Common Questions
How do I create a project?
Tap the new project icon on the home screen, enter a project title, then use the plus button to choose a module and calculation item.
Why is there no result?
A calculation runs automatically only after every required numeric input is complete. Check blank values, unit selections and physically invalid values.
Are negative values supported?
Yes. Numeric inputs support negative values and scientific notation for cases such as negative elevation, vacuum gauge pressure or small diffusivity.
Is data uploaded?
No. Projects, favorites, recents and settings stay on device. Backup files are managed by the user locally.
Basic Workflow
- Start from an engineering project on the home screen, or open a calculation module for a single calculation.
- After a work item is added to a project, all input values start blank.
- When all required numeric values are entered, results calculate automatically and stay in the local project.
- Use Settings to change precision, language, appearance or default unit system.
Backup and Restore
Backup and restore are available in Settings. During restore, new data is added to the device. If a matching project exists, the app asks whether to overwrite matches or add new data only.
Result Verification
Each calculation module includes formula and scope information. Before real project use, verify results against project standards, vendor data, site conditions and professional judgment.
