Gewerkton, a construction-site documentation tool, says it replaced the design across its web and phone apps, Studio, icons and multilingual website on Oct. 2 and 3, 2026, using AI coding agents to implement an approved plan, as detailed in the original analysis. The company says its founder, Thorsten Meyer, reviewed the work and controlled releases; the account is published by the same publisher that built Gewerkton, and the results have not been independently verified.

The relaunch introduced the HORIZON design across Gewerkton’s web app, iPhone and Android apps, Studio and 26 icons. The website was updated across 529 pages in 40 languages. Gewerkton also reports uploading 1,583 files without an error and producing 228 AI film runs for five regions, alongside eight help videos. Of the 228 runs, 222 had a version made for a specific region, according to the company.

The work was carried out by AI coding agents, identified as Codex and Claude, from written plans. Meyer approved the plan, reviewed results and released each part, the account says. Agents worked in a separate code copy on their own branch. Films featuring the new app interfaces were held until Meyer reviewed the interface on Oct. 3, and paid reruns required his explicit approval. Apple’s developer agreement also required a human action: only Meyer could accept the updated Program License Agreement needed to unblock the iPhone build.

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 company reports 853 of 853 phone-app tests and 2,158 of 2,158 Studio tests passing. It says the website passed seven test suites and was checked in five regions at three screen widths. The web-app test suite still had eight failures across seven files; Gewerkton says six failures also occur on the main branch and one passes when run alone, so it attributes none to the redesign.

What the Relaunch Tested

The account offers a concrete example of how a company says it used coding agents on a multi-product release: agents handled implementation, while a person set the plan, checked the results and retained control over publishing and paid work. That division matters because the release involved more than a visual refresh. It touched mobile apps, a web product, a multilingual site and hundreds of generated film assets.

The reported problems also show where automated checks did not suffice. A first version of the icons appeared on white tiles that obscured adjacent labels in dark mode; Meyer spotted the issue visually, and the company says it corrected the icons and layout that evening. In film recolouring, automated masks missed red details in shadows and warm light. Gewerkton reports that visual review led it to clean 24 files and temporarily use the European cut for 10 regional versions; nine were later reshot with approval.

These details temper the headline claim of a two-day relaunch. The timeline describes execution from an approved plan, not design work beginning from a blank page, and the account says an interim design draft dated Sept. 26 was used. The metrics are the builder’s own figures, not an independent audit or evidence that the same schedule would apply to other products.

The Design Work Before Launch

Gewerkton says its HORIZON implementation started with a plan listing open decisions, options and recommendations. Meyer approved the recommendations before agents began work. When the plan proved unsuitable, the team logged deviations and chose what it described as the conservative option.

One example concerned the brand’s cobalt colour. Against a light background, the original shade reached a reported contrast ratio of 4.38:1, below Gewerkton’s stated working threshold of 4.5:1 under WCAG 2.1 AA. The company says it darkened the colour to reach 4.80:1 rather than ship the original shade. These are Gewerkton’s reported measurements and standard; the account does not provide an outside accessibility audit.

Film production added another layer of work. Gewerkton says it paused production after round nine, when 38% of jobs were failing and 208 of 228 runs were complete. The 76 failed jobs were not billed, according to the company. It also says 80 industry clips were redone after an initial image model made little change to faces. Its project records put the films’ actual cost at about $134, though the supplied account does not define which costs that figure includes.

“The relaunch execution ran from the approved plan to the live website on Oct. 2 and 3; an interim design draft dated Sept. 26 had already been carried into the work.”

Independent Checks Remain Absent

The performance figures, test results, upload count, film costs and production account come from Gewerkton, which was built by the publisher of the source report. No independent verification is supplied. The source also does not specify what is included in the roughly $134 film cost, how the figures were audited, or whether the reported checks were conducted by anyone outside the company.

Some defects remained after launch. Gewerkton reports that an Android test on a Pixel 10a found five major issues, including camera-screen buttons breaking words across lines after the redesign increased type size and padding. The company says none was a blocker and all five were scheduled for version 0.5.1. The account does not confirm whether that update has since shipped. The eight web-app test failures also remain part of the reported test record, even though Gewerkton says they were not caused by the redesign.

The account does not provide a complete independent assessment of accessibility, reliability across devices, or the quality of all regional film versions. It reports visual inspections and selected technical checks, but those do not establish how every user will experience the redesigned products.

Mobile Fixes and Film Review

According to Gewerkton, the next stated product step is version 0.5.1, which is scheduled to address the five major findings from the Pixel 10a Android test. The source account does not give a release date, so whether those fixes are already available remains unconfirmed.

The company says nine regional film runs were reshot after its visual review and passed another check. It also describes inspecting the middle frame of each of 157 mirrored films and reviewing reworked films again at 10%, 50% and 90% of their length. The published material does not say whether further regional replacements or revisions are planned.

Readers can expect any assessment of the relaunch’s longer-term performance to depend on updates to the apps and on evidence beyond the launch report, such as later release notes or independently checked results. For now, Gewerkton’s account documents what its team says it delivered, what failed during production and which issues it plans to address.

Key Questions

What did Gewerkton change during the relaunch?

Gewerkton says it applied the HORIZON design to its web app, iPhone and Android apps, Studio and 26 icons, and updated 529 website pages in 40 languages. It also reports 228 AI film runs for five regions.

Did the entire redesign begin and finish in two days?

No. Gewerkton says implementation and launch took place on Oct. 2 and 3, 2026, but an interim design draft from Sept. 26 was already available. The two-day claim refers to execution from the approved plan to the live website.

How were the AI agents supervised?

According to the company, Codex and Claude worked from written plans in a separate code branch. Thorsten Meyer approved the plan, reviewed the work and released each part. He also retained approval over paid film reruns and had to accept Apple’s developer agreement personally.

What went wrong during the work?

Gewerkton reports that white icon tiles obscured labels in dark mode, automated film masks missed some red details, and film jobs had a 38% failure rate at one point. An Android test also found five major issues, including buttons splitting words across lines.

Are the results independently verified?

No independent verification is included in the source material. The figures and test results are reported by Gewerkton, which the publisher says it built, and should be read as company-reported information.
