Globdrop
A geography game. Place cities, landmarks and fictional islands on a map, or name flags against the clock. 16 scenarios, free to play, with ads.
Projects
A game, two apps, a 3D history of places and a set of calculators. They all run in your browser, none of them asks you for an account, and each page says what the project can't do. KeepLanding, a game about landing and taking off, is coming soon.
Andamio
A Gantt editor that lives in your browser. Plans are saved on your device and export to JSON, Mermaid and SVG.
Ahorreo
Personal finance built from the statements your bank already gives you. Files are read and stored on your device; there is no server behind it.
Chronotopia
Places rebuilt in 3D, year by year: Barcelona–El Prat, Ibiza and Palma de Mallorca airports from their first fields to the works planned for the 2030s, with the sources for every stage.
KeepLanding
A game about landing and taking off. Repeat it endlessly, take on a 56-runway challenge all the way to Es Vedrà, or fly in relax mode with no collapse and no clock. Coming soon to Android, iOS and Steam.
Tools
Small calculators that grew out of our own projects: task buffers with PERT, how much a map projection distorts area and shape, and a mortgage with your share of it.
How they came about
Andamio came first: its repository starts on 13 March 2026, when we wanted a plan we could draw in minutes and keep on our own machine. Globdrop followed on 8 May 2026, when the small map games we had been making before it had a name became one game. Ahorreo started on 8 September 2026, to see money spread across several banks and shared accounts without handing anyone our bank logins. Chronotopia is the youngest, started on 26 September 2026: a 3D model of Barcelona–El Prat that you can move through year by year, which Ibiza joined the next day and Palma de Mallorca on 3 October. The same engine is now building its first monument, the Sagrada Família.
The calculators came out of those three. The buffer calculator estimates how much buffer to give the tasks in a plan like the ones you draw in Andamio, the distortion calculator shows the projection problem every Globdrop map has to solve, and the mortgage calculator splits a loan the way Ahorreo counts your share of it. Each one is a single page, with the maths explained below the result.
They share a way of working more than a codebase: each app is its own repository with its own stack, from plain TypeScript in Globdrop to React in Andamio and Ahorreo. What they have in common is in the table below, and each project page has a section on its limits.
At a glance
| Project | What it stores, and where | Ads |
|---|---|---|
| Globdrop | Only preferences (language, theme), in localStorage | Yes, inside the game |
| Andamio | Your plans, in localStorage | No |
| Ahorreo | Your finances, in IndexedDB, plus encrypted backup files you keep | No |
| Chronotopia | Two values in localStorage, so its note about Momusa or Sindria shows at most once a day; the place, year and language are in the page address | No ad network; links to Momusa and Sindria |
| Tools | Nothing: results are worked out on the page | One per tool, below the result |
