TL;DR
Gewerkton says it replaced the design across its web and phone apps, Studio, icons and multilingual website on Oct. 2–3, 2026, using AI coding agents to implement a plan approved by its publisher. The company reported extensive testing and human review, while also documenting failures and fixes; the project’s reported film costs and longer-term results remain unclear.
The new design, called HORIZON, covered the product’s web and phone apps, Studio in light and dark modes, all 26 icons and a website with 529 pages in 40 languages. Gewerkton said its website received 1,583 files without an upload error, and that it produced eight help videos alongside the regional films. The publisher disclosed that it builds Gewerkton and is reporting on its own work.
The company’s account qualifies the “two days” description: an interim design draft dated Sept. 26 was already available. The stated two-day period refers to execution from an approved plan through the live website, not design work starting from scratch. Of 228 film runs, 222 had regional versions of their own, according to the project records.
Gewerkton said the web app’s 281 hard-coded color values were moved to design tokens, with 11 exceptions retained, and 47 cards were restyled. It reported that the phone app was updated to version 0.5.0. A contrast check also led to a small change: the planned cobalt color measured 4.38:1 against a light background, below the company’s stated 4.5:1 working standard, so it was darkened to 4.80:1.
Product relaunch / October 2026
Gewerkton’s Two-Day Makeover
A relaunch built with AI agents brought the HORIZON design across Gewerkton’s apps, Studio, icons and multilingual website. The publisher reports extensive tests and human review, alongside defects, fixes and open questions about cost and follow-up work.
One design, many surfaces
Gewerkton says HORIZON unified the product experience across web, mobile, Studio and the public site.
Web app
281 hard-coded color values moved to design tokens, with 11 exceptions retained. The redesign also restyled 47 cards.
iPhone + Android
The phone app was reported updated to version 0.5.0. A Pixel 10a review later surfaced five major issues slated for 0.5.1.
Light + dark modes
Studio received the HORIZON treatment in both modes, as part of a coordinated redesign across the product.
26 icons
The full icon set was included in the relaunch, extending the visual system beyond screens and pages.
Multilingual website
The live site contains 529 pages in 40 languages. Gewerkton reports uploading 1,583 files without an upload error.
Regional films + help
Records show 228 AI film runs, including 222 with regional versions of their own, plus eight help videos.
Agents implemented. People approved.
The publisher describes a supervised workflow with written plans, a separate code branch and human release decisions.
Open decisions, options and recommendations were written down before implementation.
Thorsten Meyer approved the plan; deviations were logged and conservative options used.
Codex and Claude worked in a separate code copy and on their own branch.
Meyer reviewed results and released each part. Paid film reruns also needed approval.
Reported checks—and what they found
Automated results were extensive, but visual review caught problems the scans missed.
200 views checked
English, German, Japanese and Hindi at 390, 834 and 1,440 px, in light and dark modes. No overflow or console errors were reported.
853 / 853 tests passed
The reported phone-app test suite passed in full during the relaunch account.
2,158 / 2,158 passed
Studio tests passed in full, alongside seven website test suites and a live-site check after upload.
Eight web-app tests failed across seven files. Gewerkton says six files failed the same way on the main branch; one failure depended on test order and passed alone. The publisher says the redesign caused none of them, and they were not fixed in this work. Results have not been independently verified.
Small measurements, visible decisions
Some project details show how review translated into concrete changes.
The planned cobalt fell below the stated 4.5:1 working standard, so it was darkened. Review also found red details that escaped an automated mask; nine regional film runs were later reshot with Meyer’s approval.
Open questions remain
The publisher’s account documents work and reported results, but leaves several outcomes unresolved.
“About $134 actual”
The figure appears in the film-cost account, but its scope, currency basis and calculation are not explained. It is unclear whether it covers all 228 runs. No full project budget or non-agent comparison is provided.
Paused after round nine
Production paused when 38% of jobs were failing. By then, 208 of 228 runs were complete; the publisher says 76 failed jobs were not billed. Final status for every film is not detailed.
Five major findings
A Pixel 10a test found issues including camera-screen buttons breaking across words after type size and padding increased. Gewerkton scheduled all five for version 0.5.1.
Publisher reporting on its work
Thorsten Meyer builds Gewerkton and reported on the relaunch. The account is not an independent evaluation of agent performance, cost or productivity.
What the two-day claim covers
A useful distinction between the earlier design work and the reported execution window.
How the Agent Workflow Was Controlled
The project offers a concrete account of how one small software publisher used coding agents for a broad, coordinated product redesign. Gewerkton says the agents worked in a separate code copy and on their own branch, and that no part was merged or delivered before Meyer released it. That makes the reported workflow less an automated, unsupervised launch than a human-approved implementation process.
Some decisions remained explicitly with Meyer. Films showing the apps were held until he had reviewed the new interface on Oct. 3, and paid film reruns required his approval. Apple’s developer agreement also had to be accepted by a person before the iPhone build could proceed. The company’s account shows that using agents did not remove platform requirements or human sign-off.
The relaunch may interest product teams considering similar tools because it includes both reported output and the work needed to catch defects. Automated tests were part of the process, but visual inspection found problems the tests missed. The account is a publisher’s description of its own project, not an independent evaluation of agent performance, cost or productivity.

