Frequently asked questions
Why is the reading different from my physical spirit level?
A phone case, camera bump, contact edge and sensor conditions can affect the result. Check again with steady, even contact on the same surface. Use your physical measuring instrument for critical work.
How do I reset a reference?
Use the reference control to clear the active reference. Save it again after placing the phone in your new position. See the user guide for details.
Is the app free?
It is free to download from the App Store. The app displays banner advertisements. Store availability can vary by region.
What happens if I deny tracking permission?
Manage iOS tracking permission under Settings > Privacy & Security > Tracking. Denying tracking does not turn off all processing by advertising and analytics services. The privacy page explains the services and information involved.
Do I need a support account?
No. You can contact the developer by email. The app has no user account or account-deletion flow.
