Built for the moment lightning cracks

Every screen is tuned for one-handed use in the dark, mid-storm — big numbers, honest colours, no clutter.

Live session

The distance ring you read at a glance

Hit Flash, hit Thunder, and the ring fills with the live gap. Mega Joker converts the delay into distance and tells you if the cell is receding or closing — right down to the last strike 58 seconds ago.

  • Closest strike and storm speed, front and centre
  • Trend arrow — approaching or pulling away
  • Every tap dropped straight into the strike log
Live session with distance ring, flash and thunder buttons, closest strike and storm speed tiles
