Sketchalyze vs ONELAB
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Sketchalyze
This app allows users to sketch and analyze structural systems directly on their iPad. It provides instant visualization of analysis results like deformations and section forces, performing finite element analysis in the background. Users can define cross-sections, apply loads, and visualize results for linear and nonlinear analyses.
- Sketch structural systems
- Instant analysis results visualization
- Finite element analysis
- Tabulated and user-defined cross sections
- Truss and beam element types
- Linear and nonlinear analysis

ONELAB (http://onelab.info) is a finite element package based on the open source mesh generator Gmsh (http://gmsh.info) and the solver GetDP (http://getdp.info). It can be used to simulate a wide variety of multi-physic problems: electromagnetics, thermics, mechanics... ONELAB comes packaged with a selection of ready-to-use examples. New models can be added simply by opening the corresponding zip archive (in Safari, iCloud, Dropbox, etc.).

Verdict
Sketchalyze and ONELAB both sit at 5.0 stars, but that hides the real split: 100% of ONELAB's written reviews are positive against 60% of Sketchalyze's. ONELAB also leads on update cadence (every 2 months vs every 13 months) and iOS requirement (9.0 vs 15.6). Sketchalyze's advantage is ratings volume (7 vs 1). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 5.0 for Sketchalyze against 5.0 for ONELAB. That said, the two scores are not equally well evidenced: Sketchalyze has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 60% of Sketchalyze's written reviews are positive against 100% of ONELAB's.
Sketchalyze ships an update every 13 months, ONELAB every 2 months. The most recent releases landed on October 1, 2026 and October 10, 2026 respectively.
