A studio of apps
Julpukka
A small studio of apps. A kitchen door, a paper trading desk, a stack guide, and a safety report you can speak.
01 — Kitchen
The family week, on one door.
Dinner included.
Calendar, fridge, recipes, and FrinAI. Plan dinner from what is already there. English, Finnish, or Swedish.
On the App Store now. Coming soon to Google Play. The first month includes FrinAI and photo scans; after that Frintake Pro is €9.99 a month per household, not per person. EU-hosted, with passkeys.
The light interface, inside a dark kitchen.
02 — Paper desk
Paper trade. Real charts. AI.
Learn the market without risking money.
Real prices, real charts, a paper account, and J-Bot. No real money. No real orders.
Free covers core charts, learning, and limited AI. Pro adds unlimited AI Daily Briefs, full J-Bot modes, and higher limits.
Dark mode. The chart, then analysis.
03 — Stack guide
The stack that fits.
A guide, not a directory.
Describe the job. FitStack lines up a cloud path, a builder-in-the-middle, or a local stack. Recipes stay with their authors.
Prices from OpenRouter are dated. Street prices and electricity are authored ballparks.
Dark mode. Home, then leaderboards.
04 — Field report
Speak or photograph a safety case.
Hold the button and tell us what happened.
Up to three photos, or type instead. SafetyBot writes the report and sends it on. It is not the official record.
Early preview, v0.1.7, MIT. Not a medical, legal, or certified incident system.
The worker screen stays light.
The work
Four live products.
Each tile opens that product. Frintake and JTradeX also have their stores.
The studio
One name, four doors.
Julpukka is a studio of four apps. The name is on the work — including the Frintake copyright, © 2026 Julpukka.
The products stay separate. A household kitchen. A paper trading desk. A guide for choosing a stack. A screen where a safety case can be spoken or photographed. Each one keeps its own site.
