TL;DR
Gewerkton says it relaunched its web and phone apps, Studio, icons and multilingual website in a new design called HORIZON on 2–3 October 2026. Its publisher reports that AI coding agents carried out the planned implementation, while Thorsten Meyer approved releases and handled decisions the agents could not make. The account also records testing failures, visual defects and film-generation problems; the full project cost is not available in the supplied material.
Gewerkton, a construction-site documentation tool, replaced the look of its web and phone apps, Studio, icons and multilingual website with a design called HORIZON on 2–3 October 2026, according to its publisher, ThorstenMeyerAI.com. The publisher says AI coding agents carried out implementation from written plans, while creator Thorsten Meyer approved the plans, reviewed results and released each part.
The two-day description applies to execution, not the full design process: an interim draft dated 26 September was already available. The reported work covered a web app, iPhone and Android app version 0.5.0, Studio in light and dark modes, all 26 icons, and a website with 529 pages in 40 languages. The website also received a new opening section featuring product screens.
The company says developers converted 281 hard-coded colour values into design tokens, leaving 11 deliberate exceptions, and restyled 47 cards. The icons were re-rendered in Blender in cobalt and navy. The site’s 1,583 uploaded files reportedly completed without errors. Its film work comprised 228 runs for five regions, including 222 regional versions, plus eight help videos.
The publisher describes a gated workflow rather than a single instruction to redesign the product. Agents worked in a separate code copy and branch. Meyer approved a written plan listing open decisions, options and recommendations; the agents’ work was not merged or delivered until he released each part. Films showing the updated interfaces waited for his approval, and paid film reruns required explicit permission.

From Brand Rebuild To Relaunch: Gewerkton’s Two-Day AI Project
A broad HORIZON redesign reached release in two days of implementation, according to its publisher. AI coding agents did the planned work; Thorsten Meyer approved decisions, reviewed results and released each part.
The execution window was 2–3 October 2026. An interim design draft already existed on 26 September.
01 / Scope of the rebuild
One design across product and publishing
The publisher says the HORIZON refresh reached the web and phone apps, Studio, icons and multilingual website.
Web and phone apps
The web app was visually checked across screen sizes and languages. iPhone and Android app version 0.5.0 were included in the relaunch.
Light and dark modes
Studio was restyled, including 47 cards. The account reports 2,158 of 2,158 Studio tests passing.
Icons and 529 pages
All 26 icons were re-rendered in Blender in cobalt and navy. The 40-language website gained a new opening section with product screens.
The original cobalt measured 4.38:1 against the light background, below Gewerkton’s stated 4.5:1 working standard under WCAG 2.1 AA. It was darkened to 4.80:1.
02 / Human release gates
Agents implemented. A person held the keys.
The reported workflow divided execution from decisions and release authority.
Write the brief
Meyer approved a written plan listing open decisions, options and recommendations.
Work in isolation
Agents implemented tasks in a separate code copy and branch.
Inspect the results
Visual checks and testing surfaced defects that automated tests alone did not catch.
Approve each part
Work was not merged or delivered until Meyer released it. Paid film reruns needed explicit approval.
03 / Reported verification
Test totals and inspection findings
These are figures reported by Gewerkton’s publisher. The supplied account does not include independent verification.
Uploads: 1,583 files reportedly completed without errors.
Phone release: Version 0.5.0 was part of the relaunch.
Web tests: Eight tests failed across seven files; the account says these failures were not caused or fixed by the redesign.
Android review: Five findings on a Pixel 10a were slated for version 0.5.1; the account does not confirm shipment.
04 / Film production
Generation needed human review
Production covered five regions, with 222 regional versions and eight help videos in the reported work.
Round nine: 208 of 228 runs done
Production was paused when 38% of jobs were failing. The publisher says 76 failed jobs were not billed.
Colour changes were imperfect
Recolouring missed red objects in shadow and warm light. Other attempts altered faces or stickers. A dark-mode icon defect also escaped tests and was found in inspection.
Clean, substitute, reshoot
Twenty-four files were cleaned. Ten regional versions with remaining red were temporarily replaced by the European cut; nine were later reshot with Meyer’s approval.
Full project cost is unknown
The source mentions about $134 for films but cuts off before defining the amount’s scope. No complete redesign cost is provided.
05 / What remains open
Publisher claims, with limits
Gewerkton is built in Iffeldorf, Bavaria, by Thorsten Meyer, who says he directs AI coding agents from Codex and Claude.
Version 0.5.1 is pending
One documented issue: larger type and extra padding made the German word for “cancel” wrap across two lines on camera-screen buttons. No release date is given.
Eight failures remain described
Six files reportedly fail the same way on the main branch; another failure depends on test order and passes alone. Test names and an independent assessment are not supplied.
Final regional coverage is unclear
The account does not confirm that every remaining film or regional version has been reviewed or replaced.
First-party account
The publisher also builds Gewerkton and writes about the work. Test results, film quality and product performance are not independently verified in the supplied material.
Human Gates in an AI Relaunch
The account offers a detailed example of how a small software publisher used coding agents for a broad product refresh while reserving consequential decisions for a person. Plan approval, release approval and visual review remained with Meyer; the agents handled implementation tasks within those limits. This matters to users because a redesign touches the interface, accessibility, regional content and app-store distribution, not just the product’s appearance.
The publisher’s figures also show why automated tests alone did not establish that the relaunch was ready. A dark-mode icon defect escaped tests and was found through inspection. Film recolouring missed red objects in shadow and warm light, while other attempts altered faces or stickers. Meyer’s account says the defects were corrected or the affected versions were held back, but it is a publisher’s report, not an independent audit of the process or its outcomes.
Accessibility was part of the reported decision-making. The original cobalt colour reached a contrast ratio of 4.38:1 against the light background, below Gewerkton’s stated 4.5:1 working standard under WCAG 2.1 AA. The colour was darkened to 4.80:1 rather than shipped unchanged. That is a concrete example of a design recommendation being adjusted during implementation.

