A studio of apps

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. EU-hosted, with passkeys.

Frintake fridge home. Soccer practice, tonight ceviche, and FrinAI.

02 — Paper desk

Paper trade. Real charts. AI.

Learn the market without risking money.

Real market data, real charts, a paper account, and J-Bot. No real money. No real orders.

JTradeX in dark mode. BTC-USD weekly and TSLA daily candlestick charts, side by side.
JTradeX on a phone in dark mode. TSLA daily candlesticks with the trade ticket below the chart.

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.

OpenRouter figures are dated. Street and electricity figures are authored ballparks.

FitStack leaderboards in dark mode. Rankings for models, tools, and languages.

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.

SafetyBot. Hold to talk, add up to three photos, or type a safety case.

The studio

One name, four doors.

Julpukka is a studio of four apps. Each one keeps its own site.
