Product, UX and game design consulting for mobile apps and games

We design for other teams too.

Most of our time goes into our own games. We keep room for a few consulting projects: mobile apps and games that need sharper product thinking, a UX audit or AI that actually helps.

What we help with

  1. UX reviews

    A UX audit of your app, screen by screen: what gets in people's way, and what to fix first.

  2. Onboarding and first sessions

    The first few minutes decide whether people come back. We map them and tighten them.

  3. Trust and safety

    A trust and safety audit for social and community apps: whether people feel safe, how reporting and blocking work, and what makes someone stay.

  4. AI and conversation features

    Assistants, characters and suggested messages that help people instead of decorating the product.

  5. Game design and systems

    Game design consulting: core loops, progression, economy and live ops, from pitch to launch.

UX reviews

Fresh eyes on every screen, and a clear plan for what to fix first.

After months inside a product, a team stops seeing it the way a newcomer does. We audit your app as a first-time user would, on real devices, and note every moment where people hesitate, misread a screen or give up. Then we rank what we find by impact, so your next sprint goes to the fixes that matter most.

What you get

  • A walkthrough of your key flows, with annotated screenshots.
  • Every issue in plain words: what happens, why it hurts, how to fix it.
  • Priorities ranked by impact and effort, ready for your backlog.
  • A session with your team to go through it together.

Right for you if

You are about to launch or redesign, or your numbers have dropped and nobody agrees on why.

Onboarding and first sessions

In a few minutes, people decide whether your app is for them. We make those minutes count.

We map everything a new user goes through, from the store page to the end of the first session, and what brings them back the next day. Then we cut steps, rethink what you ask for and when, and get people to the moment your product clicks as early as possible. It is the craft free-to-play games are built on, and it works just as well for apps.

What you get

  • A map of the first session, from install to the first real win.
  • Where people drop off and why, using your analytics if you have them.
  • A tighter flow: fewer steps, better-timed sign-up and permission requests, clearer first goals.
  • Changes written up as experiments your team can ship and measure.

Right for you if

People download your app, look around and never come back.

Trust and safety

People stay where they feel safe. We help you design that feeling, not just the rules.

In social and community products, safety is part of the experience: how people meet, what they can control, how fast a report gets an answer. We look at those moments from every side, the person being harassed, the person reported and the moderator in between, and design flows that protect people without making the app feel cold or suspicious.

What you get

  • An end-to-end review of reporting, blocking, muting and privacy settings.
  • Safer defaults for profiles, messages and first contact.
  • Clear, human wording for warnings, rules and moderation messages.
  • Ways to reward the people who make your community better, not only to punish those who make it worse.

Right for you if

You run a social app, a community or a game with chat, and you are growing faster than your safety tools.

AI and conversation features

AI that earns its place in your product, not a chatbot bolted on the side.

Our own game, Tokitopia, is built around AI companions, so we know where conversational features shine and where they fall apart. We start from what people are actually trying to do, give the AI a clear role and voice, and plan for the moments it gets things wrong. The result feels like part of your product, not a demo.

What you get

  • Where AI really helps in your product, and where it should stay out.
  • Characters and voice: personality, tone and limits.
  • Conversation flows and suggested replies your team can build.
  • Guardrails and fallbacks for when the AI is wrong, slow or out of its depth.

Right for you if

You are planning an assistant, an AI character or smart replies, or you shipped one and people are not using it.

Game design and systems

A great first hour sells a game. Its systems keep people playing for years.

Our game design is led by Javi San Juan, with more than fifteen years in free-to-play mobile games at Socialpoint, Scopely, Tripledot and Sandsoft, on titles like Dragon City and Scrabble GO. We bring that to your game: a core loop that is fun on its own, progression that keeps pulling players forward, and an economy that is fair to them and sustainable for you.

What you get

  • Core loop and progression design, documented and ready to prototype.
  • Economy design and tuning: sources, sinks, pricing and offers.
  • Live ops planning: events, seasons and the calendar that runs them.
  • Reviews of your pitch, design documents or vertical slice.

Right for you if

You are shaping a new game, or your live game needs a stronger reason for players to come back.

Background

Consulting work is led by Javi San Juan, our co-founder and game director, with more than fifteen years in free-to-play mobile games at Socialpoint, Scopely, Tripledot and Sandsoft. Past projects include Dragon City, Scrabble GO, Mundijuegos and Watermelee.

The AI work is led by Saurabh Nagarkar, our co-founder and AI research engineer. He built the AI behind Tokitopia's companions: characters that understand what players mean, reply in character and answer from the game's real rules instead of making things up. He also trains our own models, alongside the large language models we build on.
