水準測量手簿-測量野帳・測量計算・水準計算

A field notebook app specifically designed for leveling surveys, usable on-site!

Automates all calculations previously done in paper field notebooks. Simply input the values ​​to complete calculations for instrument height (HI), ground height, and closure error, as well as pass/fail judgments based on comparison with allowable errors.

Detailed settings are also available.

【Recommended for】
・Those conducting leveling surveys in construction, civil engineering, and surveying sites
・Those struggling with calculation and transcription errors in paper field notebooks
・Those who want to complete everything from recording to inspection on-site using only a smartphone

【Main Features】

"Automatic Calculation using Instrument Height Method (HI Method)"
Simply input BS (Backsight) and FS (Foresight) to automatically calculate instrument height and ground height. Supports a single-line layout for BS/FS.

"Accuracy Management and Inspection Calculation"
Set the allowable error K (standard values ​​for grades 1-4 are automatically entered) for each survey. Automatically determines pass/fail based on comparison with the closure error. Turning on round-trip observation allows you to automatically check the round-trip difference for each section delimited by fixed points.

"Voice Input"
You can input numerical values ​​by reading them aloud while observing staff in the field.

"Customizable Input Order Mode"
You can freely register the order of cells moved after pressing the Enter key or voice input to match your observation style. Skipping unnecessary cells significantly speeds up input.

"Known Point Master"
By registering known points (point name and elevation) for each field, data is automatically entered simply by selecting the survey point name in the field notebook.

"Undo/Redo"
You can undo up to 100 steps, ensuring peace of mind against input errors and accidental deletions.

"Automatic Backup"
Automatically backs up data to your device every time you save (up to 3 generations). Supports export and import in JSON format, making data migration during device changes and accidental recovery easy.

"CSV/HTML Output"
Calculation results can be output in CSV or HTML format. This can be used for printing and creating submission documents.

"Dark Mode & Screen Dimming Prevention"
Supports dark mode for easy viewing at night or in dark environments, and a setting to prevent the screen from dimming while you're typing.

"User Guide"
Includes a user guide with a character demonstrating the actual screen to help even first-time users navigate the app.

[Free Version & Pro Version]
The free version allows you to manage up to two sites for free. Upgrading to the Pro version allows for unlimited management of more sites and surveys.

We prioritize "ease of use" in the field and will continue to make improvements. Please feel free to send us your feedback and requests through the settings within the app.