From Draft to Live Release
Gewerkton is built in Iffeldorf, Bavaria, by Thorsten Meyer, who says he directs AI coding agents from Codex and Claude. The source account discloses that Gewerkton is built by the publisher, which also writes about the work. Its operational figures and descriptions should therefore be read as first-party claims, rather than independently verified measurements.
The project began before the two-day execution window: a draft of the new look existed on 26 September. On 2 October, the approved plan guided implementation; the relaunch work concluded on 3 October. Some steps depended on human action outside the agents’ authority. Apple blocked the iPhone build pending acceptance of its latest Program License Agreement, which only Meyer could accept.
Testing covered multiple screen sizes and languages. The web app was visually checked across 200 views, in English, German, Japanese and Hindi, at widths of 390, 834 and 1,440 pixels, in light and dark modes. The publisher reports 853 of 853 phone-app tests and 2,158 of 2,158 Studio tests passing, as well as seven of seven website test suites passing. It also says the live website was checked again after upload.
““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, Defects and Verification
The source says the project records give one actual cost figure for the films—about $134—but the supplied material cuts off before explaining its scope. It is unclear whether that amount covers all film-generation costs, only a particular component, or excludes staff time and other project expenses. No complete cost for the redesign is provided.
The publisher reports that eight web-app tests failed in seven files. Six files reportedly fail in the same way on the main branch, while one failure depends on test order and passes when run alone. The redesign did not cause those failures, according to the account, but did not fix them either. The source does not provide the individual test names or an independent assessment of that explanation.
The publisher says five major findings from an Android test on a Pixel 10a were not release blockers and were scheduled for version 0.5.1. The supplied account does not specify all five findings or confirm that the update has shipped. It also does not provide independent verification of the stated test results, film quality or performance of the relaunched product.

Android Fixes and Film Review
According to the publisher, the five Android findings are slated for version 0.5.1. One documented issue affects camera-screen buttons: larger type and added padding caused the German word for “cancel” to wrap across two lines. The source does not give a release date for the update.
Film production was paused after round nine, when 208 of 228 runs had been completed and 38% of jobs were failing. The publisher says the 76 failed jobs were not billed. After visual review, 24 files were cleaned, 10 regional versions with remaining red were temporarily replaced with the European cut, and nine of those runs were later reshot with Meyer’s approval. The account does not state whether every remaining film or regional version has since been reviewed or replaced.
The immediate next milestones described are the Android fixes and continued handling of regional film versions. Any broader assessment of the relaunch will depend on what the publisher reports about version 0.5.1, outstanding test failures and the final status and cost of the film work.
