Gewerkton, a construction-site documentation tool, replaced the look of its web and phone apps, Studio, icons and multilingual website on Oct. 2 and 3, 2026, in a relaunch called HORIZON, as detailed in the original analysis. The company says AI coding agents carried out the implementation from written plans, while founder Thorsten Meyer approved the plan, inspected the results and released each part.

Gewerkton says the redesign moved 281 hard-coded web-app color values to design tokens, with 11 exceptions retained, and restyled 47 cards. The iPhone and Android app moved to the new look in version 0.5.0; the Studio received light and dark themes. All 26 icons were re-rendered in Blender, and the website’s 529 pages across 40 languages received a new opening section featuring real product screens. Gewerkton reports uploading 1,583 files without an error.

The relaunch also included 228 AI film runs for five regions, 222 with a regional version, and eight help videos. Gewerkton qualifies the two-day framing: an interim design draft dated Sept. 26 was carried into the work, so the design did not begin from scratch on Oct. 2. The two days refer to execution from the approved plan through the live website.

The company describes a staged process rather than an unrestricted agent task. Meyer approved a written plan listing decisions, options and recommendations; the agents worked in a separate code copy and branch. No part was merged or delivered until Meyer released it. Films showing the redesigned products were held until he had reviewed the interface on Oct. 3, and paid film reruns required explicit approval. Apple also blocked the iPhone build pending acceptance of its latest Program License Agreement, a step only Meyer could complete.

Human Review Shaped the Relaunch

The project offers a specific example of a small software publisher using AI agents to implement a coordinated redesign across multiple products and a multilingual site. Gewerkton’s account is a first-party description from its publisher, not an independent assessment of how much time or labor the agents saved. The company’s disclosed workflow shows that agent-led implementation still relied on written specifications, human release decisions and checks that automated tests could not replace.

Those checks affected what shipped. Gewerkton says its original cobalt color fell short of its working contrast target: 4.38:1 versus 4.5:1 under its WCAG 2.1 AA standard. It darkened the color to reach 4.80:1 rather than release the planned shade. Visual inspection also caught icon tiles that obscured labels in dark mode and red details left in regional films after automated recoloring. The incidents illustrate why a successful test run alone did not establish that every change looked right.

For users, the change affects the interface across web, mobile and Studio, while the films present the product in regional versions. Gewerkton says the redesign passed its stated checks in several languages, screen widths and display modes. That is useful operational detail, but it remains the company’s own report; the source does not provide outside verification or user-response data.

From Draft to Live HORIZON

Gewerkton is built in Iffeldorf, Bavaria, by Thorsten Meyer, who directs coding agents identified by the publisher as Codex and Claude. The company says the HORIZON work began with a draft dated Sept. 26, followed by planning and implementation that culminated in the live redesign on Oct. 2–3. This distinction matters because the announced “two days” describe execution, not the entire design process.

The publisher reports checks for the web app across 200 views, four languages—English, German, Japanese and Hindi—and widths of 390, 834 and 1,440 pixels, in both light and dark mode. It says there was no overflow or console error in that inspection. The phone app passed 853 of 853 tests, Studio passed 2,158 of 2,158, and the website passed seven test suites, with browser checks across three widths and five regions.

Those results were not uniformly clean. Eight web-app tests failed across seven files; Gewerkton says six files failed the same way on the main branch and another failure depended on test order and passed when run alone. The company says the redesign did not cause those failures, but also did not fix them. For film quality, it relied on people: the middle frame of each of 157 mirrored films was inspected, and reworked films were watched again at 10%, 50% and 90% of their length.

““The two days cover the execution, from the approved plan to the live website.””

— Gewerkton, in the publisher’s project account

What the Project Account Leaves Open

The account comes from Gewerkton’s publisher, which disclosed that it built the product itself. The provided material does not include an independent audit of the reported test results, the agents’ work, or the time and labor required. It also does not say how customers have responded to HORIZON or whether the redesign changed product usage.

Some project details remain incomplete. The source cuts off after saying the film records contain “one real figure: about 134 dollars actual,” without clarifying the accounting scope or providing the rest of the cost information. The basis for that figure should not be inferred. Gewerkton also reports that nine regional film runs were later reshot with Meyer’s approval, but does not give a final overall count of accepted runs or explain the lasting plan for the regional versions temporarily replaced by European cuts.

The web-app test failures were described as unrelated to the redesign, but the account does not identify the tests or say when they will be addressed. The five major findings from the Pixel 10a Android test are likewise not individually described beyond a button-label wrapping problem; the company says none blocked release.

Android Fixes and Film Follow-Up

Gewerkton says the five major findings from the Pixel 10a Android test are scheduled for version 0.5.1. One identified issue is that larger type and added button padding cause text on the camera screen to break mid-word; the German cancel label wraps onto two lines. The publisher did not provide a release date for version 0.5.1.

The film work included a pause after round nine, when Gewerkton reported that 38% of jobs were failing and 208 of 228 runs had been completed. The company says 76 failed jobs were not billed. After visual review, 24 files were cleaned and 10 regional versions with remaining red details were temporarily switched to the European cut; nine were later reshot and visually checked. The source does not state when any remaining regional replacements will be completed.

Beyond those follow-up items, the publisher has not announced another HORIZON milestone or independent review. The next public indicators will be whether the scheduled Android fixes ship and whether Gewerkton reports further updates to the regional films or the web-app tests.

Key Questions

What did Gewerkton change in the HORIZON relaunch?

Gewerkton says it updated the design of its web app, iPhone and Android app, Studio, 26 icons and website. Its website covers 529 pages in 40 languages, and the project also included 228 film runs for five regions and eight help videos.

Were AI agents responsible for the entire redesign?

The publisher says AI coding agents implemented the approved plans. Thorsten Meyer approved the plan, reviewed results and released each part; he also handled decisions agents could not make, including Apple’s license agreement acceptance and approval of paid film reruns.

Did the work really take only two days?

The live execution ran on Oct. 2 and 3, 2026, according to Gewerkton. The company says an interim design draft from Sept. 26 was used, so “two days” does not mean the design started from nothing on Oct. 2.

Were there problems during the relaunch?

Yes. Gewerkton reports dark-mode icon tiles that obscured labels, film recoloring that missed or damaged details, and a high rate of failed film jobs that led to a production pause. It also identified an Android camera-screen button wrapping issue slated for version 0.5.1.

How much did the project cost?

The supplied account is incomplete: it ends after saying the film records show “about 134 dollars actual” and does not explain what that amount covers. No fuller project cost can be established from the provided material.
