STEP File Viewer downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
73/100
faster than 89% of Developer Tools apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About STEP File Viewer
STEP File Viewer is a lightweight yet powerful tool for viewing .step and .stp files on macOS, iPad, and iPhone.
Key Features
• View STEP models in 3D with rotate, pan, and zoom controls using perspective projection.
• Display 3D models in solid, shaded, or wireframe modes.
• Load and view IGES/IGS models.
• Supports assembly-level colors and exploded views (requires the model to include assembly data).
• Parse and load STEP models as assemblies
• Support PMI annotations, dimension details, and model information panels in AP242 models for easier design review.
• Measure auto-detected hole features, bounding box dimensions, point-to-point distances, diameter/radius, and angles to verify key dimensions more quickly.
• Pin review notes on the model to record issues, jump back to each note’s viewpoint, and export a review report as PDF with screenshots.
• Apply axis-aligned section planes (XY, XZ, YZ) to reveal the model’s internal geometry.
• Explode model components to inspect the parts clearly in expanded space, with the ability to export selected parts as separate files.
• Export 3D models in STL, OBJ, glTF, GLB, or USDZ formats for further use or sharing.
• Capture high-quality viewport screenshots for easy sharing.
• No ads. No tracking. No data collection. Just a clean, efficient tool built for productivity.
