TL;DR
Construction-site documentation tool Gewerkton replaced the look of its web and phone apps, Studio, icons and multilingual website with its HORIZON design on Oct. 2-3, 2026. Publisher ThorstenMeyerAI.com says AI coding agents handled implementation from approved plans, while Thorsten Meyer reviewed and released each part; the work included failures and manual fixes.
Gewerkton, a construction-site documentation tool, replaced the design of its web app, iPhone and Android apps, Studio, 26 icons and website with a new system called HORIZON on Oct. 2-3, 2026. Its publisher, ThorstenMeyerAI.com, says AI coding agents implemented the work from plans approved by founder Thorsten Meyer, who reviewed and released each part.
The publisher describes the two days as the execution period, not the full design process: an interim design draft dated Sept. 26 was carried into the work. The web app moved 281 hard-coded colour values into design tokens, with 11 exceptions retained, and 47 cards were restyled. The phone app was updated to version 0.5.0; the Studio received light and dark versions of the design.
The website spans 529 pages in 40 languages. The relaunch also included 228 AI film runs for five regions, 222 with regional versions, and eight help videos. The publisher says 1,583 files were uploaded without errors. It reports that nine regional film runs were later reshot with Meyer’s approval after visual checks found issues.
Agents worked in a separate copy of the code on their own branch. According to the account, Meyer approved the written plan and held release authority; films showing the apps were not approved until he had seen the interface on Oct. 3, and paid film reruns required his explicit approval. Apple also blocked an iPhone build pending acceptance of an updated Program License Agreement, a step only Meyer could take.

A New Chapter for Gewerkton
Two days of coordinated HORIZON implementation reshaped Gewerkton’s web and phone apps, Studio, icon set and multilingual website, with AI coding agents carrying out approved plans and Thorsten Meyer reviewing and releasing each part.
01 / Scope of the relaunch
One design system, many surfaces
HORIZON was applied across the construction-site documentation product and its public-facing materials. These are publisher-reported project records.
Hard-coded colour values moved into design tokens, with 11 exceptions retained. The team restyled 47 cards.
The iPhone and Android app received an update. Studio gained both light and dark versions of the HORIZON design.
The relaunch included AI film runs for five regions, eight help videos and 1,583 uploaded files, reported without errors.
02 / From draft to live release
Four stages, clear human gates
The account describes agents working in a separate copy of the code on their own branch, with the founder approving the plan and controlling release decisions.
Draft
An interim design draft was prepared on Sept. 26, before the two-day execution period.
Approve
The written plan listed open decisions and recommendations. Founder Thorsten Meyer approved the recommendations.
Implement & inspect
Agents implemented the changes. Meyer reviewed results; app films were held until he saw the interface on Oct. 3.
Release
Meyer released each part. Paid film reruns and Apple’s updated license acceptance also required his action.
03 / What the checks found
Automation helped; inspection caught more
The publisher reports broad test coverage, alongside visual defects that automated checks missed and test failures that remained in the record.
Reported tests passed for the phone app. An Android test also identified five findings scheduled for version 0.5.1; none was classified as a blocker.
All reported Studio tests passed across the work described in the account.
Eight tests in seven files failed. The publisher says six files failed the same way on the main branch and one failure depended on test order.
Visual review mattered
In dark mode, white icon tiles obscured labels. A red-colour detection mask missed film details in shadows and warm lighting. People found these issues by inspecting the interface and video frames.
Production was paused
After round nine, 38% of jobs were failing when 208 of 228 runs were complete. The account says nine regional film runs were later reshot with Meyer’s approval. It does not confirm the final status of every run.
04 / Reported coverage
A broad inspection matrix
The publisher says the web app was inspected across a combination of views, languages, widths and appearance modes.
The report does not specify that every possible combination was checked independently.
Across 228 reported AI film runs, 222 had regional versions. Production was paused amid failures, and the later reshoots followed visual checks and explicit approval.
The source also says 76 failed jobs were not billed. It does not explain the final disposition of all runs or give a complete project budget.
05 / Evidence & limits
What these figures can show
This is a first-party account from Gewerkton’s publisher, whose team says it builds the product and records what it learns.
| Reported item | What the account says | What remains open |
|---|---|---|
| Delivery window | Execution took place Oct. 2–3, 2026, from an approved plan. | The Sept. 26 draft shows preparation began earlier. |
| Film costs | About $134 in actual costs is introduced; 76 failed jobs were not billed. | The source cuts off before explaining the figure or its accounting scope. It is not a total redesign cost. |
| Follow-up | Five Android findings were scheduled for version 0.5.1. | No release date or confirmation that 0.5.1 shipped is provided. |
| Productivity claim | Project records describe a large coordinated implementation. | No independent audit or controlled human-only comparison establishes time or money saved. |
The report does not establish whether the web test failures have since been resolved. One Android finding involved camera-screen buttons breaking words across lines after larger type and padding were introduced; the German cancellation label wrapped to two lines.
06 / Key questions
What to take away
What changed?
HORIZON reached the web app, iPhone and Android apps, Studio, 26 icons and a 529-page website in 40 languages, alongside films and help videos.
Did agents release it on their own?
No. The publisher says Meyer approved the plan, reviewed outcomes and held release authority. Some steps required his direct action.
Was everything done in two days?
The reported execution window was Oct. 2–3. The interim design draft dates to Sept. 26, so the two-day description does not include all preparation.
What remains unconfirmed?
The final status of every film run, the full redesign cost, whether version 0.5.1 shipped and whether the web test failures were later resolved.
Human Gates in an AI Redesign
The account offers a specific example of AI agents carrying out a large, coordinated software and brand implementation, while people retained authority over design approval, visual review, spending and release. That distinction matters: the agents did not independently set the project’s goals or publish every result without oversight.
It also shows the limits of automated checks. Meyer says tests did not catch white icon tiles obscuring labels in dark mode, and a red-colour detection mask missed film details in shadows and warm lighting. People found those issues by inspecting the interface and video frames. The project therefore illustrates both the speed claimed for agent-assisted work and the review effort needed when visual quality is part of the deliverable.
The figures are the publisher’s project records, not an independently audited evaluation or a controlled comparison with a human-only workflow. They document this particular project, but do not establish how much time or money AI saved against another approach.

