TL;DR
Gewerkton replaced the look of its web and phone apps, Studio, icons and multilingual website with a design called HORIZON on Oct. 2–3, 2026. The publisher says AI coding agents carried out the implementation from approved plans, while Thorsten Meyer reviewed and released each part; testing also exposed visual problems and remaining app fixes.
Gewerkton, a construction-site documentation tool, replaced the design of its web app, iPhone and Android apps, Studio, 26 icons and multilingual website with a new system called HORIZON on Oct. 2–3, 2026. The publisher says the original analysis describes AI coding agents implementing the changes from plans approved by founder Thorsten Meyer, who reviewed and released each part.
The two-day timeframe refers to implementation, from an approved plan to the live website. An interim design draft dated Sept. 26 was already available, so the work did not begin from a blank page on Oct. 2. The relaunch also included 228 AI film runs for five regions and eight help videos.
In the web app, the team moved 281 hard-coded colour values into design tokens, left 11 deliberate exceptions and restyled 47 cards. The phone app moved to version 0.5.0 in the new look. Studio received light and dark versions; all 26 icons were re-rendered in Blender. The website’s 529 pages in 40 languages received a new opening section featuring product screens, and the publisher reports uploading 1,583 files without an error.
The publisher says the agents worked on a separate code copy and branch, and changes were not merged or delivered until Meyer released them. Some actions remained human-controlled: Meyer approved films showing the redesigned interfaces, authorized paid film reruns and accepted Apple’s latest Program License Agreement, which Apple required before the iPhone build could proceed.
Human review shaped the rollout
The relaunch is a concrete account of how one small software publisher used AI agents for a broad, multi-product implementation while retaining human approval gates. The agents handled code and production tasks, but the account describes Meyer as approving the plan, inspecting results and deciding what went live. The publisher’s disclosure matters: Gewerkton is built by Thorsten Meyer, and the account comes from the publisher’s own site, not an independent audit.
The reported checks also show why passing automated tests was not treated as sufficient. The web app was inspected across 200 views, four languages, three screen widths and light and dark modes. The phone app passed 853 of 853 tests, and Studio passed 2,158 of 2,158. But a dark-mode icon problem and film recolouring errors were found by visual review rather than tests. For readers evaluating claims about AI-assisted software work, the account offers both reported output and examples of where human inspection caught defects.

What the two-day count covers
Gewerkton is built in Iffeldorf, Bavaria, by Meyer, who says he directs a fleet of AI coding agents from Codex and Claude. The relaunch account describes a planned workflow rather than an open-ended request to redesign the product: a document listed unresolved decisions, options and recommendations, and Meyer approved the recommendations before implementation.
The schedule also had practical limits. The design draft existed from Sept. 26, and the two-day measure starts with the approved plan and ends with the live website. The work included a change to the original palette: cobalt against a light background measured 4.38:1, below Gewerkton’s stated 4.5:1 working standard under WCAG 2.1 AA. The team darkened the colour, reporting a revised contrast ratio of 4.80:1.

Limits of the reported checks
The results and testing figures come from the publisher’s own account; the material provided does not include an independent review of the code, tests, accessibility measurements or production records. Gewerkton reports eight failing web-app tests across seven files. Six files reportedly fail in the same way on the main branch, and another test passes when run alone, so the company says these failures were not caused by the redesign. The account also says the redesign did not fix them.
Film production had a separate quality problem: after round nine, work paused when 38% of jobs were failing, with 208 of 228 runs complete. The 76 failed jobs were not billed, according to the publisher. The supplied source ends during a section on costs and provides only an approximate figure of $134 in actual film costs; it does not give a complete cost breakdown for the whole relaunch or explain all exclusions. It is also unclear from the account whether every remaining interface issue has since been resolved.

Android fixes are due in 0.5.1
Gewerkton says five major findings from an Android test on a Pixel 10a are scheduled for version 0.5.1, with none classified as blockers. One example was a camera-screen button whose larger type and padding caused the German word for “cancel” to wrap onto two lines. The account does not provide a release date for that version.
The publisher also reports that nine regional film runs were later reshot with Meyer’s approval and passed visual review; 10 versions containing leftover red were temporarily switched to the European cut. The account does not say whether every regional replacement has now been completed. Further updates to the apps and film set will show how the reported follow-up work proceeds.

Key Questions
What changed in Gewerkton’s relaunch?
The HORIZON design was applied to the web app, iPhone and Android apps, Studio, all 26 icons and a 529-page website available in 40 languages. The publisher also reports 228 AI film runs across five regions and eight help videos.
Did AI agents complete the redesign without human involvement?
No. Gewerkton says AI coding agents implemented work from written plans, while Thorsten Meyer approved the plan, reviewed results and released each part. He also approved certain film reruns and completed an Apple agreement required for the iPhone build.
What went wrong during the rollout?
Visual review found white icon tiles that obscured labels in dark mode, and automated film masks missed some red details or recoloured other areas incorrectly. The publisher also reports a production pause when 38% of film jobs were failing and five non-blocking Android findings scheduled for version 0.5.1.
Was the work completed entirely from scratch in two days?
No. Gewerkton says an interim design draft dated Sept. 26, 2026 was carried into the work. The two-day period describes execution from the approved plan through the website’s launch on Oct. 2–3.
How much did the relaunch cost?
The supplied account gives an approximate actual cost of $134 for the films, but the source material ends before providing a full breakdown. It does not establish the total cost of the redesign or all work involved.
