## What is STL Viewer?

Open your STL file on iPhone or iPad and examine the model with rotation, zoom and technical views. Your app purchase includes basic viewing without a subscription. Pro and Studio are optional upgrades for creation, editing, inspection and reports.

BASIC VIEWER
Open binary or ASCII STL files. Orbit, pan and zoom, switch camera views, and inspect basic model information in solid or wireframe mode.

PRO WORKSPACE
Build with primitives and profiles; extrude and revolve shapes. Transform objects, preview Boolean operations and plane cuts, and use mesh repair tools. Organize multiple objects in local projects with undo, redo and saved revisions. Measure distances, angles and radii, and inspect sampled estimates of wall thickness and surface deviation. Export STL, OBJ, PLY, 3MF and GLB files, capture PNG images, and opt into project reminders.

STUDIO REPORTS
Studio includes Pro and adds local PDF reports with project information, geometry summaries and inspection annotations.

IMPORTANT LIMITS
Models are processed on your device, not uploaded to our servers. Projects and revisions are local. This app does not include cloud collaboration, SSO, STEP/B-rep CAD or manufacturing certification. Thickness and surface comparisons are sampled estimates, not certified measurements. File formats and mesh operations have safety limits and restrictions shown in the tools. STL does not record units; choose the correct unit for your model.

OPTIONAL PLANS
The app download is paid. Basic viewing needs no subscription. Creation, editing and advanced inspection require Pro or Studio; PDF reports require Studio. Monthly/annual subscriptions and Pro Lifetime are optional. The App Store displays prices and periods before purchase. Subscriptions renew automatically until cancelled in your Apple account settings. Restore Purchases is available in the app.