From Draft to Live Release
Gewerkton is built in Iffeldorf, Bavaria, by Thorsten Meyer, who says he directs a fleet of coding agents including Codex and Claude. ThorstenMeyerAI.com discloses that it is the publisher and that its team builds Gewerkton itself and records what it learns. The disclosure is relevant because the account is a first-party description of its own product work.
The project began before the two-day implementation window: an interim design draft was made on Sept. 26. For execution, the written plan listed open decisions, options and recommendations; Meyer approved the recommendations. When the original cobalt colour fell short of Gewerkton’s stated working contrast threshold—4.38:1 against a light background, below its 4.5:1 target—the team darkened it to 4.80:1 rather than ship the draft value.
The reported checks included web-app inspection 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, according to the publisher. The web app still had eight failing tests in seven files; the account says six files failed the same way on the main branch and one failure depended on test order.
“The two days cover the execution, from the approved plan to the live website.”

What the Project Figures Show
The account is a publisher’s own report; it does not provide an independent audit, a human-only comparison, or enough information to verify the reported productivity and quality measures externally. It also does not state the final status of every one of the 228 film runs after the pause and subsequent reruns.
The source material cuts off after introducing a cost figure for the films—about $134 in actual costs—without completing the explanation or specifying the accounting scope. That number should not be treated as the total cost of the redesign. The report says 76 failed jobs were not billed, but does not provide a full project budget or labour-cost estimate.
The web app’s eight test failures remain part of the reported record, even though the publisher says they were not introduced by the redesign. The report also says five major findings from an Android test were scheduled for version 0.5.1; it does not confirm that this later version has shipped.

Version 0.5.1 and Film Follow-up
Gewerkton’s account says five Android findings, none classified as a blocker, were scheduled for version 0.5.1. One involved camera-screen buttons breaking words across lines after larger type and padding were introduced; the German cancellation label wrapped onto two lines. The source does not give a release date for that update.
Further follow-up would clarify the final disposition of the film runs, the full cost behind the redesign and whether the web-app test failures have since been resolved. The publisher has not supplied a later status update in the source material, so those outcomes remain unconfirmed.

Key Questions
What changed in the Gewerkton relaunch?
The HORIZON design was applied to the web app, iPhone and Android apps, Studio, all 26 icons and a website covering 529 pages in 40 languages. The publisher also reports 228 AI film runs and eight help videos.
Did AI agents make and release the redesign without human review?
No. The publisher says agents implemented work from a written plan, while Thorsten Meyer approved the plan, reviewed results and released each part. Some steps, including paid film reruns and accepting Apple’s developer agreement, required his action.
Was the redesign completed entirely within two days?
The publisher says the execution ran on Oct. 2-3, 2026, but an interim design draft from Sept. 26 was used. The two-day description does not include all preparation.
Were there problems during the work?
Yes. Visual review found dark-mode icon tiles covering labels and film recolouring errors that automated checks missed. Film production was paused when 38% of jobs were failing after 208 of 228 runs; the publisher says failed jobs were not billed.
What remains unconfirmed?
The source does not confirm whether version 0.5.1 has shipped, give the final status of every film run, or provide a complete redesign budget. Its stated cost figure of about $134 is introduced without enough detail to establish what it covers.
