Open STL models on iPhone and iPad, and work with local 3D mesh projects. STL Viewer by Transfer.med.br combines a native viewer with optional Pro and Studio tools.
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.…

For developers and the curious
The evidence, sources, measurements and versions behind every label above.
No review analysis published for this app.
“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.
Supporting measurements: not a complete list of possible harms or positives. Measurement vocabulary 1.4 · how these are measured
Not yet tested. No analysis has been run for this app, so there is no version or date to report.
Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
New Pro workspace for building and editing 3D meshes, multi-object projects, saved revisions and model exports. Includes mesh repair, sampled inspection and PNG capture. Studio adds annotated PDF reports. Safer imports, cancellation and exports that preserve existing files. New tools require a compatible paid plan; basic viewing remains available without a subscription.
Appworthy
stl-viewerWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.
From the store listing. Billing terms are read from each purchase’s name — the stores don’t publish them — so treat them as a strong hint, not a disclosure.
These are really on sale; we just can’t tell from the name whether they recur.
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
