Gewerkton, a construction-site documentation tool, says it replaced the look of its web app, iPhone and Android apps, Studio, 26 icons and multilingual website with a design called HORIZON during work on October 2–3, 2026. The company says AI coding agents completed the implementation from written plans, while founder Thorsten Meyer approved the plans, checked results and released each part, as detailed in the original analysis.

The update covered 529 website pages in 40 languages, a new opening section featuring product screens and 1,583 uploaded files. Gewerkton also says the phone app moved to the new look in version 0.5.0, and the Studio received light and dark versions. In the web app, 281 hard-coded colour values were moved into design tokens, with 11 exceptions retained, and 47 cards were restyled. The 26 icons were re-rendered in Blender using cobalt and navy.

The company reports that its website passed seven of seven test suites and was checked at three screen widths across five regions, both before and after upload. The phone app passed 853 tests and the Studio passed 2,158. The web app was visually inspected in 200 views across four languages, three screen widths and light and dark modes. Gewerkton says those checks found no overflow or console errors in the reviewed views.

Those results did not mean every test was green. Gewerkton says eight web-app tests failed in seven files; six files also fail on the main branch, while another test depends on run order and passes when run alone. The company says the failures were not caused by the redesign, but were not fixed by it either. Meyer also checked the films visually, including middle frames from 157 mirrored films and reworked films at several points in their duration.

Human Checks Shaped the AI Rollout

The relaunch offers a specific example of how a small software company says it used AI coding agents for a multi-part release without handing them final authority. Gewerkton describes the agents as implementing approved plans in a separate code copy and branch. Meyer reviewed work before merging or release, and certain actions—including accepting an Apple developer agreement and approving paid film reruns—required his direct involvement.

The reported defects also show why automated coding and test results are not the same as a finished product. A dark-mode icon issue escaped tests and was found by looking at the interface. Automated colour masks missed red details in film footage, while other recolouring attempts altered faces or objects incorrectly. For readers evaluating AI-assisted software work, the account points to the importance of visual review, release gates and clear human responsibility, alongside test counts.

A Design Draft Came Before October

The two-day description has a qualification: Gewerkton says an interim design draft dated September 26 was already available. October 2–3 describes the execution from an approved plan to the live website, rather than the entire design process starting with a blank page and finishing in two days.

Gewerkton is built in Iffeldorf, Bavaria, by Thorsten Meyer, who directs AI coding agents identified in the source as Codex and Claude. The publisher of the source account discloses that it builds Gewerkton itself and documents what it learns. The performance and cost figures here are therefore the company’s own account, not an independently audited assessment.

Independent Verification Remains Unclear

The detailed release, test and production figures come from Gewerkton’s own account. The source does not provide independent verification of the reported test runs, upload totals, quality checks or overall time spent on the redesign. It also does not give a complete accounting of the project’s costs: the supplied material says film records show about $134 in actual costs, but provides no fuller cost breakdown or comparable figure for the rest of the work.

The source says 228 film runs were made for five regions, with 222 having a regional version of their own, alongside eight help videos. It reports a pause after round nine when 38% of jobs were failing, with 208 of the 228 runs completed and 76 failed jobs not billed. The account does not fully explain how those counts relate to one another. It says nine regional runs were later reshot with Meyer’s approval, but does not specify the final total of completed, accepted films for each region.

Version 0.5.1 Addresses Android Findings

Gewerkton says five major findings from an Android test on a Pixel 10a are scheduled for phone-app version 0.5.1. None was classified as a blocker. One issue involved buttons on the camera screen: larger type and added padding caused text to break mid-word, including the German word for “cancel,” which wrapped onto two lines.

The source does not provide a release date for version 0.5.1 or further detail on the other four findings. Gewerkton’s next reported milestone is therefore the planned app update; whether additional fixes or changes to the regional films will follow is not stated.

Key Questions

What changed in Gewerkton’s HORIZON redesign?

Gewerkton says it updated its web app, iPhone and Android apps, Studio, 26 icons and 529-page website. The website spans 40 languages, and the phone app’s new design is in version 0.5.0.

Did the redesign really start and finish in two days?

The company says the implementation and relaunch took place on October 2–3, 2026, but an interim design draft dated September 26 had already been prepared. The two-day claim applies to execution from an approved plan to the live website.

What did the AI agents do, and what did Meyer approve?

According to Gewerkton, AI coding agents carried out implementation from written plans in a separate code branch. Founder Thorsten Meyer approved the plans, reviewed results and released each part; some steps, including approval of paid film reruns, remained subject to his explicit sign-off.

Were there problems after the redesign?

Yes. Gewerkton reports eight web-app test failures that it says were not caused by the redesign, as well as issues found through visual review, including white icon tiles covering nearby labels in dark mode. An Android test also found camera-screen button text wrapping; five major findings are scheduled for version 0.5.1.

How much did the project cost?

The supplied account gives one cost figure: about $134 in actual costs for the films. It does not provide a full budget for the redesign or a breakdown of costs across the apps, website and other work.
