Insynskollen app icon

Insynskollen

I wanted to make insider trading easier to follow. Insynskollen uses AI summaries and push notifications to cut through the noise and help me find interesting companies on the Swedish stock market.

Kudoo WeightLoss

I wanted weight loss to feel simpler than counting calories. Kudoo uses a points system, daily step goals and AI food scanning to turn what you eat into points — making progress easier to understand and stick with.

First app ever shipped

Quiz game app icon

Prime Quiz

I just wanted to take an idea all the way to the App Store. It took a while, I learned a lot, and eventually I shipped my first app.

Product analytics

Built. Shipped. Measured.

I’d rather ship an MVP and learn from real users than guess what they want. That’s why I add tracking from the start — I want to understand what people actually do in the product and use that to decide what comes next.

Real behavior beats assumptions.

About

A little about me.

Viktor, the developer behind Devember

Hi, I’m Viktor. I started Devember as a place for my own ideas and projects.

I enjoy building things and figuring things out along the way. Some ideas stay small, some make it to the App Store, and some turn into products people actually pay for.

Devember is where I turn ideas into things I can actually use.
