Gewerkton, a construction-site documentation tool, says it replaced the design across its web app, iPhone and Android apps, Studio, 26 icons and 529-page website during a relaunch on Oct. 2-3, 2026. The publisher’s account says AI coding agents handled implementation from written plans, while founder Thorsten Meyer approved the plan, reviewed results and released each part. The development matters as a detailed example of how one software publisher used AI agents in a live product redesign, as described in the original analysis, but the figures and account are self-reported.

The new design, named HORIZON, was applied across the product and website. Gewerkton says the web-app work replaced 281 hard-coded colour values with design tokens, retaining 11 exceptions, and restyled 47 cards. Phone app version 0.5.0 adopted the new look, as did Studio in light and dark modes. All 26 icons were re-rendered in Blender using cobalt and navy. The website spans 40 languages; the company says it uploaded 1,583 files without an error and added 228 AI film runs covering five regions, as well as eight help videos.

The phrase “two days” refers to execution, not a design process that began from scratch on Oct. 2, in a process involving AI coding agents. The source account says an interim draft from Sept. 26 informed the work. Meyer approved a written plan that listed unresolved decisions, options and recommendations. Agents worked on a separate copy of the code and branch, and each section remained unreleased until Meyer reviewed and approved it. Film versions showing the updated interface were held until he had seen the interface on Oct. 3; paid film reruns also required his explicit approval.

Gewerkton reports that its web-app checks covered 200 views in English, German, Japanese and Hindi, at three screen widths and in light and dark modes. It says the phone app passed 853 of 853 tests, Studio passed 2,158 of 2,158, and the website passed seven test suites. The web-app suite still had eight failing tests across seven files: the company says six files failed the same way on the main branch and one failure depended on test order, so it did not attribute those failures to the redesign. It also says the live site was checked after upload.

Human Review in an Agent-Led Relaunch

The account gives a concrete view of the division of work in an AI-assisted software release: agents performed implementation, while a person controlled approvals, release timing and exceptions. Meyer also had to accept Apple’s latest Program License Agreement before the iPhone build could proceed, a step the company says only he could complete. That is a practical limit on agent autonomy, separate from how well the agents handled code.

The reported problems show why automated tests were not the only check. Meyer spotted icon tiles that obscured nearby labels in dark mode, a defect no test had caught. The team also visually checked films after a colour-replacement mask missed red areas in shadow or warm light. These examples do not establish how the process would perform at other companies or at a different scale, but they show that a rapid implementation still depended on human inspection and release gates.

Gewerkton says the original cobalt colour reached a contrast ratio of 4.38:1 against a light background, below the team’s stated 4.5:1 working threshold under WCAG 2.1 AA. It darkened the colour to 4.80:1 rather than shipping the original. The episode illustrates how a planned visual change can require a measured adjustment before release. The source does not provide an independent accessibility audit.

How the Two-Day Schedule Was Defined

The company’s disclosure says Gewerkton is built by the publisher of the source account, ThorstenMeyerAI.com. Meyer develops the product in Iffeldorf, Bavaria, and directs a fleet of AI coding agents identified as Codex and Claude. That relationship is relevant when weighing the report: the published implementation counts, test results and cost figures come from the team responsible for the work, rather than an outside evaluator.

The relaunch’s schedule began with an interim design draft dated Sept. 26. The two-day period on Oct. 2 and 3 covered execution from an approved plan through the live website. The project also included media production, not only software and web design. Of 228 film runs, 222 had a regional version of their own, according to the account. The team visually inspected the middle frame of each of 157 mirrored films and reviewed reworked films again at 10%, 50% and 90% of their duration.

The company says film production paused after round nine when 38% of jobs were failing, with 208 of 228 runs completed at that point. It reports that the 76 failed jobs were not billed. Earlier, 80 industry clips were redone after the first image model made little change to faces. These figures describe the project’s own production records; the available account does not set out an external comparison for the failure rate or overall cost.

What the Project Report Leaves Open

The account is a publisher’s description of its own relaunch. It does not include independent verification of the implementation totals, test results, accessibility measurements or film-production figures. The source material also ends mid-sentence while introducing the film cost, giving only the incomplete wording “about 134 dollars actual”; it does not provide enough information to state what that amount covers or whether it represents total project spending.

Some reported fixes were still pending. Five major findings from an Android test on a Pixel 10a were not blockers, but were scheduled for version 0.5.1. One involved camera-screen buttons breaking words across lines after the redesign increased type size and padding. The account does not give a release date for that version. It says nine regional film runs were later reshot with Meyer’s approval and passed visual review, while 10 regional versions with leftover red were temporarily switched to the European cut. The full status of every regional film after those changes is not specified.

Version 0.5.1 and Film Follow-Up

The next stated product milestone is phone app version 0.5.1, which Gewerkton says is scheduled to address all five major findings from its Pixel 10a Android test. The company has not supplied a release date in the source account, so it is not clear when those changes will reach users or whether further testing will identify other issues.

For the film work, the account says nine runs were reshot and passed visual review after Meyer approved them. It does not give a final completion date for all regional versions or explain when the 10 versions temporarily replaced by the European cut will receive their own updated edits. Further updates to those details, along with a complete description of the reported film cost, would clarify the final scope of the relaunch.

Key Questions

What happened during Gewerkton’s relaunch?

Gewerkton says it applied its HORIZON design to the web app, iPhone and Android apps, Studio, 26 icons and 529-page website on Oct. 2-3, 2026. The account also describes 228 AI film runs across five regions.

Did AI agents make all the release decisions?

No. The publisher says Codex and Claude agents implemented changes from written plans, but Thorsten Meyer approved the plan, reviewed work and released each part. Paid film reruns required his approval, and he had to accept Apple’s license agreement to unblock the iPhone build.

How did Gewerkton test the redesign?

The company reports app and Studio test runs, checks of the website at multiple widths and in five regions, and visual inspections of the interface and films. It also disclosed eight web-app test failures that it says were pre-existing or dependent on test order, rather than caused by the redesign.

What problems did the team find?

A dark-mode icon treatment obscured nearby labels, and automated colour masks missed some red areas in films. A Pixel 10a Android test also found five major issues, including camera-screen buttons wrapping mid-word. The publisher says the Android findings are scheduled for version 0.5.1.

Is the reported cost of the relaunch known?

Not from the supplied account. Its final line begins to give an actual film cost of “about 134 dollars” but is cut off before explaining what the figure covers. It does not establish the total cost of the relaunch.
