modes and when. Public transport, bike, Lime or a mix. Weekday or weekend, the time, there or home.
  3. Read the colours.
    • Bands: minutes to the destination. Dark is quick.
    • Within max: clear is within your Max. Grey is not.
    • Fit: dark is closest to all your asks at once.
    • Rent: typical asking rent. Dark is cheap.
  4. Filter. Living costs greys out places over your buy or rent limit. Near shows stations, pools, parks and more, with an optional walk limit.
  5. Click any spot for its times across the week and what is around it.
  6. Save to shortlist to compare places. Copy link shares exactly this view.

The risk asks (avoid noise, air pollution, flood or crime) are rows in the Fit view. They are off until you give them a weight.

What needs the home engine

The step-by-step route in the details panel, and bike times to a pinned destination, need the home engine: a laptop that is usually off. Everything else is precomputed and always works.