A Design Draft Preceded Launch
Gewerkton describes itself as a construction-site documentation tool developed in Iffeldorf, Bavaria, by Thorsten Meyer. For the relaunch, the work began from a written plan that listed open decisions, options and recommendations. Meyer said he approved the recommendations before agents implemented the changes, with deviations recorded and conservative alternatives used when the plan did not hold up.
The company said the web app was checked across 200 views in English, German, Japanese and Hindi, at widths of 390, 834 and 1,440 pixels, in light and dark modes. It reported no overflow or browser-console errors in those checks. The phone app passed 853 of 853 tests, the Studio passed 2,158 of 2,158, and the website passed seven test suites; the live site was also checked after upload.
Those results did not mean every test was clear. Gewerkton reported eight failing web-app tests across seven files. It said six files failed in the same way on the main branch and one failure depended on test order and passed when run by itself. The company attributed none of those failures to the redesign, while acknowledging they were not fixed as part of it.
““Two days” needs one qualification. An interim draft of the look from 26 September was carried into the work, so the design did not start from nothing on 2 October.”

Costs and Defects Still Need Detail
The supplied project account begins a cost section by saying the film records show “about 134 dollars actual” cost, but the figure’s full scope, currency basis and calculation are not provided. It is not clear whether that amount covers all 228 runs, only a portion of production, or other associated work. No complete project budget or comparison with a non-agent workflow is stated, so the account does not establish overall savings.
Gewerkton reported that film production paused after round nine when 38% of jobs were failing; by then, 208 of 228 runs were complete, and it said 76 failed jobs were not billed. It also described correcting visual problems, including red details that escaped an automated mask. The account says nine regional runs were later reshot with Meyer’s approval, but does not provide a full accounting of the final status of every film.
Some product issues remain open. The Android test on a Pixel 10a found five major issues, including camera-screen buttons breaking across words after the redesign increased type size and padding. Gewerkton said none was a blocker and scheduled all five for version 0.5.1; the account does not confirm when that release will ship. Independent verification of the reported test results is not included.

Version 0.5.1 and Film Rechecks
Gewerkton said it plans to address the five findings from its Android test in version 0.5.1. The company has not provided a release date in the available account. Readers will need a later update to confirm when that version is issued and whether the camera-screen layout and other findings have been corrected.
The project account also says nine film runs were reshot after regional versions retained red elements, following an earlier visual review and approval from Meyer. It does not set out a date for further film work or describe a separate, independently conducted review of the completed relaunch. The publisher’s next useful update would clarify the final film status and provide the complete cost figure and its scope.
For now, the documented outcome is a completed HORIZON rollout across Gewerkton’s listed products and site, along with tests, human review and fixes reported by the publisher. The remaining questions concern the full cost, the final status of all film versions and when the planned Android corrections will reach users.

Key Questions
What changed in Gewerkton’s relaunch?
Gewerkton says the HORIZON design was applied to its web app, iPhone and Android app, Studio, all 26 icons and a 529-page website available in 40 languages. The rollout took place on Oct. 2–3, 2026.
What role did AI agents play?
According to the publisher, AI coding agents Codex and Claude implemented work from written plans on a separate code branch. Thorsten Meyer approved the plan, reviewed results and released each part; some decisions and platform steps required human approval.
Did the project really start and finish in two days?
The reported execution ran across Oct. 2 and 3, but Gewerkton says an interim design draft existed from Sept. 26. Its “two days” refers to implementation from an approved plan through the live website, not the full process from initial design.
What problems did the relaunch uncover?
Gewerkton reported that icon tiles obscured labels in dark mode and that an automated film-color mask missed some red details, among other issues. It also reported eight web-app test failures it said were already present or dependent on test order, plus five Android findings scheduled for version 0.5.1.
How much did the film production cost?
The available account starts to report an actual cost of about $134, but does not provide enough information to establish what the figure covers. It should not be treated as the complete cost of all film production without that missing detail.
