Two products from this year. Every recording on this page is the real app, captured on a phone and an emulator, not a mockup.

Servers chosen by real traffic, not by ping.

    One tap to connect

    Auto-pick chooses the best server for your network and swaps it the moment the connection starts to drag.

  2. 02

    Checked with real traffic

    Every server is tested by actually passing data through it. Speed, latency, jitter and a quality score, not just a ping.

  3. 03

    Knows your carrier

    Carrier badges show where each server worked in the last 24 hours, so the app suggests what works on your SIM.

Snap your plate and get calories and macros in seconds.

View case
  1. 01

    Send a photo, watch it think

    Or a sentence, a voice note, a receipt. Each product is researched in parallel, and progress shows item by item instead of a spinner.

  2. 02

    Correct anything

    Tap a product and change the portion, or simply write “the rice was 150 g”. The meal and the whole day recalculate at once.

  3. 03

    See the whole day

    Calories left, macros and fibre at a glance. The diary, the norm and the goals are one tap away.

How we work

Fast, and you see every step

Speed without surprises comes from one rule: you approve the design before we write code, and you hold a working build every week after that.

  • Nothing is coded without your sign-off
  • A build on your phone every week
  • Fixed price per stage
The process in detail

  1. 01 · Day 1

    A brief instead of a call

    You fill in a short brief, we ask what is left in writing. The goal, the audience and the one thing the app must do well end up on a single page you can forward to anyone.

    • One-page brief
    • List of open questions

  2. 02 · Within 24 hours

    Estimate with a fixed price per stage

    Scope, timeline and a fixed price for each stage instead of an hourly meter. You know what the prototype costs before you decide on the rest.

    • Scope and timeline
    • Fixed price per stage

  3. 03 · About a week You approve here

    Clickable prototype you approve

    Flows, then a clickable Figma prototype you tap through on your own phone. Comments go right on the screens. Nothing is coded until you say yes.

    • Clickable prototype
    • Design system
    • Your sign-off

  4. 04 · Weekly

    Build in short sprints

    Every week you get the working app on your phone (TestFlight on iPhone, an APK on Android, a link for Mini Apps) and a short video of what changed.

    • A build every week
    • Video demo
    • Transparent board

  5. 05 · Launch

    Store release and analytics

    Listings, screenshots, review and release. Crash reporting and product analytics are in from day one, so the first users already teach us something.

    • App Store and Google Play
    • Analytics and crash reports

  6. 06 · After launch

    Support and growth

    New OS versions, A/B tests, features the numbers ask for. The code and all accounts stay yours, so you can take them to any team at any time.

Beyond apps

Bots and Mini Apps, where we started

Our bot studio SkyBots has launched more than 100 bots since 2018: ordering, subscriptions, support, AI. Here is how they talk and what they grew into.

FAQ

Before you ask

How much does an app cost?

It depends on scope, so we do not quote in the dark. After a short brief (no calls needed) you get an estimate within one business day, with a fixed price for each stage. The prototype stage is small and lets you check us before committing to the rest.

How fast can you ship?

A clickable prototype usually takes about a week. A focused MVP of a mobile app takes four to eight weeks, a Telegram Mini App two to six, and a bot can go live in a few days.

Will I see the design before development starts?

Yes, that is the rule. You tap through a clickable prototype on your own phone and approve every screen. Development starts only after your sign-off.

Do you publish to the App Store and Google Play?

Yes. We prepare listings and screenshots, go through review and handle rejections. We also ship through TestFlight, RuStore or a direct APK with signed updates when the product needs it.

Who owns the code and the accounts?

You do. Repositories, developer accounts and servers are registered to you from day one, so you can move to another team at any time.

Do you work with clients outside Russia?

Yes. We work remotely, in English or Russian. Briefs, prototypes, weekly builds and video demos all work in writing, across time zones.
