Mobile apps people open every day.
From the idea to your customer’s phone — design, code, subscriptions, AI inside and publishing to the stores. We know the road to a live app: TITAN, our own AI fitness coach in 7 languages, runs straight from the browser, and its Google Play version is in closed testing.

What we build
Apps that earn their keep.
An app isn’t a business card in the store. It sells, brings customers back or saves your team hours — otherwise it isn’t worth building. Here’s what we build.
Subscription products
The app is the business: free trial, subscription, retention. Exactly like TITAN.
An app for your customers
Orders, loyalty points and notifications — your store or restaurant in your customer’s pocket.
AI apps
A coach, adviser or assistant that remembers the user’s history and answers like a person.
Apps for your team
For people in the field: tasks, site photos, statuses and signatures — synced with the office.
Bookings and appointments
Schedules, booking and reminders — no phone tag and no missed appointments.
A companion to your site or system
The same products, customers and orders as your website and admin — no double entry.
PWA or the app stores
Web app or App Store? The honest answer.
Not every idea needs the App Store from day one. Here’s the difference — and the road we took with TITAN.
How TITAN does it: today it runs on Android straight from the browser, and the Google Play version is in closed testing. The product is live without waiting for a store’s approval — while the store version is prepared in parallel.
Our own product
TITAN. Built from zero.
We’re not selling you theory. TITAN is our own AI app — a personal plan, nutrition targets and an AI coach that remembers every set you’ve logged and pushes like a human. Product logic, the AI conversation, design, languages — all built in-house.
- A personal plan in two minutes — goal, level, schedule, equipment
- Five AI coaches — one method, five very different voices
- A free trial with no card, a subscription, cancel from Settings
- Seven languages in one product

Subscriptions and payments
An app that pays its own bills.
Monetization isn’t bolted on at the end — we build it into the product from day one. Here’s what that looks like in TITAN today.
- A free trial — no card needed
- A monthly subscription, priced by country
- Cancel any time from Settings — no emails, no calls
- “Bring a friend” — both get bonus days
- A founder badge and skill levels earned with real results
- Pages for the right of withdrawal and refunds
AI inside the app
Not another button. A brain in their pocket.
AI that remembers the user, speaks up at the right moment and leads to the next step — a purchase, a workout, a booking. We build it with predictable costs, because we pay for it in our own product too.
Can we get a table for four on Friday, around 8pm?
You’re in, Marcus — the window booth is free at 8pm. You also have 240 points, enough for a free dessert. Want me to add it to the booking?
Yes please. And can we pre-order the tasting menu?
All set ✓ Friday at 8pm, a booth for four, the tasting menu pre-ordered and dessert on us — it’s all in your bookings. See you at 8!
AI that remembers
The user’s history makes every answer personal — the way TITAN reads every logged set.
Notifications at the right moment
The app speaks up when it’s time — TITAN’s coach already knows the plan.
Character and voice
Five coaches in TITAN — from a brutal enforcer to a calm technician. One method, different tones.
Personal recommendations
A product, a plan or the next step — based on behavior, not guesswork.
Many languages
One app, many markets: TITAN speaks 7 languages.
Predictable AI costs
Every AI reply costs money. We design it so the free trial doesn’t eat your margin.
From idea to the store
Four steps to your customer’s phone.
-
01
An idea and an honest call
30 minutes, free: what the app solves, who it’s for and how it will make money. We’ll tell you if a website or a PWA would do the same job for less.
-
02
Prototype and a custom quote
The screens and the user’s journey before we write a line of code. Price and timeline in writing.
-
03
Test it on your phone
A working version on your own phone from the first days. You try it and comment; we build.
-
04
Launch and growth
We launch in the browser and prepare the App Store and Google Play versions, store reviews included. Then: updates, new features and a look at what people actually use.
What we take on — end to end
One partner for the whole road. No hiring a designer, a developer and an “app store person” separately.
- Design of the screens, the icon and the user journey
- Code for iPhone and Android — or a PWA
- Server, database and admin panel
- Sign-up, profiles and subscriptions
- Push notifications and automatic emails
- AI features — and control over what they cost
- Privacy, withdrawal and refund pages
- Preparation and submission to the App Store and Google Play
Zero risk
We build for ourselves, too.
Our own product on the market
TITAN is ours. We know first-hand what AI costs per user and how subscriptions are built — and we tell you before we start.
Custom quote in writing
Price and timeline in the quote before we begin. No hourly rates, no surprises at the end.
On your phone from the first days
You try a working version while we build — instead of staring at mockups for months.
Everything is yours
The code, the data and the App Store and Google Play accounts — in your name. Care is optional.
FAQ
Before you ask.
Can’t find your question? Write to us or ask our AI assistant — it answers right away.
How much does a mobile app cost?
It depends on whether it’s a PWA or in the stores, how many screens and roles it has, and whether there are subscriptions, payments, AI and integrations. So we don’t quote a number out of thin air: after a free 30-minute call you get a custom quote in writing — price, timeline and exactly what’s included.
How long does it take?
It depends on the scope, and the timeline goes into the quote. The fastest route is a PWA — a working app on the phone without waiting for a store review. You see a working version from the first days of the build.
Is it for iPhone or Android?
Both. A PWA runs on both straight from the browser. When the product needs the stores, we publish to the App Store and Google Play.
PWA or the App Store and Google Play — which should I choose?
For most new products: PWA first, then the stores. You launch faster and for less, and you learn from real users. TITAN runs on Android straight from the browser today, with the Google Play version in closed testing — exactly that route. If you need sensors, background work or a store presence from day one, we go native from the start.
Can it take subscriptions and payments?
Yes. TITAN runs a free trial with no card, a monthly subscription priced by country and cancellation any time from Settings. For digital content in the App Store and Google Play, their payment rules apply — we explain them before we start, so there are no surprises in your margin.
What will the AI cost me after launch?
AI has a cost every time it’s used. So we design for a predictable cost per user — limits, the right model for each task, and a free trial that doesn’t eat your revenue. We know this from TITAN, where free days with an AI coach cost real money.
Who owns the app?
You do. The code, the data and the App Store and Google Play accounts are in your name. Care is optional — no lock-in.
I already have a website or online store. Can the app use the same data?
Yes. The app can read the same products, customers and orders as your website and admin — no double entry. If there’s no system behind it yet, we build that too: see custom systems.
What happens after launch?
30 days of care are included. After that, optional ongoing care: updates for new iOS and Android versions, monitoring and new features. The terms go into your quote, so you know the monthly figure up front.
