Survey Stakeout & Slope Calculator helps with batter-board and slope stakeout calculations for surveying and civil construction. The app interface is in Japanese.

Enter known elevation, backsight or instrument-height addition, prism height, design elevation, slope ratio, and a signed observation value. Calculate instrument elevation, observed-point elevation, elevation difference, and the horizontal distance toward or away from the instrument.

FEATURES
- A numbered section diagram and six matching input fields
- Select a planned slope rising or falling away from the instrument
- Basic example and a 1:0.6 cut-slope example
- Bundled reference illustration with zoom and upper/lower instrument positions
- Copy results as text
- Save up to 20 calculation records on the device
- Tap a saved record to restore all six inputs and slope direction, then recalculate
- iPhone, iPad, Dark Mode, larger text, and VoiceOver support

Use a positive slope ratio: enter 0.6 for vertical 1 : horizontal 0.6. For level observations, enter prism height 0 and the staff reading as a negative value. Each calculation stage is rounded to three decimal places, matching the original app.

Calculations and history remain on the device. No account, advertisements, location access, or tracking.

This is a supplementary construction-calculation tool. Check design documents, site conditions, instrument settings, and calculations independently before use.
