Common Questions
Does the app require an account?
No. Plumbline Studio is designed for local iPhone use with no sign-in of any kind.
Where is my data stored?
All project and measurement data is stored on your device in a local SwiftData database. Nothing is synced to a server.
How do I export my measurements?
Open any project in the Journal tab, then tap "Export PDF" for a formatted report or "Export CSV" for a spreadsheet-compatible file. Both use the iOS share sheet so you can save to Files, email, or any other app.
What is the Triangle Solver?
It solves any triangle given enough known information. Choose a mode (Right, SSS, SAS, ASA, or AAS), fill in the known values, and all remaining sides, angles, and area are calculated instantly. Find it in the Pro tab or the Toolbox screen.
What is the Board-Foot Calculator?
A lumber volume and cost estimator. Add boards (thickness × width × length), pick a species from the 28-species price reference, and it gives you board feet, cost per piece, and a grand total with a waste factor you can adjust. Find it in the Pro tab or the Toolbox screen.
How do I remove the app?
Delete the app from your device. Any data stored only inside the app is removed by iOS when the app is deleted.
