Construction Defect Tracker
Read full descriptionHide full description
This app has been created for tracking defects like e.g. construction defects or maintenance tasks. The server software is available as open source at https://git.elbe5cloud.de/CodefApp. The app can be connected to a dedicated server. Yet this is only needed if you want to store your data at a central location. You can get support for creating and running a dedicated server at www.elbe5.de. The structure of this app includes projects, units and defects. Additionally it includes a pool of companies for assigning them to one or more projects and there to their defects for further processing. Projects can be e.g. construction tasks or buildings. From the pool of all companies the relevant ones are assigned to each project. Units are parts of the project like a floor or a room. Units can have a (ground )plan, where defects can be marked on. Defects include a name or short description, a description of the defect, a status, an assignment to a company, a target date, a position on the ground plan and images and/or photos. Defects are processed using status changes with comment, new status, new assignment and new images or photos. For units and defects PDF reports can be created and stored or mailed. All data can be backed up and restored later. If you use a server, all items can be synchronized to and from the server. And one more thing: This a quite large app and no software is free of errors. If you find any errors, please tell me! I will be happy to fix them.

Verdict
The clearest difference is update cadence: Construction Defect Tracker at every 3 weeks against i's every 5 months. i's advantage is iOS requirement (14.0 vs 16.6). On price, ads, in-app purchases and device support there is nothing between them.
