Trond Kristiansen
I build small tools often just for fun at the intersection of learning, performance support, and applied AI.
What I work on
I enjoy making small apps for myself, family and friends to make life better.
For work I am interested in how people perform — how they acquire, use and develop knowledge in their work — and how we can support them while they work.
Works
-
Spor
iOS diary that pairs symptoms with what you take in — meals, drinks, medication, supplements. Surfaces ingredient patterns as candidates for a clinician conversation, never as diagnoses. This is your information so it is: local-first, optional iCloud sync, no analytics, no streak mechanics. SwiftData, SwiftUI, Swift Charts.
-
Linear Calendar
A native macOS calendar that shows all twelve months at once, based on Nick Milo's Linear Calendar idea — put what matters on the year before everything else fills it up. Milestones, Apple Calendar, a calendar-load heat map, and an optional bring-your-own-key AI assistant using Claude and agent skills. I hope to release it as open source, local-first, optional iCloud sync.

Agent Skills
Writing agent skills for colleagues, and my own use. Not a product, just hacking my job.
