Problem the app solves

Travelers are tired of overhyped places that are expensive, crowded, and soulless. People try to fix this in a few ways.

FOLLOWING INFLUENCERS

Some people get an advice from YouTube or Instagram creators. It can work, but it’s hard to find someone you can actually trust. Plus, some influencers sell PDF guides for 20–30 €.

TRAVEL APPS

Most travel apps are way too generic and shallow, which usually just leaves you feeling more frustrated.

GOOGLE MAPS

Google Maps is great, but there are thousands of options, even with a high rating filter — still dozens of places.

AI ASSISTANTS

AI is a game-changer, but only if you know exactly what to ask — otherwise, it just gives you the most generic tips.

UNDERHYPE ROLE

Underhype cuts the noise. It focuses strictly on Sweden and relies on strong editorial reviews. Plus, it navigates user in every part of the journey: arriving, transportation, eating, walking, shopping, leaving the city.

Problem the app solves

I kept the language consistent across the product, chose words people actually use, and avoided abstract terms so users could easily picture exactly what I meant.

Story in the center of the design

Story in the center of the design

The idea of Underhype — cut the noise and avoid mainstream. This idea rules everything in the product.

Use a serif font
rare for modern interfaces
Stick to a local .se domain
instead of a flashy one like .app
Limit tips: 3-5 per category, like cafés,
instead of hundred options
Strong editorial control
over AI suggestions
Focus on one market
instead of being an everything app

Shipping with AI assistants

Shipping with AI assistants

Since I was working solo and had limited time, I built everything directly in V0 app, that works on Claude. I used v0 design system. It allowed to move fast and focus on adapting the components to my needs, rather than building from scratch. And only then I moved results from v0 to Figma — just because sometimes it's faster and cheaper to play with design in Figma rather than in v0 directly.

Documenting the logic of the app

Documenting the logic of the app

To "vibe-code" something that actually works, you have to give the AI crystal-clear instructions. I used what I learned back at Yandex — an enterprise-level tech company — and documented every step from both the user and system perspective. At the end of the day, it was a lot like a PM job: sending detailed specs to an engineering team.

Shipping on time

Shipping on time

I follow the Basecamp principle: Fix Time and Budget, Flex Scope — instead of launching everything at once, I release features one by one to hit deadlines.

EXAMPLE

In the first version, I cut extra graphics to focus on core features. I tested and launched features before my deadline.

What's next

What's next

Since I’m solo, I’ve sized every task to make sure I stay on track and keep shipping.
