Gewerkton, a construction-site documentation tool, says it replaced the look of its web app, iPhone and Android apps, Studio, 26 icons and website in a two-day implementation led by AI coding agents. The work ran on Oct. 2-3, 2026, under plans approved by founder Thorsten Meyer, who checked the results and released each part; the company’s publisher builds Gewerkton, a disclosure relevant to its account of the project.

The redesign, called HORIZON, changed 281 hard-coded web-app colour values to design tokens, leaving 11 stated exceptions, and restyled 47 cards. The phone app moved to the new look in version 0.5.0 for iPhone and Android. Studio received light and dark versions, and all 26 icons were re-rendered in Blender in cobalt and navy.

The website comprises 529 pages in 40 languages. Gewerkton says it added a new opening section featuring real product screens and uploaded 1,583 files without an error. It also reports 228 AI film runs for five regions, including 222 regional versions, and eight help videos. These figures are the company’s account; independent verification is not provided in the source material.

The work followed written plans that listed open decisions, options and recommendations. Meyer approved the recommendations, while agents worked on a separate code branch. According to Gewerkton, no part was merged or delivered until he approved its release. Films showing the new interface were held until he had reviewed it on Oct. 3, and paid reruns also required his explicit approval.

Human Review Shaped the AI Relaunch

The account shows how Gewerkton divided work between automated implementation and human decisions. Agents carried out planned changes, but the founder controlled approvals, releases and paid reruns. Apple’s licensing requirement also imposed a human-only step: the iPhone build could not proceed until Meyer accepted an updated Program License Agreement.

The reported problems illustrate why passing tests did not settle whether the relaunch was ready. The first icon treatment used white tiles that obscured nearby labels in dark mode; Meyer spotted the issue during visual review, though no test flagged it. The company says a script, a separate dark icon variant and a layout correction were then released that evening.

Film recolouring offered another limit. An automated mask missed red in shadows and warm backlighting, while broader attempts sometimes coloured lips or faces blue. Gewerkton says people found these defects during visual checks, leading to 24 files being cleaned and 10 regional versions temporarily switched to a European cut. Nine of the affected runs were later reshot with Meyer’s approval. The examples matter because they show that a fast implementation still required human inspection of visual output.

A Draft Preceded the Two-Day Push

The phrase “two days” describes execution from an approved plan to the live website, not the full design process beginning from a blank slate. Gewerkton says an interim design draft dated Sept. 26 was carried into the Oct. 2-3 work. The distinction matters when interpreting the speed claim: the two-day period covered implementation and release, while some design work had already taken place.

Gewerkton is built in Iffeldorf, Bavaria, by Thorsten Meyer, who says he directs a fleet of coding agents, including Codex and Claude. The publisher’s disclosure says it builds Gewerkton itself and documents what it learns. The source describes this particular relaunch and its internal checks; it does not provide an independent comparison with conventional development or evidence about how the approach performs on other projects.

The company reports that the web app was visually inspected in 200 views across English, German, Japanese and Hindi, at widths of 390, 834 and 1,440 pixels, in light and dark modes. It says the phone app passed 853 of 853 tests and Studio passed 2,158 of 2,158. The website passed seven test suites and was checked across three widths and five regions, both before and after upload.

““Two days” needs one qualification.”

Test Failures and Fixes Remain

Gewerkton says eight web-app tests failed across seven files. Six files reportedly fail the same way on the main branch, and one failure depends on test order and passes when run alone. The company says the redesign did not cause these failures, but also did not fix them. The supplied account does not include independent test records or enough detail to assess the underlying failures.

The company also describes five major findings in an Android test on a Pixel 10a, including camera-screen buttons that break words across lines after the new type and padding were introduced. It says none was a blocker and that all five are scheduled for version 0.5.1. The source does not say whether that update has shipped.

Film production paused after round nine when 38 percent of jobs were failing, with 208 of the 228 runs completed at that point. Gewerkton says the 76 failed jobs were not billed, but the supplied cost information is incomplete: it ends after stating that project records show about $134 in actual costs for the films. No full project cost, labour figure or broader cost comparison is available in the material.

Version 0.5.1 Is the Next Fix

Gewerkton says the five Android findings are scheduled for version 0.5.1. The account does not give a release date, so it is not clear when users will receive the button and other reported fixes.

The company says nine film runs were reshot after visual review and approved by Meyer. It has not provided a later status for the remaining regional versions that were temporarily switched to the European cut, or said whether any additional film corrections are planned. The supplied material also does not state whether the unresolved web-app test failures will be addressed separately.

For now, the relaunch is presented as a completed release with follow-up work still pending. Gewerkton’s next reported milestone is the Android update; further information about the remaining fixes, final film versions and total costs would clarify what the two-day rollout left outstanding.

Key Questions

What did Gewerkton relaunch?

Gewerkton says the HORIZON redesign covered its web app, iPhone and Android apps, Studio, 26 icons and a 529-page website in 40 languages.

Did the entire design process take two days?

No. The company says an interim design draft dated Sept. 26, 2026, preceded the Oct. 2-3 implementation. Its two-day description refers to execution from an approved plan through the live website.

What role did AI agents play?

Gewerkton says agents including Codex and Claude implemented work from written plans on a separate code branch. Founder Thorsten Meyer approved plans and releases, reviewed visual results and authorized paid film reruns.

Were there problems during the relaunch?

Yes. The company reports an icon treatment that obscured labels in dark mode, film recolouring defects, an Android button-wrapping issue and eight web-app test failures. It says the Android findings are scheduled for version 0.5.1; the source does not say when that release will ship.

How much did the film work cost?

The available project account gives about $134 in actual film costs, but the source text ends before providing further detail. It does not give a complete project cost or labour figure.
