Thorsten Meyer says he built Altersteilzeit, a free web app for people counting down to partial retirement in Germany, with help from an AI coding agent over five days. The project grew from a request for a one-minute animated film into a site with a daily working-day countdown, a short narrated film and 19 3D games, according to Meyer’s October 13 account on ThorstenMeyerAI.com.

Meyer said he began the project on September 28, 2026, asking the agent for a short film about the block model of German Altersteilzeit. In that arrangement, a person works during an active phase and is then released from work for a matching passive phase. The app lets users enter a date and choose a model from 1:1 to 5:5; it calculates the corresponding dates and remaining workdays.

The finished site combines that calculation with a morning dashboard showing the countdown, milestones and a daily saying. Meyer also described calendar exports, a printable calendar, a bridge-day finder and a film depicting the shift from working life to time off. The game section, he said, has 19 ways to play, with each year of the active phase represented as a level. His account also lists seven languages, five German dialects, a team countdown and badges.

Meyer reported that the work spanned 24 commits, each co-authored by Claude Opus 5.5 as a coding agent. He said the agent handled coding, testing, translation work, voice clips and deployment. Meyer says he supplied the idea and creative direction, made decisions such as choosing voices and dialects, checked the results and approved releases. These project details come from his own account; no independent technical audit or usage figures were provided.

A Countdown App With Human Direction

The project offers a specific example of how a person may use an AI coding agent to turn a small software request into a larger public-facing product. Meyer’s account describes more than code generation: the agent also supported testing, translation, audio production and deployment. At the same time, he portrays the work as a collaboration in which product choices and release approval stayed with him.

For people approaching partial retirement, the app is designed to make a long wait more tangible through daily counts, milestones and games tied to the calendar. Meyer says it is free and has no accounts, cookies or tracking, with calculations performed in the browser. The practical value will depend on whether its date calculations and regional holiday settings work reliably for users, an area for which the account gives no independent evaluation.

From Film Request to Public App

The app is based on the German Altersteilzeit block model, which separates an active work period from a passive period of equal length. Meyer says users enter the start of either phase, select a model and supply leave information. The app then counts weekdays while subtracting public holidays for the selected German federal state and the leave entered by the user.

Meyer’s timeline places the expansion across five days. The first day brought the film concept, date calculations and early game prototypes; later days added the dashboard, languages, additional games, badges, sound and narration. He reports that the site was online on the first evening, with further features and refinements added before he approved the release on October 2. The project’s title, “From 16 Versions to 19 Games,” refers to an earlier stage of the build, though his account does not explain what the 16 versions counted.

According to Meyer, the games use calendar time as their structure: weeks and months map to levels, and entered leave can affect gameplay. He also says the project uses names intended to avoid other companies’ trademarks. Those descriptions explain the design, but the article does not provide external testing results or evidence of how users have received the app.

““It started as a one-minute film. Five days later it was a daily countdown, nineteen 3D games, a narrator in twelve languages and a public website.””

Questions on Accuracy and Adoption

Meyer’s account does not include an independent review of the app’s calculations, security or accessibility, nor does it report downloads, visitor numbers or user feedback. It is not clear how the site handles edge cases in regional holiday calendars or whether its features have been tested with people using different employment arrangements.

There is also a discrepancy in the description of the games: the overview says the app offers 19 ways to play, while the timeline says the initial game had fifteen modes before further development. Meyer’s account does not specify whether the final total of 19 refers to distinct games, modes or both. The headline’s reference to “16 versions” is likewise not explained in the text supplied.

Further Testing and User Response

Meyer’s article describes the app as public by October 2, but it does not announce a scheduled update, a next release date or plans for future features. The next developments to watch are whether the site receives user feedback, how Meyer responds to any reported calculation or usability problems, and whether he publishes further information about the app’s performance.

Readers considering the countdown should check that the dates, selected federal state and entered leave match their own circumstances. Meyer says the app calculates dates in the browser, but the source account does not present an external verification of its results.

Key Questions

What is Altersteilzeit?

Altersteilzeit is a German form of partial retirement. In the block model described by Meyer, a person works through an active phase and is then released from work for a matching passive phase.

What does the app do?

Users enter a date and select a work-and-release model. The app calculates the relevant dates and remaining workdays, then offers a daily dashboard, a narrated film, calendar tools and games.

How long did the project take?

Meyer says development ran from September 28 to October 2, 2026, with the public site online during that period. He published his account on October 13.

What did the AI coding agent do?

According to Meyer, the agent worked on code, tests, translations, voice clips and deployment. Meyer says he set the creative direction, made product decisions and approved releases.

Has the app’s accuracy been independently verified?

The source account does not cite an independent audit or testing results. It describes how the app calculates workdays, but does not provide external confirmation of the calculations.
