Appothèque
A menu bar launcher for the Mac and iOS apps you are building: it rebuilds only when its inputs changed.

Every field runs on unwritten rules.I give them shape.
Botanists, researchers, teaching teams: I turn what they know into a precise need, then into working software.

Heading I
Tabular models for ecology
Where do tabular foundation models actually help on ecological data, and where don’t they?
Status Syntype v0.1 published and corrected; v0.1.1 waiting.
Read the correction -
Heading II
Generated interfaces
Can a model build a usable interface from a contract, a component catalogue and checkable evaluators?
Status Synthetic data and first evaluators.
-
Heading III
Independent apps
Which of my own tools can pay for my time?
Status LoopHuntr being published, Daymon in private beta, NamerKit in development.
Side trips a bookmark library sorted by a local model, couch games, a detective game set in 1913 London.

Independent apps
LoopHuntr
Loops for gravel, road and mountain bikes, hiking and trail running, built on the iPhone from a start point, a distance and a climb. Offline once a region is downloaded.
Games
Tales of Chinatown
A short detective game. Limehouse, 1913: connect clues, doubt what you are told, prepare the night. After Sax Rohmer.
Games
Futon Fighters
Couch games for up to four players on one screen: Ippon, a one-hit platform duel, and Fourtress, a split-screen first-person fight around a fort.
Developer tools
Daymon
Where working time actually goes. A local time tracker that shows what it is unsure about instead of guessing.
Independent apps
Slyfari
A private iOS browser with an encrypted video vault: what you save stays on the device, sealed with a key from the Keychain.
Research
Syntype
An open benchmark of tabular models on ecological data. Version 0.1 was corrected in public the day it came out.
github.com/syntype/syntypeMore projects
-
A naming studio for macOS: local or remote language models propose names, filters keep the reasons, and the newest mode shows unranked waves to sort by hand.
-
A daily journal written from the traces of agent sessions, and an archive other tools can query.
-
Browse and restore backups from Backblaze B2, SFTP and local folders, down to a single table of a PostgreSQL archive.
-
Small fixes upstream: Apple Silicon support in NVIDIA’s structured-data-models (#1032), a Codex integration and a PostgreSQL TLS fix in tabularis (#264, #278).
NVIDIA PR #1032 -
A regional biodiversity database: species records, taxonomy and maps for a very rich flora.
-
Plugins that take raw field inventories all the way to a published website.
-
Multi-school admissions for a private higher-education group: from the application to enrolment, documents, payments and interviews included.
-
The everyday system of the same group’s schools: timetables, grades, absences, admissions.
-
Reads an application’s logs and proposes fixes. The agent runs confined, and every suggestion comes with the evidence it rests on.
Notes
-
A second model reviewed Syntype and found four blocking issues: a survival task that mostly predicted harvest, modelled tree heights, a growth task solved by “next year equals this year”, and species reduced to their epithet. Public correction the same evening.

Multi-signal attribution in Daymon
The hardest problem in automatic time tracking isn’t capturing activity — it’s attributing it to the right project. When you switch between a browser tab, a terminal, and an IDE in the span of 30 seconds, which project owns that time?
Itinerary
Since 2009: plant identification, herbarium publishing, education platforms, biodiversity data. Today: tabular foundation models on ecological data, interfaces generated from a contract, and a few independent apps.

- INRA, AMAP lab Lead developer, Pl@ntNet
- App Store First Pl@ntNet iOS app: identify a plant from a photo
- Independent Education platforms, biodiversity data, business applications
- Arsis Tabular models, generated interfaces, independent apps
