## What is LevelNote?

LevelNote is a digital field book for leveling on construction sites.
With paper-like workflows, you can measure elevations, set out (marking), and manage records quickly.

[Key Features]

■ Measurement Mode (Standard)
Enter a benchmark (BM) and readings (BS / FS) to calculate instrument height (IH) and elevation (EL) automatically.
• Benchmark setup: enter BM and BS
• Point measurement: enter FS to calculate EL
• Multiple benchmarks during a survey
• Select from BM list (Pro): add a saved benchmark
• Custom columns: memo and EL offset columns; adjusted EL is shown automatically
• Delete points from the toolbar (the first benchmark cannot be deleted)
• Custom numeric keypad and auto-focus to the next field
• Floating calculator for basic arithmetic

■ Marking / Set-out Mode (Pro)
Enter a target elevation (EL) to calculate the required reading (FS) automatically.
• Enter target EL; IH and required FS are calculated
• EL offset column: shows adjusted EL and updates required FS
  * Only one EL offset column can be added in Marking
• Memo columns for per-point notes
• Multiple benchmarks and BM list selection
• Delete focused points from the toolbar
• Same custom keypad and calculator as Measurement

■ Benchmark (BM) Management (Pro)
Save benchmarks you reuse and call them up in Measurement or Marking.
• Create / edit name, elevation (EL), photo, and notes
• List view and pick-from-list when adding a benchmark
• Share benchmarks as files with your team
  * Recipients need Pro / LevelNote v1.6.0 or later
• Import from the Benchmarks screen, or open a shared file in LevelNote

■ Survey Records
Save Measurement and Marking data and review it anytime.
• Save records (name when leaving; blank names use a date default)
• List: name, date, point count, and mode
• Detail table including custom columns; resume to continue editing
• Swipe to delete; Select for bulk CSV share or delete
• CSV export from detail or bulk selection (includes memo / EL offset headers)
  Share to Files, Mail, and more—useful for Excel and submissions

[About Pro]
