Gewerkton, a construction-site documentation tool, replaced the look of its web app, iPhone and Android apps, Studio, icons and multilingual website on Oct. 2-3, 2026, using AI coding agents to implement an approved redesign, as detailed in the original analysis. Publisher and developer Thorsten Meyer says he approved the plans, reviewed results and released each part; the project also exposed defects that automated checks did not catch.

The new design is called HORIZON. Gewerkton says the web app’s 281 hard-coded colour values were moved to design tokens, with 11 exceptions retained, and 47 cards were restyled. The phone app was updated as version 0.5.0, while the Studio received light and dark versions of the design. All 26 icons were rendered again in Blender using cobalt and navy.

The website comprises 529 pages in 40 languages. The publisher says it uploaded 1,583 files without errors and added a new opening section featuring real product screens. The rollout also included 228 AI film runs for five regions, of which 222 had a region-specific version, along with eight help videos. The publisher describes the execution as taking two days, but says an interim design draft from Sept. 26 informed the work.

Gewerkton reports that implementation began from a written plan listing open decisions, options and recommendations. Meyer approved the plan as recommended. The agents worked on a separate code branch, and no part was merged or delivered before his release. Films showing the apps were held until he had reviewed the new interface on Oct. 3; paid film reruns also required his approval. Apple’s developer agreement presented a separate human-only step: the iPhone build could not proceed until Meyer accepted the latest Program License Agreement.

Human Review Shaped the AI Rollout

The account offers a specific example of AI agents handling a substantial product implementation while a human retained approval and release authority. The agents carried out work across several platforms and hundreds of web pages, but the workflow did not treat their output as ready to ship automatically. Design decisions, paid reruns, app demonstrations and final releases had human gates.

The reported problems show why that distinction matters. Meyer says the initial icons appeared on white tiles that obscured nearby labels in dark mode, an issue found during visual inspection rather than testing. The film recolouring process also missed red details in shadows and warm lighting. Those findings led to corrections, replacement regional cuts and additional review. For readers evaluating AI-assisted software work, the project illustrates both the scale such agents can help deliver and the limits of relying on automated checks alone.

The figures and results here come from the publisher’s own account, not an independent audit. They describe this project and do not establish how the same workflow would perform elsewhere.

A Two-Day Release With a Head Start

Gewerkton is built in Iffeldorf, Bavaria, by Thorsten Meyer, who says he directs a fleet of AI coding agents using Codex and Claude. The publisher disclosed that Gewerkton is built by the publisher itself and that it is documenting what it learns. That relationship is relevant when weighing the project’s performance claims: the account is a first-party description rather than an outside assessment.

The stated two-day period refers to execution from an approved plan to the live website, not to the full design process. An interim draft dated Sept. 26 was carried into the Oct. 2-3 work. The publisher says agents followed written instructions in a separate copy of the code, while Meyer reviewed output and decided when each component could be released.

Gewerkton says its working accessibility standard for colour contrast follows WCAG 2.1 AA. During the redesign, the planned cobalt colour measured 4.38:1 against a light background, below the project’s 4.5:1 working threshold. The team darkened it to 4.80:1 rather than ship the original shade.

“The agents worked in a separate copy of the code on their own branch.”

Independent Verification Is Not Provided

The project figures, test totals and reported film costs are publisher-reported; the supplied account does not include an independent audit, external test results or a separate confirmation from Apple. It also does not provide a full accounting of the labour involved in planning, reviewing and correcting the work, so the figures do not establish the overall cost or efficiency of the approach.

The web app had eight failing tests across seven files. Gewerkton says six files fail in the same way on the main branch and one test depends on run order and passes when run alone, meaning the redesign did not cause those failures. The account does not specify what the remaining failure means or provide enough detail to independently examine the test suite. The company says those failures were not fixed as part of the redesign.

For the films, the account says production paused after round nine when 38% of jobs were failing, with 208 of 228 runs completed at that point; the 76 failed jobs were not billed. It reports about $134 in actual film costs, but does not give a detailed cost breakdown. The account also does not explain whether the remaining issues or planned regional replacements have since been completed.

Version 0.5.1 Holds App Fixes

Gewerkton says five major findings from an Android test on a Pixel 10a are scheduled for version 0.5.1, with none classified as a blocker. One described defect affects camera-screen buttons: larger text and added padding caused words to break mid-word, and the German cancel label wraps onto two lines. The account does not give a release date for the update.

The film work also involved follow-up beyond the initial runs. After visual review, 24 files were cleaned and 10 regional versions with leftover red were temporarily replaced with the European cut. Gewerkton says nine of those runs were later reshot with Meyer’s approval and passed visual checks. The supplied account does not state whether the remaining version has since been revised.

The next reported milestone is therefore the app update and any outstanding film corrections, rather than a further announced redesign. The publisher has not provided a schedule for those remaining items or independent results from a post-release review.

Key Questions

What changed in Gewerkton’s redesign?

The HORIZON look was applied to the web app, iPhone and Android apps, Studio, 26 icons and a 529-page website available in 40 languages. The rollout also included AI-generated film runs and help videos.

Did AI agents make the design and release decisions?

According to Gewerkton, the agents implemented a written, approved plan. Thorsten Meyer approved that plan, reviewed results and released each part. The account says paid film reruns and films showing the apps also required his approval.

What problems were found during the rollout?

Visual review caught icons on white tiles that obscured labels in dark mode and red details missed by the film recolouring process. An Android test also found camera-screen buttons breaking across words. Gewerkton says five major Android findings are planned for version 0.5.1.

How much did the film runs cost?

The publisher’s account gives about $134 in actual film costs and says 76 failed jobs were not billed. It does not provide a full project cost breakdown, including planning and review time.

Were the reported results independently verified?

No independent audit or external confirmation is included in the supplied account. The test totals, implementation details and rollout results are reported by Gewerkton’s publisher, which disclosed that it builds the product.
