The 4PS On-Site App was specially designed for use on construction sites of non-residential as well as residential building projects. The 4PS On-Site App can be used for recording and processing issues for projects, for uploading and sharing documents and pictures of a project and filling in standardized checklists which are sent to the back-office.

Verdict
The clearest difference is update cadence: E at every 2 weeks against 4PS On's every 2 months. E also leads on iOS requirement (12.4 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
