TL;DR
Gewerkton says AI coding agents implemented its HORIZON redesign across its web and phone apps, Studio, icons and a 529-page website on Oct. 2-3, 2026. The project’s publisher says humans approved plans and releases, caught visual defects, and held back some film versions; the redesign’s wider business impact has not been reported.
Gewerkton, a construction-site documentation tool built by Thorsten Meyer in Iffeldorf, Bavaria, replaced the look of its web app, iPhone and Android apps, Studio, icons and multilingual website with a design called HORIZON over Oct. 2-3, 2026, according to ThorstenMeyerAI.com’s account of the relaunch. Meyer says AI coding agents carried out the implementation from written plans, while he approved those plans, checked results and released each part. The change matters as a practical account of AI-assisted software work, but it is a self-reported case study: Gewerkton is built by the publisher, which disclosed that relationship.
The redesign covered the web app, phone apps, Studio and all 26 icons, alongside a website with 529 pages in 40 languages. The account says the web app’s 281 hard-coded colour values were moved to design tokens, except for 11 deliberate exceptions, and 47 cards were restyled. The phone app was updated to version 0.5.0 for iPhone and Android; the Studio received light and dark versions of the new look. All 26 icons were re-rendered in Blender using cobalt and navy.
The website received a new opening section featuring real product screens. Gewerkton reports that 1,583 files were uploaded without error. It also says the launch included 228 AI film runs for five regions, 222 with region-specific versions, and eight help videos. The company qualifies the two-day timeline: an interim design draft dated Sept. 26 was already available, so Oct. 2-3 describes execution from an approved plan to the live website, not the full design process.
Meyer’s account describes a staged workflow rather than an unrestricted instruction to redesign the products. A written plan listed open decisions, options and recommendations; Meyer approved the recommendations. Agents worked in a separate code copy on their own branch, and no part was merged or delivered until he released it. Films showing the apps were held until he had reviewed the new interface on Oct. 3, and paid film reruns required separate approval. Apple’s latest Program License Agreement also had to be accepted by Meyer before the iPhone build could proceed.
Human Checks Shaped the AI Relaunch
The account gives a concrete view of where AI agents contributed and where human oversight remained part of the process. Agents handled implementation from written plans, but approval, release decisions and visual inspection stayed with Meyer. Some work also depended on actions the agents could not take, including accepting Apple’s license agreement. The report therefore describes a supervised production workflow, not a fully autonomous product launch.
The reported defects show why that distinction matters. Automated checks did not catch white icon tiles that obscured adjacent labels in dark mode; Meyer spotted the problem by looking at the interface. A red-detection mask also missed helmet details in shadows and warm light, while some attempted recolouring altered faces or stickers. These examples do not establish how AI-assisted development performs across the industry, but they show that test results and automated image processing did not replace human review in this project.
For users, the immediate significance is a coordinated visual update across Gewerkton’s products and regional website, alongside a phone-app release. The source does not report user uptake, customer feedback, accessibility outcomes beyond one contrast adjustment, or a comparison with the time or cost of a human-only redesign. Those limits make the account useful as a description of process, rather than evidence of broader productivity gains.

A Draft Preceded the Two-Day Build
The two-day figure refers to the implementation and launch window on Oct. 2-3, 2026. The design had an interim draft from Sept. 26, and the work proceeded from an approved plan. This distinction matters: the account does not say the visual direction, planning and execution all began and finished in two days.
Gewerkton describes itself as a construction-site documentation tool built in Iffeldorf by Thorsten Meyer. The source says Meyer directed a fleet of Codex and Claude coding agents and personally approved plans and releases. Because the publisher also says it builds Gewerkton, the figures and account of the workflow are claims from an interested source, not independently verified results.
The reported checks included inspecting 200 web-app views across English, German, Japanese and Hindi, at widths of 390, 834 and 1,440 pixels, in light and dark modes. The phone app passed 853 of 853 tests and the Studio 2,158 of 2,158. The website passed seven test suites, followed by browser checks across five regions and a further run after upload. The source also says eight web-app tests failed across seven files; six files had the same failures on the main branch, and one failure depended on test order and passed when run alone. The account says the redesign neither caused nor fixed those failures.

Independent Results Remain Unreported
The account is published by the company’s builder, and the source material does not provide independent verification of the test results, file counts, film runs or timing. It also does not report customer response, adoption, sales effects, or whether the new design improved task completion or accessibility for users. The reported contrast adjustment is a project decision, not a full accessibility audit.
The source says production paused after round nine of film runs when 38% of jobs were failing, with 208 of 228 runs completed at that point. It reports that 76 failed jobs were not billed, but does not give enough detail to reconcile all run outcomes or explain the billing terms. A cost figure in the supplied account is cut off after “about 134 dollars actual”; without a complete explanation of what it covers, it cannot establish the total cost of the redesign or its return on investment.
Some film issues also remained in progress. After visual review, 24 files were cleaned and 10 regional versions with leftover red were temporarily switched to the European cut; nine were later reshot with Meyer’s approval and passed review. The source does not specify the final status of every version or provide a complete breakdown of the remaining film work.

Version 0.5.1 Targets Android Findings
Gewerkton says five major findings from an Android test are scheduled for phone-app version 0.5.1; none was classified as a blocker. One issue appeared on a Pixel 10a, where larger type and added padding caused camera-screen buttons to break mid-word, including a German cancel label that wrapped onto two lines. The account does not give a release date for version 0.5.1.
The source says nine regional film runs were reshot after review and passed a visual check, while some other regional versions had temporarily been replaced with the European cut. It does not set out a timetable for any remaining film changes. Further information on the phone-app update, final regional film versions and user response would help show what changed after launch.

Key Questions
What changed in Gewerkton’s HORIZON relaunch?
The reported update covered the web app, iPhone and Android apps, Studio, 26 icons and a 529-page website available in 40 languages. It also included AI-generated film runs and help videos.
Did AI agents complete the redesign without human involvement?
No. According to Meyer’s account, AI coding agents implemented the work from written plans, but Meyer approved the plan, reviewed results and released each part. He also approved paid film reruns and visually checked film outputs.
Was the entire redesign completed from scratch in two days?
No. The source says an interim design draft existed on Sept. 26, 2026. The two days on Oct. 2-3 refer to execution from an approved plan to the live website.
What problems were found during the relaunch?
Visual checks found icon tiles that obscured labels in dark mode and red details that an automated film mask missed. An Android test also found camera-screen buttons breaking across words; Gewerkton says five major Android findings are scheduled for version 0.5.1.
Are the reported results independently verified?
The supplied account comes from ThorstenMeyerAI.com, which discloses that its publisher builds Gewerkton. The source provides testing and production figures but no independent verification, customer-response data or measured business impact.
