The easy and fastest way to analyze the 2D-Truss problem right on your iPhone & iPod Touch. Featuring: • Standard Truss Templates: with the standard truss template (18 types of truss for initial version) , you can easily create and config your truss as required. • "Custom Truss"; If the built-in standard truss template doesn't match your requirement, "Custom" your own Truss is also easy to create due to the Node & Element generating features. • Unit Flexibility: very flexible in Units system, you can choose any units at your convenience without the requirement to restart the application and the unit system is saved per your truss's project. For example you use m. as node coordinations while you choose mm. for the deflection of the nodes or you can even choose in. or ft. for nodes's deflection (if you really need). • Buit-in material sections library where you can adjust any material's properties with no effect to other truss project. The options to create your own material library will be available for the next update. • PDF Reporting: All result information of your truss are shown in PDF and also you can email this result.

Verdict
The clearest difference is price: Epson iProjection at Free against A's $4.99. Epson iProjection also leads on rating (4.3 vs 2.3) and ratings volume (3.4K vs 3). A's advantage is update cadence (every 5 weeks vs every 6 months). On review sentiment, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Epson iProjection is free to download; A costs $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Epson iProjection holds the better App Store score, 4.3 against 2.3. That said, the two scores are not equally well evidenced: Epson iProjection has 3.4K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 26% of A's written reviews are positive against 20% of Epson iProjection's, so the app with the better star average is not the one people write more warmly about.
A ships an update every 5 weeks, Epson iProjection every 6 months. The most recent releases landed on October 14, 2026 and October 18, 2026 respectively.
